g-156 safety sensors / components characteristics note: 1. the above values are initial values. 2. the degree of protection is tested using t he method specified by the standard (en60947- 5-1). confirm that sealing properties ar e suffi- cient for the operating conditions and environment beforehand. although the switch box is protected from dust or water penetrat ion, do not use the d4nl in places where foreign material may penetrate through the key hole on the head, otherwise switch damage or ma l- functioning may occur. 3. the durability is for an ambient temperature of 5 c to 35 c and an ambient humidity of 40% to 70%. for more details, consult your om- ron representative. 4. if the ambient temperature is greater than 35 c, do not pass the 3-a, 250-vac load through more than 2 circuits. 5. these figures are minimum r equirements for safe operation. 6. this figure is based on the gs-et-19 evaluation method. 7. this value will vary with the switching frequency, environment, and reliability level. confirm that correct operation is possib le with the actual load beforehand. degree of protection (see note 2) ip67 (en60947-5-1) (this applies for the switch only. the degree of protection for the key hole is ip00.) durability (see note 3) mechanical 1,000,000 operations min. electrical 500,000 operations min. for a resistive load of 3 a at 250 vac (see note 4) operating speed 0.05 to 0.5 m/s operating frequency 30 operations/minute max. rated frequency 50/60 hz contact gap 2 x 2 mm min direct opening force (see note 5) 60 n min.

g-157 d4nl d4nl connections indicator internal circuit diagram circuit connection example terminals 12 and 41 are connected internally and so connect termi- nals 11 and 42 for safety-circuit input. (gs-et-19) connect terminals 21 and 22 and terminals 51 and 52 in series when using as safety-circuit i nput (redundancy circuit for terminals 11 and 12 and terminals 41 and 42 above). connect the terminals individually when using as auxiliary -circuit input (e.g., terminals 21 and 22 for safety-door open/clos ed monitoring and terminals 51 and 52 for monitoring the lock status). in the connection example on the right, terminals 21 and 22 and terminals 51 and 52 are used as auxiliary-circuit input. direct opening contacts used as safe ty-circuit input are indicated with the mark. terminals 11 and 12 and terminals 21 and 22 are direct opening contacts. connect the indicators in parallel to the auxiliary circuits or termi- nals e1 and e2. if an indicator is connected in paral lel to a direct opening contact, when the indicator breaks, a shor t-circuit current will be generated, possibly resulting in an installation malfunction. do not switch standard loads for more than 2 circuits at the same time. otherwise, the level of insulation may decrease. the 24-vdc solenoid has polarity. be sure to connect terminals with the correct polarity. d r r led z 10 to 115 vac/vdc constant-current diode 42 11 21 33 e1 (+) o1 o2 12 41 51 52 22 34 e2 ( ? ) indicator (orange) safety circuit auxiliary circuit auxiliary circuit auxiliary circuit f502-en2-04.book seite 157 di enstag, 26. juli 2005 5:48 17
g-158 safety sensors / components operation method operation principles nomenclature structure note: terminal numbers vary with the model. mechanical lock models when the operation key is inserted, it is locked by the lock spring. the door will stay locked even if there is a power interruption. the solenoid is released only when the lock is turned on. solenoid lock models if the solenoid is off, the door will not be locked when the operation key is inserted. this means that the door can be opened and closed easily when replacing work- pieces or parts. the door is locked only when the solenoid is turned on. this means that the door will be unlocked if there is a power interruption and so this model cannot be used in sys- tems that would maintain a hazardous state (e.g., systems requiring toxic gases, high temperatures, or gears that would continue to turn due to inertia). solenoid operation key lock plate spring off off on solenoid operation key lock plate spring off plunger off on special release key the head can be mounted in 3 directions. two conduits (horizontal and vertical) back-mounting is also possible. operation key hole terminal 42 terminal 41 shorting pin (12-41) terminal 12 terminal 11 door open/closed detection switch terminal 21 terminal 22 terminal 31/33 terminal 32/34 release key conduit opening (vertical) terminal 51/53 terminal 52/54 conduit opening (horizontal) lock monitor switch terminal 02 indicator terminal 01 terminal e1 (+ ) terminal e2 ( ? ) solenoid unlock lock unlock lock standard release key (bottom view) special release key (bottom view) f502-en2-04.book seite 158 di enstag, 26. juli 2005 5:48 17

