In the case of actually setting the auto switches, adjust them after confirming their operation. Note 2) Negative figures in the table W indicate an auto switch is mounted inward from the edge of the cylinder body. Note 3) In the case of the 5 stroke or the 10 stroke, there are times in which the switch will not turn OFF or 2 switches will turn ON simultaneously due to their movement range. Therefore, set the position approximately 1 to 4 mm outward from the values given in the table above. Then, perform an operation inspection to make sure that the switches operate normally (if 1 switch is used, make sure that it turns ON and OFF properly; if 2 switches are used, make sure that both switches turn ON). Note 4) ( ) in column W is the dimensions of D-A93.

Caution on Proximity Installation
When free mounting cylinders equipped with auto switches are used, the auto switches could activate unintentionally if the installed distance is less than the dimensions shown in the table. Therefore, make sure to provide a greater clearance. Due to unavoidable circumstances, if they must be used with less distance than the dimensions given in the table, the cylinders must be shielded. Therefore, affix a steel plate or a magnetic shield plate (MU-S025) to the area on the cylinder that corresponds to the adjacent auto switch. (Please contact SMC for details.) Auto switches may malfunction if a shield plate is not used.

In the case of actually setting the auto switches, adjust them after confirming their operation. Note 2) Negative figures in the table W indicate an auto switch is mounted inward from the edge of the cylinder body. Note 3) In the case of the 5 stroke or the 10 stroke, there are times in which the switch will not turn OFF or 2 switches will turn ON simultaneously due to their movement range. Therefore, set the position approximately 1 to 4 mm outward from the values given in the table above. Then, perform an operation inspection to make sure that the switches operate normally (if 1 switch is used, make sure that it turns ON and OFF properly; if 2 switches are used, make sure that both switches turn ON). Note 4) ( ) in column W is the dimensions of D-A93.

Note 1) Figures in the table above are used as a reference when mounting the auto switches for stroke end detection. In the case of actually setting the auto switches, adjust them after confirming their operation. Note 2) Negative figures in the table W indicate an auto switch is mounted inward from the edge of the cylinder body. Note 3) In the case of the 5 stroke or the 10 stroke, there are times in which the switch will not turn OFF or 2 switches will turn ON simultaneously due to their movement range. Therefore, set the position approximately 1 to 4 mm outward from the values given in the table above. Then, perform an operation inspection to make sure that the switches operate normally (if 1 switch is used, make sure that it turns ON and OFF properly; if 2 switches are used, make sure that both switches turn ON).

Operating Precautions
Allowable Rotational Torque
Bore size (mm) Allowable rotational torque (N*m)
Caution
1. Do not place your fingers in the clearance between the non-rotating plate and the cylinder tube. Your fingers could get caught between the non-rotating plate and the cylinder tube when the piston rod retracts. Therefore, never place your finger in this area. Because the cylinder outputs a great force, it could lead to injury if precautions are not taken to prevent your fingers from getting caught. 2. When using the non-rotating style, make sure that rotational torque is not applied to the piston rod. If rotational torque must be applied due to unavoidable circumstances, make sure to use it at the allowable rotational torque or less, which is shown in the table on the right.

Unique air cushion construction requires no cushion ring.
Elimination of the cushion ring used in conventional type air cushions has made it possible to reduce the overall length of the cylinder while retaining all the advantages of a compact profile.
Working principle
A + A'
A'
When the piston is retracting, air is exhausted through both A and A' until piston seal H passes air passage A.
A A' R
Piston seal
A' R H
After piston seal H has passed air passage A, air is exhausted only through A'. The section marked with slanted lines becomes a cushion chamber, and an air cushion effect is achieved. When air is supplied for the piston extension, the check valve opens and the piston extends with no delay.

Caution on Proximity Installation
When free mounting cylinders equipped with auto switches are used, the auto switches could activate unintentionally if the installed distance is less than the dimensions shown in the table. Therefore, make sure to provide a greater clearance. Due to unavoidable circumstances, if they must be used with less distance than the dimensions given in the table, the cylinders must be shielded. Therefore, affix a steel plate or a magnetic shield plate (MU-S025) to the area on the cylinder that corresponds to the adjacent auto switch. (Please contact SMC for details.) Auto switches may malfunction if a shield plate is not used.

