ORD312

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 ORD312 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 100max 250min 109min 0.3max 30 200DC 100AC 0.5 1.0 Unit AT AT mW VDC V W pF VA V A A (1) Drop-out Value vs. Pull-in Value (2) Contact resistance 99.9 (Measurement length: 32mm) 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 176 ORD312 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 AT 177 l ORD312 n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 0.4max 0.3max 0.05max 5900±400 500 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 5500 6000 6500 Hz Drop-out Value Resonant frequency 178 ORD312 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 PI DO 20 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 10 DO PI 0 −10 −20 −30 −40 −20 0 20 40 Temperature 60 80 100 120 140 ℃ 179 l ORD312 (2) Temperature cycle (-55℃∼+125 ℃) AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value (3) Temperature and humidity cycle -10℃∼+65℃ 80％∼98％ AT 60 50 50 40 40 30 PI DO 30 PI DO 20 20 10 10 0 Contact resistance mW 100 0 Contact resistance mW 100 80 CR 80 CR 60 Before test After test 60 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 AT 60 (5) Low temperature storage test (-40℃-500H) 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 Before test After test 60 Before test After test 180 ORD312 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 CR 80 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 CR 80 60 Before test After test 181 l ORD312 n LIFE EXPECTANCY DATA: ORD312 （%） 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: 12VDC 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.