g-165 d4nl d4nl precautions !caution do not insert the operation key with the door open. the machine may operate and damage may result. !caution do not use metal connectors or c onduits with this switch. damage to the broken conduit hole may cause electric shock. !caution change the head direction after changing the release key to the unlock position. do not change the head direction with the cov- er removed. failure to observe these points may result in switch malfunction or damage. holding force do not apply a force exceeding the specified holding force. doing so may break the switch and the machine may continue to operate. either install another locking com ponent (e.g., a stop) in addition to the switch, or use a warning sti cker or an indicator showing the lock status so that a force ex ceeding the specified holding force is not applied. safety precautions the switch contacts can be us ed for either standard loads or microloads. once a contact has been used to switch a standard load, however, it cannot be used for a load of a smaller capacity. doing so may result in roughening of the contact surface and con- tact reliability may be lost. turn off the power before disassembling the switch or touching any internal parts. not doing so may result in electric shock. mount the operation key in a location where it will not come in con- tact with users when the door is opened or closed. otherwise, injury may result. do not impose excessive force on the operation key when it is inserted into the switch or drop the switch with the operation key inserted. otherwise, the operation key may be deformed or the switch may be broken. observe the specified insertion radius for the operation key and insert it in a direction perpendicular to the key hole. do not use the switch in starting ci rcuits. (use for safety confirma- tion signals.) when using the switch in emergenc y-stop circuits or other safety circuits that have a direct impact on human lives, operate the nc contacts that have a direct opening mechanism in direct opening mode. for safety purposes, prevent easy removal by, for example, mounting the switch and operation key with one-way screws or attaching a protective cover and warning label. in order to prevent short-circui t damage to the switch, connect a fuse to the switch in series. use a fuse with a breaking current of 1.5 to 2 times the rated current. to conform to en ratings, use a iec269-compliant 10-a fuse type gi or gg . turn the power off when wiring. after wiring is completed, be sure to mount the cover before use. in order to prevent burning due to overvoltage, insert a protective fuse in the solenoid circuits. do not use the switch where explosive gas, flammable gas, or any other dangerous gas may be present. ensure that the load current does not exceed the rated current. be sure to wire the terminals correctly. be sure to evaluate the switch under actual operating conditions after installation. do not drop the package or the product. do not disassemble inter- nal parts. release key the release key is used to unlock the switch in case of emergency or if the power supply to the switch stops. if the release key setting is cha nged from lock to unlock using an appropriate tool, the lock will be released and the safety door can be opened (mechanical lock models only). after setting the release key to unlock in order to, for example, change the head direction or perform maintenance, be sure to return it to lock setting before resuming operation. when the switch is used for the door of a machine room to ensure the safety of people performing adjustment work inside, if the release key is set to unlock, the door will not be locked when the door is closed and no power wi ll be supplied to the equipment. do not use the release key to start or stop machines. the auxiliary lock must only be released by authorized personnel. do not impose a force exceeding 1 nm on the release key screws. the release key may be damaged and may not operated properly. to prevent the release key from being used by unauthorized per- sonnel, set it to lock and seal it with seal wax. mounting do not use the switch as a stopper. to prevent the door from com- ing into contact with the flange of the operation key, be sure to mount the switch with a stopper as shown above. when the switch is used for a hinged door at a location near to the hinged side, where the operation key?s insertion radius is compar- atively small, if an attempt is made to open the door beyond the lock position, the force imposed will be much larger than for loca- tions far from the hinged side, and the lock may be damaged. solenoid lock models the solenoid lock locks the door only when power is supplied to the solenoid. therefore, the door will be unlocked if the power supply to the solenoid stops. therefore, do not use solenoid lock models for machines that may be operating and dangerous even after the machine stops operating. unlock lock switch operation key door stopper set zone (0.5 to 3 mm) f502-en2-04.book seite 165 di enstag, 26. juli 2005 5:48 17
g-166 safety sensors / components correct use operating environment this switch is for indoor use only. do not use it outdoors. other- wise, it may malfunction. do not use the switch in the following locations: locations subject to severe temperature changes locations subject to high hum idity levels or condensation locations subject to severe shocks or vibrations locations where the switch may come in contact with metal dust, oil, or chemicals locations subject to thinner, detergent, or other solvents. although the switch itself is protected from dust or water penetra- tion, ensure that foreign material does not penetrate through the key hole on the head, otherwise switch damage or malfunctioning may occur. do not use the switch submerged in oil or water, or in locations continuously subject to splashes of oil or water. doing so may result in oil or water entering the switch