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 167 l ORD311 n ELECTRICAL CHARACTERISTICS Parameter Pull-in Value (PI) Rated value Unit 10〜30 AT 5min AT Contact resistance (CR) 200max mW Breakdown voltage 250min V VDC Insulation resistance 109min W Electrostatic capacitance 0.4max pF Drop-out Value (DO) 10 VA Maximum switching voltage 100（ DC AC ） V Maximum switching current 1.0 A Maximum carry current 0.5 A Contact rating (1) Drop-out Value vs. Pull-in Value (2) Contact resistance (Measurement length: 22mm) 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 168 99 40 50 60 AT 100 120 140 Contact resistance 160 180 mW ORD311 l (4) Insulation resistance (3) Breakdown voltage （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 Pull-in Value 40 50 60 AT 169 l ORD311 n OPERATING CHARACTERISTICS Rated value Unit Operate time 0.3max ms Bounce time 0.3max ms Release time 0.05max ms 13000±2000 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 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 20 30 40 50 0 AT 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 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 20 30 40 Drop-out Value 170 Cumulative frequency percent (%) 99.9 50 AT 11000 12000 13000 Resonant frequency 14000 Hz ORD311 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (2) Lead tensile strength （2.27kg-10sec） 99.9 50 40 30 20 99 Cumulative frequency percent (%) Pull-in Value • Drop-out Value AT 60 PI DO 10 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 2 4 Contact resistance 6 8 10kg Breaking load 0 80 60 CR 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 Rate of change percent 30 CR 20 DO 10 PI 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 171 l ORD311 (2) Temperature cycle (3) Temperature and humidity cycle -10℃〜+65℃ 80％〜98％ (-55℃〜+125 ℃) AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI DO 40 30 20 DO 0 0 mW 100 mW 100 80 60 PI 10 Contact resistance Contact resistance 10 50 CR Before test 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 80 CR Before test 172 Contact resistance Contact resistance 10 60 After test After test 80 60 CR Before test After test ORD311 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 60 0 10 20 30 40 50 60 AT Pull-in Value CR 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 60 CR Before test After test 173 l ORD311 n LIFE EXPECTANCY DATA: ORD311 Load conditions Voltage: 5VDC Current: 100mA 10mA , 20mA Load: Resistive load Cumulative failure rate （%） 99.9 No failure 90 70 50 30 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.
