J2R0015-41-31 l OR D228VL 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 MAX f2.2 14.0 44.30.3 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 Rated value Unit 1050 AT Pull-in Value (PI) Drop-out Value (DO) Contact resistance (CR) Breakdown voltage 5min AT 100max mW 200 min (PI20) VDC 150 min (PI20) VDC Insulation resistance 109min W Electrostatic capacitance 0.3max pF 10 VA Maximum switching voltage 100 DC AC V Maximum switching current 0.5 A Maximum carry current 1.0 A Contact rating (1) Drop-out Value vs. Pull-in Value (2) Contact resistance (Measurement length: 32mm) 99.9 Cumulative frequency percent (%) AT 50 Drop-out Value 40 30 20 10 0 10 20 30 Pull-in Value 72 40 50 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 AT 40 60 80 Contact resistance 100 mW ORD228VL l (3) Breakdown voltage (4) Insulation resistance DC 100V Cumulative frequency percent (%) 99.9 Breakdown voltage DCV 400 300 200 100 0 10 20 30 40 50 Pull-in Value AT 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 10 11 10 12 10 13 10 10 14 W Insulation resistance (5) Electrostatic capacitance 1MHz pF Electrostatic capacitance 0.4 0.3 0.2 0.1 0 10 20 30 40 50 AT Pull-in Value 73 l ORD228VL n OPERATING CHARACTERISTICS Rated value Unit Operate time Parameter 0.4max ms Bounce time 0.3max ms Release time 0.05max ms 5000400 Hz 500 Hz Resonant frequency Maximum operating frequency (1) Operate time (2) Bounce time (25Hz: 100AT energized) (25Hz: 100AT energized) 99.9 Cumulative frequency percent (%) ms 0.5 Operate time 0.4 0.3 0.2 0.1 0 10 20 30 40 50 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 AT 0.1 Pull-in Value 0.2 0.3 0.4 ms Bounce time (3) Release time (4) Resonant frequency Release time (25Hz: 100AT energized) ms 15 10 5 0 10 20 30 40 Drop-out Value 74 50 Cumulative frequency percent (%) 99.9 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 AT 4500 5000 5500 Resonant frequency Hz ORD228VL l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (2) Lead tensile strength 2.27kg-10sec 99.9 50 40 30 99 Cumulative frequency percent (%) Pull-in Value * Drop-out Value AT 60 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 40 CR Rate of change percent 30 20 DO 10 PI 0 -10 -20 -30 -40 -20 0 20 40 60 80 100 120 Temperature 75 l ORD228VL (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 20 DO 0 0 mW 80 mW 80 60 PI 10 Contact resistance Contact resistance 10 50 CR 40 Before test 60 CR 40 Before test After 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 30 PI 20 DO 0 0 mW 80 mW 80 Contact resistance Contact resistance 40 10 10 CR 40 Before test 76 50 DO 60 After test After test 60 CR 40 Before test After test ORD228VL l (6) Shock test 1) Electrical characteristics 2) Misoperation area (openclose) (30G: 11ms) G 1500 50 40 30 Acceleration Pull-in Value * Drop-out Value AT 60 PI 20 DO 1000 Misoperation area 10 500 Contact resistance 0 mW 80 60 CR 0 10 20 30 40 50 60 AT Pull-in Value 40 Before test After test (7) Vibration test (20G: 101000Hz) Pull-in Value * Drop-out Value AT 60 50 40 30 PI 20 DO 10 Contact resistance 0 mW 80 60 CR 40 Before test After test 77 l ORD228VL n LIFE EXPECTANCY DATA: ORD228VL Load conditions Voltage: 5VDC Current: 100A , 1mA , 5mA Load: Resistive load Cumulative failure rate % 99.9 90 70 50 30 No failure 5mA 1mA 100mA 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.