interior. (the ip67 degree of pro- tection specification for the switch pertains to the amount of water penetration after the switch is submerged in water for a certain period of time.) life expectancy the life expectancy of the switch w ill vary with the switching condi- tions. before applying the switch, test it under actual operating con- ditions and be sure to use it at a switching frequency that will not lower its performance. operation key use the designated omron operation key with the switch. using another operation key may result in switch damage. do not impose excessive force on the operation key when it is inserted into the switch or drop the switch with the operation key inserted. otherwise, the operation key may be deformed or the switch may be broken. mounting tightening torque be sure to tighten each screw of the switch properly. loose screws may result in malfunction. switch and operation key mounting mount the switch and operation key securely to the applicable tightening torque with m4 screws. ] if the switch is back-mounted, the release key can only be oper- ated from the bottom and the indicator cannot be used. use the designated omron operation key with the switch. using another operation key may result in switch damage. ensure that the alignment offset between the operation key and the key hole does not exceed 1 mm. head direction by removing the four screws of the head, the mounting direction of the head can be changed. the head can be mounted in four direc- tions. ensure that no foreign matter penetrates the interior of the switch. securing the door when the door is closed (with the operation key inserted), it may be pulled beyond the set zone because of, for example, the door?s weight, or the door cushion rubber. also, if a load is applied to the operation key, the door may fail to unlock properly. use hooks to ensure that the door stays within the set zone (0.5 to 3 mm). type tightening torque terminal screw 0.59 to 0.78 nm cover mounting screw 0.49 to 0.69 nm head mounting screw 0.49 to 0.59 nm operation key mounting screw 2.35 to 2.75 nm switch mounting screw 0.49 to 0.69 nm connector 1.77 to 2.16 nm cap screw 1.27 to 1.67 nm applying weight dropping d4ds-k1/-k2 (horizontal/vertical mounting) d4ds-k3 (adjustable mounting: horizontal) d4ds-k5 (adjustable mounting: vertical) 40 0.1 two, m4 15 0.1 two, m4 mounting hole dimensions for switch mounting hole dimensions for operation key three, m4 79 0.1 32 0.1 55 0.1 41 0.1 or, 43 0.1 two, m4 operation key set zone (0.5 to 3 mm) f502-en2-04.book seite 166 di enstag, 26. juli 2005 5:48 17
g-167 d4nl d4nl wiring wiring precautions when connecting to the terminals via insulating tube and m3.5 crimp terminals, cross the crimp terminals as shown above so that they do not rise up onto the case or the cover. applicable lead wire size: awg20 to awg18 (0.5 to 0.75mm 2 ). when connecting lead wires directly to terminals, perform wiring securely so that there are no loose wire strands. do not push crimp terminals into gaps in the case interior. doing so may cause damage or deformation of the case. use lead wires of an appropriate length. not doing so may cause the cover to rise. use crimp terminals not more than 0.5 mm in thickness. otherwise, they will interfere with other components inside the case. the crimp terminals shown below are not more than 0.5 mm thick. conduit opening connect a recommended connector to the opening of the conduit and tighten the connector to the proper torque. the case may be damaged if an excessive tightening torque is applied. in order to ensure ip67 degree of protection, wrap sealing tape around the conduit end of the connector. be sure that the outer diameter of the cable connected to the con- nector is correct. attach and tighten a conduit cap to the unused conduit opening when wiring. the conduit cap is provided with the switch. recommended connectors use a connector with a screw section not exceeding 11 mm, other- wise the screws will protrude into the case interior. the connectors given in the following table have connectors with screw sections not exceeding 11 mm. use the following connectors to ensure conformance to ip67. use lapp connectors together with seal packing (jpk-16, gp-13.5, or gpm20), and tighten with the applicable torque. seal packing is sold separately. maintenance and repairs the user must not perform repai rs or maintenance. contact the machine manufacturer if repai rs or maintenance are required. storage do not store the switch in locations where harmful gases (e.g., h 2 s, so 2 , nh 3 , hno 3 , or cl 2 ) or dust are present, or in locations subject to high humidity levels. miscellaneous do not touch the solenoid. the temperature of the solenoid increases when current is passed. in conditions requiring greater ri gidity, sealing performance, and oil resistance, use omron?s d4bl. perform regular inspections. manufacturer model j.s.t. fv0.5-3.7 11 22 21 34 33 12 l l f b d dz t: 0.5 mm dz dia.: 3.7 mm d dia.: 2.9 mm b: 6.6 mm l: 19 mm f: 7.7 mm i : 8.0 mm terminal screw crimp terminal size manufacturer model applicable cable diameter g 1 / 2 lapp st-pf1/2 5380-1002 6.0 to 12.0 mm ohm denki oa-w1609 7.0 to 9.0 mm oa-w1611 9.0 to 11.0 mm pg13.5 lapp s-13.5 5301-5030 5.0 to 12.0 mm m20 lapp st-m20 * 1.5 5311-1020 7.0 to 13.0 mm f502-en2-04.book seite 167 di enstag, 26. juli 2005 5:48 17