Specific Product Precautions 1
Be sure to read before handling. Refer to back page 1 through to 6 for Safety Instructions, Actuator Precautions, and Auto Switch Precautions.
Installation and Removal of Snap Rings
Selection
Caution
1. Use appropriate pliers (Type C snap ring installing tool) for installation and removal of snap rings. 2. Even when using appropriate pliers (Type C snap ring installing tool), proceed with caution as there is a danger of the snap ring flying off the end of the pliers (tool) and causing bodily injury or damage to nearby equipment. After installation, make sure that the snap ring is securely seated into the snap ring groove before supplying air.
Caution
3. Adjust the cushion needle to reduce excessive kinetic energy from the piston impact at the stroke end by allowing it to absorb sufficient kinetic energy during the cushion stroke.
If due to improper adjustment, the piston impacts the stroke end with excessive kinetic energy (values above those given in Table (1)), an excessive impact will occur and this may cause damage to equipment.

Caution
1. Operate the cylinder to the stroke end.
When the stroke is restricted by an external stopper or a clamped workpiece, sufficient cushioning and noise reduction may not be achieved.
2. Strictly observe the limiting ranges for load weight and maximum speed (Graph (1)). Also, the limiting ranges provided here are based on the condition that the cylinder is operated to the stroke end with a proper cushion needle adjustment.
If operated beyond the limiting ranges, excessive impact will occur and this may cause damage to equipment. Graph (1)

Free Mount Cylinder for Vacuum
Series ZCUK
A free mount cylinder with a vacuum passage in the rod to meet the requirements for Air cylinder + Vacuum pad .
A vacuum passage has been provided in the rod of the CUK cylinder to enable a vacuum pad to be installed on the end of the rod.
Not necessary to provide vacuum tubing space at the end of the rod.
The area around the vacuum pad is uncluttered. Non-rotationg rod
A guide is provided as standard equipment Non-rotating rod accuracy (no load: when the rod is retracted on the detent plate side): o10, o16 0.8 o20, o25, o32 0.5 Do not apply a lateral load to the piston rod. Because the piston rod is a hollow rod, a lateral load can cause the piston rod to bend or break.
Auto switch
Reed switch: D-A9 (Heavy-duty cord, in-line entry) D-A9V (Heavy-duty cord, perpendicular entry) Solid state switch: D-M9, D-F9W (Heavy-duty cord, in-line entry) D-M9V, D-F9WV (Heavy-duty cord, perpendicular entry)
How to provide piping to the vacuum side
Cap piping
The piston rod of the vacuum side does not protrude. Also, the vacuum outlet tube does not move when the piston is operating. Vacuum port pressure range: -101 kPa to 0.6 MPa Pressurize only when releasing the vacuum. At that time, use it under the cylinder operating pressure.
Vacuum pad (Pad diameter: o2 to o50)

Rod piping
Lighter weight than the cap piping. Can also be used for air blowing. Vacuum port pressure range: -101 kPa to 0.6 MPa

Caution
1. Do not place your finger in the clearance between the detent plate and the cylinder tube. Never put your finger between the nonrotating plate and cylinder tube. Your finger may be pinched when the piston rod retracts. If your finger is caught, it could injure your finger because the cylinder outputs a considerable amount of force. 2. Make sure that rotational torque is not applied to the piston rod. If this is unavoidable, operate the cylinder within the allowable rotational torque listed in the table below.
JIS Class 2 With or without (Pad direct mounting) Basic style Refer to next page for details. Note) For a cap style, supply pressure only when vacuum is released. That pressure should be less than the cylinder pressure.

