| J2R0012-38-22 REED SWITCH ORD311 Super Ultra Miniature Long Life n GENERAL DESCRIPTION The ORD311 is a small single-contact reed switch designed for general control of medium level loads less than 100 V. The contacts are sealed within the glass tube with inert gas to maintain contact reliability. n FEATURES (1) Reed switches are hermetically sealed within a glass tube with inert gas and do not receive any influence from the external atmospheric environment. (2) Quick response (3) The structure comprises the operating parts and electrical circuits arranged coaxially. Reed switches are suited to applications in radio frequency operation. (4) Reed switches are compact and light weight. (5) Superior corrosion resistance and wear resistance of the contacts assures stable switching operation and long life. (6) With a permanent magnet installed, reed switches economically and easily become proximity switches. n EXTERNAL DIMENSIONS (Unit: mm) f0.33 MAX f1.8 MAX 7.0 35.8 0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances l ORD311 n ELECTRICAL CHARACTERISTICS Parameter Pull-in Value (PI) Drop-out Value (DO) Contact resistance (CR) Breakdown voltage Insulation resistance Electrostatic capacitance Contact rating Maximum switching voltage Maximum switching current Maximum carry current Rated value 10 30 5min 200max 250min 109min 0.4max 10 100 DC AC Unit AT AT mW V VDC W pF VA V A A 1.0 0.5 99.9 (Measurement length: 22mm) Cumulative frequency percent (%) AT 50 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 100 120 140 160 180 mW Drop-out Value 40 30 20 10 0 10 20 30 Pull-in Value 40 50 60 AT Contact resistance ORD311 l (3) Breakdown voltage (4) Insulation resistance 99.9 Cumulative frequency percent (%) DC 100V 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 10 11 12 13 14 DC V 400 Breakdown voltage 300 200 100 0 10 20 30 Pull-in Value 40 50 AT 10 10 10 10 W Insulation resistance (5) Electrostatic capacitance 1MHz pF Electrostatic capacitance 0.4 0.3 0.2 0.1 0 10 20 30 Pull-in Value 40 50 60 AT l ORD311 n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 0.3max 0.3max 0.05max 13000 2000 500 Unit ms ms ms Hz Hz (1) Operate time (25Hz: 100AT energized) (2) Bounce time (25Hz: 100AT energized) 99.9 Cumulative frequency percent (%) ms 0.5 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 0.1 0.2 0.3 0.4 ms 0.4 Operate time 0.3 0.2 0.1 0 10 20 30 Pull-in Value 40 50 AT Bounce time (3) Release time (4) Resonant frequency 99.9 Cumulative frequency percent (%) 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 (25Hz: 100AT energized) ms 15 Release time 10 5 0 10 20 30 40 50 AT 11000 12000 13000 14000 Hz Drop-out Value Resonant frequency ORD311 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) 2.27kg-10sec (2) Lead tensile strength 99.9 AT 60 Cumulative frequency percent (%) 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 2 4 6 8 10kg Breaking load Pull-in Value * Drop-out Value 50 40 30 20 PI DO 10 0 Contact resistance 80 60 CR 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics 40 30 CR Rate of change percent 20 DO 10 PI 0 10 20 30 40 20 0 20 40 Temperature 60 80 100 120 l ORD311 (2) Temperature cycle (-55 AT 60 Pull-in Value * Drop-out Value Pull-in Value * Drop-out Value +125 ) (3) Temperature and humidity cycle -10 80 AT 60 +65 98 50 50 40 40 30 PI DO 30 PI DO 20 20 10 10 0 Contact resistance Contact resistance mW 100 0 mW 100 80 CR 80 CR 60 60 Before test After test Before test After test (4) High temperature storage test (+125 -500H) AT 60 Pull-in Value * Drop-out Value Pull-in Value * Drop-out Value (5) Low temperature storage test -500H) AT 60 50 50 40 40 30 PI DO 30 PI DO 20 20 10 10 0 Contact resistance Contact resistance mW 100 0 mW 100 80 CR 80 CR 60 60 Before test After test Before test After test ORD311 l (6) Shock test 1) Electrical characteristics (30G: 11ms) AT 60 Pull-in Value * Drop-out Value 2) Misoperation area (open close) G 1500 50 40 30 PI DO Acceleration 1000 Misoperation area 20 10 500 0 Contact resistance mW 100 80 CR 0 10 20 30 40 50 60 AT Pull-in Value 60 Before test After test (7) Vibration test (20G: 10 1000Hz) AT 60 Pull-in Value * Drop-out Value 50 40 30 PI DO 20 10 0 Contact resistance mW 100 80 CR 60 Before test After test l ORD311 n LIFE EXPECTANCY DATA: ORD311 % 99.9 90 70 50 30 10 5 No failure 20mA 10mA 100mA Load conditions Voltage: 5VDC Current: 100mA 10mA , 20mA Load: Resistive load Cumulative failure rate 1 0.1 0 23 5 7 106 23 5 7 107 23 5 7 108 23 5 7 109 Number of operations * Arrow indicates number of operations where test was completed. % 99.9 90 70 50 30 10 5 No failure Load conditions Voltage: 12 VDC Current: 5mA, 10mA, 100mA Load: Resistive load Cumulative failure rate 100mA 10mA 5mA 1 0.1 0 23 5 7 106 23 5 7 107 23 5 7 108 23 5 7 109 Number of operations * Arrow indicates number of operations where test was completed.
