J2R0013-38-21 REED SWITCH ORD312 High Power Long Life n GENERAL DESCRIPTION The ORD312 is a small single-contact reed switch designed for general control of medium level loads less than 200 V. The contacts are sealed within the glass tube with inert gas to maintain contact reliability. n FEATURES (1) Reed contacts 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) f0.5 MAX f2.0 MAX 12.0 44.3±0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances 175 l ORD312 n ELECTRICAL CHARACTERISTICS Parameter Pull-in Value (PI) Rated value Unit 10〜30 AT 5min AT Contact resistance (CR) 100max mW Breakdown voltage 250min VDC V Insulation resistance 109min W Electrostatic capacitance 0.3max pF Drop-out Value (DO) 30 VA Maximum switching voltage 200DC 100AC V Maximum switching current 0.5 A Maximum carry current 1.0 A Contact rating (2) Contact resistance (1) Drop-out Value vs. Pull-in Value (Measurement length: 32mm) 99.9 Cumulative frequency percent (%) Drop-out Value AT 50 40 30 20 10 0 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 20 30 Pull-in Value 176 99 40 50 60 AT 100 120 140 Contact resistance 160 180 mW ORD312 l (3) Breakdown voltage (4) Insulation resistance （DC 100V） Cumulative frequency percent (%) 99.9 Breakdown voltage DC：V 400 300 200 100 0 10 20 30 40 50 Pull-in Value AT 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 10 11 10 12 10 13 10 14 10 W Insulation resistance (5) Electrostatic capacitance （1MHz） Electrostatic capacitance pF 0.4 0.3 0.2 0.1 0 10 20 30 40 50 AT Pull-in Value 177 l ORD312 n OPERATING CHARACTERISTICS Rated value Unit Operate time 0.4max ms Bounce time 0.3max ms Release time 0.05max ms 5900±400 Hz 500 Hz Parameter Resonant frequency Maximum operating frequency (2) Bounce time (1) Operate time (25Hz: 100AT energized) (25Hz: 100AT energized) 99.9 Cumulative frequency percent (%) ms 0.5 Operate time 0.4 0.3 0.2 0.1 0 10 20 30 40 50 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 AT 0 0.1 Pull-in Value 0.2 0.3 0.4 ms Bounce time (4) Resonant frequency (3) Release time Release time (25Hz: 100AT energized) ms 15 10 5 0 10 20 30 40 Drop-out Value 178 50 Cumulative frequency percent (%) 99.9 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 AT 5500 6000 6500 Resonant frequency Hz ORD312 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (2) Lead tensile strength （2.27kg-10sec） 99.9 Cumulative frequency percent (%) Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI DO 10 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 2 Contact resistance 4 6 8 10kg Breaking load 0 80 60 CR 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 30 Rate of change percent CR 20 10 DO PI 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 140 ℃ Temperature 179 l ORD312 (2) Temperature cycle (3) Temperature and humidity cycle -10℃〜+65℃ 80％〜98％ (-55℃〜+125 ℃) Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI DO 50 40 30 20 10 0 0 mW 100 mW 100 80 CR 60 Before test PI DO 10 Contact resistance Contact resistance Pull-in Value • Drop-out Value AT 60 80 CR 60 After test Before test (4) High temperature storage test (5) Low temperature storage test (-40℃-500H) (+125℃-500H) AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI 50 40 30 20 PI DO DO 10 0 0 mW 100 mW 100 CR 60 Before test 180 Contact resistance Contact resistance 10 80 After test After test 80 CR 60 Before test After test ORD312 l (6) Shock test 1) Electrical characteristics 2) Misoperation area (open→close) (30G: 11ms) G 1500 50 40 Acceleration Pull-in Value • Drop-out Value AT 60 30 20 PI 1000 Misoperation area DO 10 500 Contact resistance 0 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) Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI DO 10 Contact resistance 0 mW 100 80 CR 60 Before test After test 181 l ORD312 n LIFE EXPECTANCY DATA: ORD312 Load conditions Voltage: 5VDC Current: 100mA, 10mA, 20mA Load: Resistive load Cumulative failure rate （%） 99.9 90 70 50 30 No failure 20mA 10mA 100mA 10 5 1 0.1 0 2 3 5 7 106 2 3 5 7 107 2 3 5 7 108 2 3 5 7 109 Number of operations * Arrow indicates number of operations where test was completed.