Note 1) Figures in the table above are used as a reference when mounting the auto switches for stroke end detection. In the case of actually setting the auto switches, adjust them after confirming their operation. Note 2) Negative figures in the table show dimensions mounted inside cylinder body. Note 3) In the case of 5 mm stroke or the 10 mm stroke, there are times in which the switch will not turn OFF or 2 switches will turn ON simultaneously due to their movement range. Therefore, set the position approximately 1 to 4 mm outward from the values given in the table above. Then, perform an operation inspection to make sure that the switches operate normally (if 1 switch is used, make sure that it turns ON and OFF properly; if 2 switches are used, make sure that both switches turn ON). Note 4) Figures in ( ) in the table W are D-A93.

Cautions on Proximity lnstallation
When free mounting cylinders equipped with auto switches are used, the auto switches could activate unintentionally if the installed distance is less than the dimensions shown in the table. Therefore, make sure to provide a greater clearance. Due to unavoidable circumstances, if they must be used with less distance than the dimensions given in the table, the cylinders must be shielded. Therefore, affix a steel plate or a magnetic shield plate (MU-S025) to the area on the cylinder that corresponds to the adjacent auto switch. (Please contact SMC for details.) Auto switches may malfunction if a shield plate is not used.
* To tighten the auto switch mounting screws, use a watchmaker's screwdriver with a grip diameter of 5 to 6 mm. * Tighten the screws to a torque of approximately 0.10 to 0.20 N*m.

When two switches are connected in series, a load may malfunction because the load voltage will decline when in the ON state. The indicator lights will light up if both of the switches are in the ON state.
(Reed switch)
Because there is no current leakage, the load voltage will not increase when turned OFF. However, depending on the number of switches in the ON state, the indicator lights may sometimes dim or not light because of the dispersion and reduction of the current flowing to the switches.

Note 1) ISO 4414: Pneumatic fluid power--General rules relating to systems. Note 2) JIS B 8370: General Rules for Pneumatic Equipment
Warning
1. The compatibility of pneumatic equipment is the responsibility of the person
who designs the pneumatic system or decides its specifications.
Since the products specified here are used in various operating conditions, their compatibility with a specific pneumatic system must be based on specifications, post analysis and/or tests to meet a specific requirement. The expected performance and safety assurance is the responsibility of the person who determines the compatibility of the system. This person should continuously review the suitability of all specified items by referring to the latest information in the catalog and by taking into consideration the possibility of equipment failure when configuring the system.
2. Only trained personnel should operate pneumatically operated machinery
and equipment.
Compressed air can be dangerous if an operator is unfamiliar with it. Assembly, handling or repair of pneumatic systems should be performed by trained and experienced operators.
3. Do not service machinery/equipment or attempt to remove components until
safety is confirmed.
1. Inspection and maintenance of machinery/equipment should only be performed once measures to prevent falling or runaway of the driver objects have been confirmed. 2. When equipment is to be removed, confirm the all safety precautions have been followed. Cut the supply pressure for this equipment and exhaust all residual compressed air in the system. 3. Before restarting any machinery/equipment, excercise caution to prevent quick extension of a cylinder piston rod, etc.
4. Contact SMC if the product is to be used in any of the following conditions:
1. Conditions and environments beyond the given specifications, or if product is used outdoors. 2. Installation on equipment in conjunction with atomic energy, railway, air navigation, vehicles, medical equipment, food and beverages, recreation equipment, emergency stop circuits, clutch and brake circuits in press applications, or safety equipment. 3. An application which has the possibility of having a negative effect on people, property, or animals, requiring special safety analysis.

