| J2R0019-41-31 l REED SWITCH ORD229 High Breakdown Voltage n GENERAL DESCRIPTION The ORD229 is a single-contact reed switch designed for high breakdown voltage of 600 VDC and high power of AC 70 VA and DC 50 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 an operating system and electrical circuits coaxially. Reed switches are suited to applications in radio frequency. (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) f f n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances l ORD229 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 Unit 20 60 6min 100 600 min (PI 35) 500 min (PI 20 to 35) 1010min 0.5max 50 70 300AC 350DC DC0.7/AC0.5 2.5 W W (1) Drop-out Value vs. Pull-in Value (2) Contact resistance (Measurement length: 32mm) Cumulative frequency percent (%) Drop-out Value W Pull-in Value Contact resistance ORD229 l (3) Breakdown voltage (4) Insulation resistance Cumulative frequency percent (%) Breakdown voltage W Pull-in Value Insulation resistance (5) Electrostatic capacitance (1MHz) Electrostatic capacitance Pull-in Value l ORD229 n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value Unit (1) Operate time (25Hz: 100AT energized) (2) Bounce time (25Hz: 100AT energized) Pull-in Value Cumulative frequency percent (%) Operate time Bounce time (3) Release time (4) Resonant frequency (25Hz: 100AT energized) (25Hz: 100AT energized) m Release time Drop-out Value Cumulative frequency percent (%) Resonant frequency ORD229 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (2) Lead tensile strength Cumulative frequency percent (%) Pull-in Value * Drop-out Value Breaking load Contact resistance W Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics Rate of change percent Temperature l ORD229 (2) Temperature cycle (-55 to 125 ) (3) Temperature and humidity cycle -10 to 65 80% to 98% Pull-in Value * Drop-out Value W Pull-in Value * Drop-out Value W Contact resistance Before test After test Contact resistance Before test After test (4) High temperature storage test (+125 -500H) (5) Low temperature storage test -500H) Pull-in Value * Drop-out Value Pull-in Value * Drop-out Value Contact resistance W W Contact resistance Before test After test Before test After test ORD229 l (6) Shock test 1) Electrical characteristics (30G: 11ms) 2) Misoperation area (open close) Pull-in Value * Drop-out Value Acceleration Misoperation area W Contact resistance Pull-in Value Before test After test (7) Vibration test (20G: 10 1000Hz) Pull-in Value * Drop-out Value W Contact resistance Before test After test l ORD229 n % Load conditions Voltage: Current: Load: Resistive load Cumulative failure rate No failure 0 23 5 7 105 23 57 106 23 57 107 23 57 108 Number of operations * Arrow indicates number of operations where test was completed. % Load conditions Voltage: 350VDC, 270VDC Current: 1mA, 270A Load: Resistive load Cumulative failure rate No failure m 0 23 5 7 105 23 57 106 23 57 107 23 57 108 Number of operations * Arrow indicates number of operations where test was completed. % Cumulative failure rate Load conditions Voltage: 100VDC, 50VDC Current: 0.5A, 1.0A, 0.5A Load: Resistive load No failure 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. |
