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) MAX f2.0 f0.4 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) Rated value Unit 10∼40 AT 5min AT Contact resistance (CR) 100max mW Breakdown voltage 150min VDC Insulation resistance 109min W Electrostatic capacitance 0.2max pF 1.0 VA Drop-out Value (DO) Contact rating 24 ( DC AC ) Maximum switching voltage V Maximum switching current 0.1 A Maximum carry current 0.3 A (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 40 Pull-in Value 40 99 50 AT 40 60 80 100 Contact resistance mW ORD211 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 AT Pull-in Value 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 1010 1011 1012 1013 1014 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 41 l ORD211 n OPERATING CHARACTERISTICS Parameter Rated value Unit Operate time 0.3max ms Bounce time 0.3max ms Release time 0.05max ms 7500±500 Hz 500 Hz Resonant frequency Maximum operating frequency (1) Operate time (2) Bounce time (25 Hz: 100AT energized) (25Hz: 100AT energized) 99.9 ms 0.5 Cumulative frequency percent (%) 99 Operate time 0.4 0.3 0.2 0.1 0 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 (3) Release time (4) Resonant frequency 99.9 Cumulative frequency percent (%) 99 (25Hz: 100AT energized) Release time µs 15 10 5 0 10 20 30 40 Drop-out Value 42 50 AT 95 90 80 70 60 50 40 30 20 10 5 1 0.1 7000 7500 8000 Resonant frequency Hz ORD211 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (2) Lead tensile strength (Measurement length: 22mm) 99.9 AT 99 Cumulative frequency percent (%) Pull-in Value・Drop-out Value 60 50 40 30 PI 20 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 mW 80 60 CR 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ CR 40 Rate of change percent 30 DO 20 PI 10 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 43 l ORD211 (2) Temperature cycle (3) Temperature and humidity cycle -10℃ to 65℃ 80% to 98% (-55℃ to 125℃) AT 60 Pull-in Value・Drop-out Value Pull-in Value・Drop-out Value AT 60 50 40 30 PI 20 DO 40 30 PI 20 DO 10 0 0 mW 80 mW 80 60 Contact resistance Contact resistance 10 50 CR 40 Before test 60 CR 40 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 PI 20 DO 40 30 PI 20 DO 0 0 mW 80 mW 80 CR 40 CR 60 40 Before test 44 50 10 Contact resistance Contact resistance 10 60 After test After test Before test After test ORD211 l (6) Shock test 1) Electrical characteristics 2) Misoperation area (open→close) (30G: 11ms) AT 60 G 50 40 Acceleration Pull-in Value・Drop-out Value 1500 30 PI 20 DO 1000 Misoperation area 10 500 Contact resistance 0 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) Pull-in Value・Drop-out Value AT 60 50 40 30 PI 20 DO 10 Contact resistance 0 mW 80 CR 60 40 Before test After test 45 l ORD211 n LIFE EXPECTANCY DATA: ORD211 Load conditions Voltage: 5VDC Current: 100 µA, 1 mA, 5 mA Load: Resistive load Cumulative failure rate (%) 99.9 90 70 50 30 No failure 1mA 5mA 100µA 10 5 1 0.1 0 2 3 5 7 105 2 3 5 7 106 2 3 Number of operations 5 7 107 2 3 5 7 108 * Arrow indicates number of operations where test was completed.