Series CU
Actuator Precautions 1
Be sure to read before handling.
Caution on Design
Selection
Warning
1. There is a possibility of dangerous sudden action by air cylinders if sliding parts of machinery are twisted due to external forces, etc.
In such cases, human injury may occur; e.g., by catching hands or feet in the machinery, or damage to the machinery itself may occur. Therefore, the machine should be adjusted to operate smoothly and designed to avoid such dangers.
Warning
1. Confirm the specifications.
The products featured in this catalog are designed for use in industrial compressed air systems. If the products are used in conditions where pressure and/or temperature are outside the range of specifications, damage and/or malfunctions may occur. Do not use in these conditions. (Refer to the specifications.) Consult with SMC if you use a fluid other than compressed air.
2. A protective cover is recommended to minimize the risk of personal injury.
If a stationary object and moving parts of a cylinder are in close proximity, personal injury may occur. Design the structure to avoid contact with the human body.
Caution
1. Operate within the limits of the maximum usable stroke.
The piston rod will be damaged if operated beyond the maximum stroke. Refer to the air cylinder's model selection procedure for the maximum stroke availability.
3. Securely tighten all stationary parts and connected parts so that they will not become loose.
Especially when a cylinder operates with high frequency or is installed where there is a lot of vibration, ensure that all parts remain secure.
4. A deceleration circuit or shock absorber may be required.
When a driven object is operated at high speed or the load is heavy, a cylinder's cushion will not be sufficient to absorb the impact. Install a deceleration circuit to reduce the speed before cushioning, or install an external shock absorber to relieve the impact. In this case, the rigidity of the machinery should also be examined.
2. Operate the piston within a range such that collision damage will not occur at the stroke end.
Operate within a range such that damage will not occur when the piston, having inertial force, stops by striking the cover at the stroke end. Refer to the cylinder model selection procedure for the range within which damage will not occur.
5. Consider a possible drop in circuit pressure due to a power outage, etc.
When a cylinder is used in a clamping mechanism, there is a danger of workpieces dropping if there is a decrease in clamping force due to a drop in circuit pressure caused by a power outage, etc. Therefore, safety equipment should be installed to prevent damage to machinery and human injury. Suspension mechanisms and lifting devices also require consideration for drop prevention.
3. Use a speed controller to adjust the cylinder drive speed, gradually increasing from a low speed to the desired speed setting.
Mounting
Caution
1. Be certain to match the rod shaft center with the direction of the load and movement when connecting.
When not properly matched, problems may arise with the rod and tube, and damage may be caused due to friction on areas such as the inner tube surface, bushings, rod surface and seals.
6. Consider a possible loss of power source.
Measures should be taken to protect against bodily injury and equipment damage in the event that there is a loss of power to equipment controlled by pneumatics, electricity, or hydraulics.
7. Design circuitry to prevent sudden lurching of driven objects.
When a cylinder is driven by an exhaust center type directional control valve or when starting up after residual pressure is exhausted from the circuit, etc., the piston and its driven object will lurch at high speed if pressure is applied to one side of the cylinder because of the absence of air pressure inside the cylinder. Therefore, equipment should be selected and circuits designed to prevent sudden lurching, because there is a danger of human injury and/or damage to equipment when this occurs.
2. When an external guide is used, connect the rod end and the load in such a way that there is no interference at any point within the stroke. 3. Do not scratch or gouge the sliding parts of the cylinder tube or tube rod, etc., by striking or grasping them with other objects.
Cylinder bores are manufactured to precise tolerances, so that even a slight deformation may cause malfunction. Also, scratches or gouges, etc., in the tube rod may lead to damaged seals and cause air leakage.
8. Consider emergency stops.
Design so that human injury and/or damage to machinery and euqipment will not be caused when machinery is stopped by a safety device under abnormal conditions, a power outage or a manual emergency stop.
4. Prevent the seizure of rotating parts.
Prevent the seizure of rotating parts (pins, etc.) by applying grease.
9. Consider the action when operation is restarted after an emergency stop or abnormal stop.
Design the machinery so that human injury or equipment damage will not occur upon restart of operation. When the cylinder has to be reset at the starting position, install manual safely equipment.

