ORD211

J2R0011-38-21 l REED SWITCH ORD211 Ultra-miniature n GENERAL DESCRIPTION The ORD211 is a small single-contact reed switch designed for general control of low-level loads less than 24 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) f0.4 MAX f2.0 MAX 10.0 35.7±0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances 39 l ORD211 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∼40 5min 100max 150min 109min 0.2max 1.0 24 ( DC ) AC 0.1 0.3 Unit AT AT mW VDC W pF VA V A A (1) Drop-out Value vs. Pull-in Value (2) Contact resistance 99.9 Cumulative frequency percent (%) (Measurement length: 22mm) AT 50 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 40 60 80 100 mW Drop-out Value 40 30 20 10 0 10 20 30 40 50 AT Pull-in Value Contact resistance 40 ORD211 l (3) Breakdown voltage (4) Insulation resistance 99.9 Cumulative frequency percent (%) 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 1010 W (DC 100V) DC：V 400 Breakdown voltage 300 200 100 0 10 20 30 Pull-in Value 40 50 AT 1011 1012 1013 1014 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 41 l ORD211 n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 0.3max 0.3max 0.05max 7500±500 500 Unit ms ms ms Hz Hz (1) Operate time (25 Hz: 100AT energized) (2) Bounce time 99.9 ms 0.5 (25Hz: 100AT energized) 99 Cumulative frequency percent (%) 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0.4 Operate time 0.3 0.2 0.1 0 10 20 30 40 50 AT 0 0.1 0.2 0.3 0.4 ms Pull-in Value Bounce time (3) Release time (4) Resonant frequency 99.9 99 Cumulative frequency percent (%) AT (25Hz: 100AT energized) µs 15 95 90 80 70 60 50 40 30 20 10 5 1 0.1 7000 7500 8000 Resonant frequency Hz Release time 10 5 0 10 20 30 40 50 Drop-out Value 42 ORD211 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (Measurement length: 22mm) (2) Lead tensile strength 99.9 99 Cumulative frequency percent (%) AT 60 Pull-in Value・Drop-out Value 50 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 2 4 6 8 10kg 40 30 PI 20 DO 10 0 Contact resistance Breaking load mW 80 CR 60 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 CR 30 Rate of change percent 20 DO PI 10 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 43 l ORD211 (2) Temperature cycle (-55℃ to 125℃) (3) Temperature and humidity cycle -10℃ to 65℃ 80% to 98% AT 60 AT 60 Pull-in Value・Drop-out Value Pull-in Value・Drop-out Value 50 50 40 30 PI 20 DO 10 40 30 PI 20 DO 10 0 0 Contact resistance Contact resistance mW 80 CR mW 80 CR 60 60 40 Before test After test 40 Before test After test (4) High temperature storage test (+125℃-500H) AT 60 (5) Low temperature storage test (-40℃-500H) AT 60 Pull-in Value・Drop-out Value Pull-in Value・Drop-out Value 50 50 40 40 30 PI 20 DO 10 30 PI 20 DO 10 0 0 Contact resistance Contact resistance mW 80 CR mW 80 CR 60 60 40 40 Before test After test Before test After test 44 ORD211 l (6) Shock test 1) Electrical characteristics (30G: 11ms) AT 60 2) Misoperation area (open→close) G 1500 Pull-in Value・Drop-out Value 50 40 30 PI 20 DO 10 Acceleration 1000 Misoperation area 500 0 Contact resistance mW 80 CR 60 0 10 20 30 40 50 60 AT Pull-in Value 40 Before test After test (7) Vibration test (20G: 10∼1000Hz) AT 60 Pull-in Value・Drop-out Value 50 40 30 PI 20 DO 10 0 Contact resistance mW 80 CR 60 40 Before test After test 45 l ORD211 n LIFE EXPECTANCY DATA: ORD211 (%) 99.9 Cumulative Cumulative failure rate 90 70 50 30 10 5 No failure 5mA 1mA 100µA Load conditions Voltage: 5VDC Current: 100 µA, 1 mA, 5 mA Load: Resistive load 1 0.1 0 23 5 7 105 23 5 7 106 23 5 7 107 23 5 7 108 Number of operations * Arrow indicates number of operations where test was completed.
