ORD228VL

J2R0015-41-31 l O D228VL R REED SWITCH ORD228VL Miniature High-performance n GENERAL DESCRIPTION The ORD228VL 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 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 f2.2 MAX 14.0 44.3±0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances 71 l ORD228VL 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∼50 5min 100max 200 min (PI≧20) 150 min (PI＜20) 109min 0.3max 10 DC 100（ ） AC Unit AT AT mW VDC VDC W pF VA V A A 0.5 1.0 (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 40 Drop-out Value 30 20 10 0 10 20 30 40 50 AT Pull-in Value Contact resistance 72  ORD228VL 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 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 0.4 Electrostatic capacitance 0.3 0.2 0.1 0 10 20 30 Pull-in Value 40 50 AT 73 l ORD228VL n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 0.4max 0.3max 0.05max 5000±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 4500 5000 5500 Hz Drop-out Value Resonant frequency 74  ORD228VL 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 20 DO 10 0 Contact resistance mW 80 CR Breaking load 60 40 Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 CR 30 Rate of change percent 20 DO 10 PI 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 75 l ORD228VL (2) Temperature cycle (-55℃ to 125 ℃) AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value (3) Temperature and humidity cycle -10℃ to 65 ℃ 80% to 98% AT 60 50 50 40 PI 40 PI 30 30 20 DO 10 20 DO 10 0 mW 80 CR 0 mW 80 Contact resistance 60 Contact resistance 60 CR 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 30 PI 20 DO 10 20 DO 10 0 0 Contact resistance Contact resistance mW 80 mW 80 60 CR 60 CR 40 40 Before test After test Before test After test 76  ORD228VL l (6) Shock test 1) Electrical characteristics (30G: 11ms) 2) Misoperation area (open→close) AT 60 Pull-in Value • Drop-out Value G 1500 50 40 Acceleration 30 PI 1000 20 DO 10 Misoperation area 500 0 mW 80 CR Contact resistance 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 mW 80 CR Contact resistance 60 40 Before test After test 77 l ORD228VL n LIFE EXPECTANCY DATA: ORD228VL （%） 99.9 Cumulative failure rate Load conditions Voltage: 5VDC Current: 100µA , 1mA , 5mA Load: Resistive load 90 70 50 30 10 5 1 No failure 5mA 1mA 100mA 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. （%） 99.9 Cumulative failure rate Load conditions Voltage: 12VDC Current: 5mA , 10mA , 100mA Load: Resistive load 90 70 50 30 10 5 1 No failure 100mA 10mA 5mA 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. （%） 99.9 Load conditions Voltage: 24VDC Current: 100mA , 200mA , 400mA Load: Resistive load Cumulative failure rate 90 70 50 30 10 5 1 400mA 200mA 100mA 0.1 0 23 5 7 105 23 5 7 106 23 5 7 107 23 5 7 108 Number of operations 78