Mounting
Air Supply
Caution
5. Do not use until you verify that the equipment can operate properly.
After mounting, repairs, or modification, etc., connect the air supply and electric power, and then confirm proper mounting by means of appropriate function and leak tests.
Caution
1. Install air filters.
Install air filters close to valves at their upstream side. A filtration degree of 5 m or less should be selected.
6. Instruction manual
Install the products and operate them only after reading the instruction manual carefully and understanding its contents. Also keep the manual where it can be referred to as necessary.
2. Install an aftercooler, air dryer, or water separator (Drain Catch).
Air that includes excessive drainage may cause malfunction of valves and other pneumatic equipment. To prevent this, install an air dryer, aftercooler or water separator, etc.
3. Use the product within the specified range of fluid and ambient temperature.
Take measures to prevent freezing when below 5C, since moisture in circuits can freeze and cause damage to seals and lead to malfunctions. For details on the quality of compressed air mentioned above, refer to SMC's "Best Pneumatics" catalog vol. 14.
Piping
Caution
1. Preparation before pipig
Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil and other debris from inside the pipe.
Operating Environment
2. Wrapping of pipe tape
When screwing in pipes and fittings, etc., be certain that chips from the pipe threads and sealing material will not ingress inside the piping. Also, when pipe tape is used, leave 1.5 to 2 thread ridges exposed at the end of the threads.
Wrapping direction
Warning
1. Do not use in atmospheres or locations where corrosion hazards exist. 2. In dusty locations or where water or oil, etc., splash on the equipment, take suitable measures to protect the rod. 3. When using auto switches, do not operate in an environment with strong magnetic fields.
Maintenance

Warning
1. Perform maintenance procedures as shown in the instruction manual.
If it is handled improperly, malfunction or damage of machinery or equipment may occur.
Lubrication
Caution
1. Lubrication to cylinders
The cylinder has been lubricated at the factory and can be used without any further lubrication.
2. Removal of equipment, and supply/exhaust of compressed air
Before any machinery or equipment is removed, first ensure that the appropriate measures are in place to prevent the fall or erratic movement of driven objects and equipment, then cut off the electric power and reduce the pressure in the system to zero. Only then should you proceed with the removal of any machinery and equipment. When machinery is restarted, proceed with caution after confirming that appropriate measures are in place to prevent cylinders from sudden movement.
Air Supply
Warning
1. Use clean air.
Do not use compressed air which contains chemicals, synthetic oils containing organic solvents, salts or corrosive gases, etc., as this can cause damage or malfunction.
Caution
1. Drain flushing
Remove drainage from air filters regularly.

Auto Switch Precautions 1
Be sure to read before handling.
Design and Selection
Warning
1. Confirm the specifications.
Read the specifications carefully and use this product appropriately. The product may be damaged or malfunction if it is used outside of its specification range (eg. current load, voltage, temperature or impact, etc.).
5. Pay attention to leakage current.
With a 2-wire solid state auto switch, current (leakage current) flows to the load to operate the internal circuit even when in the OFF state. Current to operate load Leakage > (Input OFF signal of controller) current If the condition given in the above formula is not met, internal circuit will not reset correctly (stays ON). Use a 3-wire switch if this specification cannot be satisfied. Moreover, leakage current flow to the load will be "n" times larger when "n" auto switches are connected in parallel.
2. Pay attention to the length of time that a switch is on at an intermediate stroke position.
When an auto switch is placed at an intermediate position of the stroke and a load connected to the auto switch is driven at the time the slide table passes, the auto switch will operate. However if the speed is too great, the operating time will be shortened and the load may not operate properly. The maximum detectable piston speed is: V (mm/s) = Auto switch operating range (mm) i 1000 Load operating time (ms)
6. Do not use a load that generates surge voltage.
If driving a load such as a relay which generates a surge voltage, use a contact protection box. Although a zener diode for surge protection is connected at the output side of a solid state auto switch, damage may still occur if a surge is applied repeatedly. When directly driving a load which generates a surge, such as a relay or solenoid valve, use a switch with a built-in surge absorbing element.
3. Keep wiring as short as possible.
As the length of the wiring to a load gets longer, the rush current at the time the switch is turned ON becomes greater, which may shorten the product's life. (The switch will stay ON all the time.) 1) Use a contact protection box when the wire length is 5 m or longer. 2) Although the wire length should not affect switch function, use a wire that is 100 m or shorter.
7. Cautions for use in an interlock circuit
When an auto switch is used for an interlock signal requiring high reliability, devise a double interlock system to safeguard against malfunctions. The double interlock system should provide a mechanical protection function or use another switch (sensor) together with the auto switch. Also perform periodic inspection and confirm proper operation.
4. Take precautions for the internal voltage drop of the switch.
1) Switches with an indicator light (Except D-A96, A96V) * If auto switches are connected in series as shown below, take note that there will be a large voltage drop because of internal resistance from the light emitting diodes. (Refer to internal voltage drop in the auto switch specifications.) [The voltage drop will be "n" times larger when "n" auto switches are connected.] Even though an auto switch operates normally, the load may not operate.
Load
8. Ensure sufficient clearance for maintenance activities.
When designing an application, be sure to allow sufficient clearance for maintenance and inspections.
* Similarly, when operating below a specified voltage, it is possible that the load may be ineffective even though the auto switch function is normal. Therefore, the formula below should be satisfied after confirming the minimum operating voltage of the load. Supply Internal voltage Minimum operating - > voltage drop of switch voltage of load 2) If the internal resistance of a light emitting diode causes a problem, select a switch without an indicator light (Model A90, A90V). 3) Generally, the internal voltage drop will be greater with a 2wire solid state auto switch than with a reed switch. Take the same precautions as in item (1) as mentioned above. Also, note that a 12 VDC relay is not applicable.

