ORD2211

J2R0017-38-21 l O D2211 R REED SWITCH ORD2211 Lamp Load n GENERAL DESCRIPTION The ORD2211 is a single-contact reed switch designed for direct opening or closing lamps of 12 V - 3.4 W. 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) f0.6 MAX f2.8 MAX 16.5 44.1±0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances 79 l ORD2211 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 20∼60 8min 100max 200min (PI≧20) 109min 0.3max 50 (12V-3.4W lamp) DC 100（ ） AC Unit AT AT mW VDC W pF VA V A A 0.5 (Inrush 3A) 2.5 (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 40 60 80 100 mW Drop-out Value 40 30 20 10 0 10 20 30 40 50 60 Pull-in Value AT Contact resistance 80  ORD2211 l (3) Breakdown voltage (4) Insulation resistance 99.9 （DC 100V） Cumulative frequency percent (%) 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 1010 1011 1012 1013 1014 DC：V 400 Breakdown voltage 300 200 100 0 10 20 30 40 50 Pull-in Value 60 AT W Insulation resistance (5) Electrostatic capacitance (1MHz) pF 0.4 Electrostatic capacitance 0.3 0.2 0.1 0 10 20 30 40 50 60 Pull-in Value AT 81 l ORD2211 n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 0.6max 0.4max 0.05max 4600±500 500 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 40 50 Pull-in Value 60 AT Bounce time (3) Release time (4) Resonant frequency 99.9 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 (25Hz: 100AT energized) ms 15 10 5 0 10 20 30 40 50 AT Cumulative frequency percent (%) Release time 4100 4600 5100 Hz Drop-out Value Resonant frequency 82  ORD2211 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) （2.27kg-10sec） AT 60 Cumulative frequency percent (%) Pull-in Value • Drop-out Value 99.9 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 2 4 6 8 10kg (2) Lead tensile strength 50 40 PI 30 DO 20 10 0 Contact resistance Breaking load mW 80 60 CR 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 CR 30 Rate of change percent 20 10 0 DO PI −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 83 l ORD2211 (2) Temperature cycle (-55℃ to 125 ℃) AT 60 (3) Temperature and humidity cycle -10℃ to 65 ℃ 80% to 98% AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value 50 50 40 PI 30 40 PI 30 20 DO 20 DO 10 10 0 mW 80 0 mW 80 Contact resistance Contact resistance 60 CR 40 Before test After test 60 CR 40 Before test After test (4) High temperature storage test (+125℃-500H) (5) Low temperature storage test (-40℃-500H) AT 60 Pull-in Value • Drop-out Value AT 60 Pull-in Value • Drop-out Value 50 50 40 PI 30 40 PI 30 20 DO 20 DO 10 10 0 Contact resistance 0 mW 80 Contact resistance mW 80 60 CR 40 Before test After test 60 CR 40 Before test After test 84  ORD2211 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 Acceleration PI 1000 Misoperation area 20 DO 10 500 0 mW 80 Contact resistance 60 CR 40 0 10 20 30 40 50 60 AT Pull-in Value Before test After test (7) Vibration test (20G: 10∼1000Hz) AT 60 Pull-in Value • Drop-out Value 50 40 PI 30 20 DO 10 0 mW 80 Contact resistance 60 CR 40 Before test After test 85 l ORD2211 n LIFE EXPECTANCY DATA: ORD2211 （%） 99.9 Cumulative failure rate Load conditions Voltage: 13, 14, 16：VDC Current: 12V-3.4W Lam p 90 70 50 30 10 5 1 16V 14V 13V 0.1 0 23 5 7 104 23 57 105 23 57 106 23 57 107 Number of operations （%） 99.9 Cumulative failure rate Load conditions Voltage: 50VDC Current: 1A Load: Resistive load 90 70 50 30 10 5 1 No failure 0.1 0 23 5 7 104 23 57 105 23 57 106 23 57 107 Number of operations * Arrow indicates number of operations where test was completed. （%） 99.9 Cumulative failure rate Load conditions Voltage: 6VDC Current: 10mA, 50mA Load: Resistive load 90 70 50 30 10 5 1 No failure 50mA 10mA 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. 86