Warning
1. Do not drop or bump.
Do not drop, bump or apply excessive impacts (300m/s2 or greater for reed switches and 1000m/s2 or greater for solid state switches) while handling. Although the body of the switch may not be damaged, the inside of the switch could be damaged and cause a malfunction.
4. Do not wire in conjunction with power lines or high voltage lines.
Wire separately from power lines or high voltage lines, avoiding parallel wiring or wiring in the same conduit with these lines. Control circuits containing auto switches may malfunction due to noise from these lines.
5. Do not allow short circuit of loads.

If the power is turned ON with a load in a short circuited condition, the switch will be instantly damaged because of excess current flow into the switch.
2. Do not carry a cylinder by the auto switch lead wires.
Never carry a cylinder by its lead wires. This may not only cause broken lead wires, but it may cause internal elements of the switch to be damaged by the stress.

D-M9 and all models of PNP output type switches do not have built-in short circuit protection circuits. If loads are short circuited, the switches will be instantly damaged, as in the case of reed switches. Take special care to avoid reverse wiring with the brown [red] power supply line and the black [white] output line on 3-wire type switches.
3. Mount switches using the proper tightening torque.
When a switch is tightened above the torque specification, the mounting screws, or switch may be damaged. On the other hand, tightening below the torque specification may allow the switch to slip out of position. (Refer to page 7 for switch mounting and tightening torque.)
6. Avoid incorrect wiring.

A 24 VDC switch with indicator light has polarity. The brown [red] lead wire is (+), and the blue [black] lead wire is (-). 1) If connections are reversed, the switch will still operate, but the light emitting diode will not light up. Also note that a current greater than the maximum specified one will damage a light emitting diode and make it inoperable. Applicable models: D-A93, A93V
4. Mount a switch at the center of the operating range.
Adjust the mounting position of an auto switch so that the piston stops at the center of the operating range (the range in which a switch is ON). If mounted at the end of the operating range (around the borderline of ON and OFF), operation will be unstable.

When the D-M9 auto switch is used to replace old series auto switch, it may not activate depending on operating condition because of its shorter operating range. Such as * Application where the stop position of actuator may vary and exceed the operating range of the auto switch, for example, pushing, pressing, clamping operation, etc. * Application where the auto switch is used for detecting an intermediate stop position of the actuator. (In this case the detecting time will be reduced. ) In these applications, please set the auto switch to the center of the

1) Even if connections are reversed on a 2-wire type switch, the switch will not be damaged because it is protected by a protection circuit, but it will remain in a normally ON state. But reverse wiring in a short circuit load condition should be avoided to protect the switch from being damaged. 2) Even if (+) and (-) power supply line connections are reversed on a 3-wire type switch, the switch will be protected by a protection circuit. However, if the (+) power supply line is connected to the blue [black] wire and the (-) power supply line is connected to the black [white] wire, the switch will be damaged.
Caution
1. Fix the switch with the appropriate screw installed on the switch body. The switch may be damaged if other screws are used.
Wiring

D-M9 does not have built-in short circuit protection circuit. Be aware that if the power supply connection is reversed (e.g. (+) power supply wire and (-) power supply wire connection is reversed), the switch will be damaged.
Lead wire color changes
Lead wire colors of SMC switches have been changed in order to meet NECA Standard 0402 for production beginning September, 1996 and thereafter. Please refer to the tables provided. Special care should be taken regarding wire polarity during the time that the old colors still coexist with the new colors. 2-wire 3-wire

Warning
1. Avoid repeatedly bending or stretching lead wires.
Broken lead wires will result from repeatedly applying bending stress or stretching force to the lead wires.
2. Be sure to connect the load before power is applied.

3. Confirm proper insulation of wiring.
Be certain that there is no faulty wiring insulation (such as contact with other circuits, ground fault, improper insulation between terminals, etc.). Damage may occur due to excess current flow into a switch.

Operating Environment
Caution
1. When the cable sheath is stripped, confirm the stripping direction. The insulator may be split or damaged depending on the direction.
(D-M9 only)
6. Do not use in an environment where there is excessive impact shock.
When excessive impact (300 m/s2 or more) is applied to a reed switch during operation, the contact point may malfunction and generate a signal momentarily (1 ms or less) or cut off. Consult with SMC regarding the need to use a solid state switch in a specific environment.
7. Do not use in an area where surges are generated.
Recommended tool

When there are units (such as solenoid type lifters, high frequency induction furnaces, motors, etc.) that generate a large amount of surge in the area around an actuator with a solid state auto switch, their proximity or pressure may cause deterioration or damage to the internal circuit of the switch. Avoid sources of surge generation and disorganized lines.
Stripper for a round cable (o2.0) can be used for a 2-wire type cable.
8. Avoid accumulation of iron waste or close contact with magnetic substances.
When a large amount of iron waste such as machining chips or spatter is accumulated, or a magnetic substance (something attracted by a magnet) is brought into close proximity with an auto switch cylinder, it may cause the auto switch to malfunction due to a loss of the magnetic force inside the cylinder.
Operating Environment
Warning
1. Never use in an atmosphere of explosive gases.
The construction of the auto switch is not intended to prevent explosion. Never use in an atmosphere with an explosive gas since this may cause a serious explosion.
Maintenance
2. Do not use in an area where a magnetic field is generated.
The auto switch will malfunction or the magnets inside of an actuator will become demagnetized. (There may be the case where the magnetic field resistant auto switch is usable. Contact us for further details.)
Warning
1. Perform the following maintenance periodically in order to prevent possible danger due to unexpected auto switch malfunction.
1) Securely tighten switch mounting screws. If screws become loose or the mounting position is dislocated, retighten them after readjusting the mounting position. 2) Confirm that there is no damage to the lead wires. To prevent faulty insulation, replace switches or repair lead wires, etc., if damage is discovered. 3) Confirm that the green light on the 2-color display type switch lights up. Confirm that the green LED is ON when stopped at the set position. If the red LED is ON, when stopped at the set position, the mounting position is not appropriate. Readjust the mounting position until the green LED lights up.
3. Do not use in an environment where the auto switch will be continually exposed to water.
The switch satisfies the IEC standard IP67 construction (JIS C 0920: watertight construction). Nevertheless, it should not be used in applications where it is continually exposed to water splash or spray. This may cause deterioration of the insulation or swelling of the potting resin inside switch causing a malfunction.
4. Do not use in an environment with oil or chemicals.
Consult with SMC if the auto switch will be used in an environment laden with coolant, cleaning solvent, various oils or chemicals. If the auto switch is used under these conditions for even a short time, it may be adversely effected by a deterioration of the insulation, a malfunction due to swelling of the potting resin, or hardening of the lead wires.
Other
Warning
1. Consult with SMC concerning water resistance, elasticity of lead wires, usage at welding sites, etc.
5. Do not use in an environment with temperature cycles.
Consult with SMC if the switch is used where there are temperature cycles other than normal temperature changes, as they may adversely affected the switch internally.
