J2R0024-41-31 REED SWITCH ORT551 Ultraminiature Transfer n GENERAL DESCRIPTION The OR551 is a ultraminiature two-contacts reed switch designed for transfer type operation. 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 f2.54 f0.5 N.C f0.5 N.O MAX 14.0 51.6±0.3 56.1±0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances 127 l ORT551 n ELECTRICAL CHARACTERISTICS Parameter Rated value Unit 10∼30 AT Pull-in Value (PI) Drop-out Value (DO) Contact resistance (CR) Breakdown voltage 4min AT 100max mW 200min (PI≧20) VDC 150min (PI＜20) VDC Insulation resistance 109min W Electrostatic capacitance 1.5max pF 3 VA Maximum switching voltage DC 30（ ） AC V Maximum switching current 0.2 A Maximum carry current 0.5 A Contact rating (1) Drop-out Value vs. Pull-in Value (2) Contact resistance (Measurement length: 30mm) 99.9 Cumulative frequency percent (%) Drop-out Value AT 50 40 30 20 10 0 N.O N.C 95 90 80 70 60 50 40 30 20 10 5 1 0.1 10 20 30 Pull-in Value 128 99 40 50 AT 40 60 80 Contact resistance 100 mW ORT551 l (3) Breakdown voltage (4) Insulation resistance （DC 100V） 99.9 Cumulative frequency percent 99 Breakdown voltage DC：V 400 300 200 100 0 95 90 80 70 60 50 40 30 20 10 5 1 10 20 30 40 50 AT Pull-in Value 0.1 10 9 1010 10 11 1012 1013 W Insulation resistance (5) Electrostatic capacitance （1MHz） Electrostatic capacitance pF 1.5 1.0 0.5 0 10 20 30 40 50 AT Pull-in Value 129 l ORT551 n OPERATING CHARACTERISTICS Rated value Unit Operate time 1.0max ms Bounce time NO 1.0max ms Parameter NC 1.5max ms 0.5max ms 6000±4000 Hz 200 Hz Release time Resonant frequency Maximum operating frequency (1) Operate time (2) Bounce time (25Hz: 100AT energized) 99 Cumulative frequency percent 0.5 0.4 Operate time (25Hz: 100AT energized) 99.9 ms 0.3 0.2 0.1 N.O N.C 95 90 80 70 60 50 40 30 20 10 5 1 0 0.1 10 20 30 40 50 0 AT 0.5 1.0 1.5 ms Bounce time Pull-in Value (3) Release time (4) Resonant frequency 99.9 (25Hz: 100AT energized) Release time ms 30 20 10 0 95 90 80 70 60 50 40 30 20 10 5 1 0.1 5 10 15 20 Drop-out Value 130 Cumulative frequency percent 99 25 AT 2000 6000 10000 Resonant frequency Hz ORT551 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) (2) Lead tensile strength （2.27kg-10sec） 99.9 Cumulative frequency percent (%) Pull-in Value ･ Drop-out Value AT 60 50 40 30 20 PI DO 10 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 2 4 Contact resistance 6 8 10kg Breaking load 0 mW 80 60 CR CR 40 N.O N .C Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 CR Rate of change percent 30 20 PI 10 DO 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 131 l ORT551 (2) Temperature cycle (3) Temperature and humidity cycle -10℃∼+65℃ 80％∼98％ (-55℃∼+125℃) AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI DO 10 50 40 30 20 Contact resistance 0 mW 80 Contact resistance 0 CR CR 40 60 CR CR 40 N.O N .C Before test DO 10 mW 80 60 PI N.O N .C After test Before test (4) High temperature storage test (5) Low temperature storage test (-40℃-500H) (+125℃-500H) AT 60 50 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value AT 60 40 30 20 PI DO 10 50 40 30 20 Contact resistance mW 80 Contact resistance 0 mW 80 60 PI 10 0 CR CR 40 N.O N .C Before test 132 After test DO 60 CR CR 40 N.O N .C After test Before test After test ORT551 l (6) Shock test 1) Electrical characteristics 2) Misoperation area (open→close) (30G: 11ms) AT 60 G 50 40 30 20 Acceleration Pull-in Value • Drop-out Value 1500 PI 10 1000 DO 500 Misoperation area Contact resistance 0 mW 80 60 0 CR CR 10 20 30 40 50 60 AT Pull-in Value 40 N.O N .C Before test After test (7) Vibration test (20G: 10∼1000Hz) Pull-in Value • Drop-out Value AT 60 50 40 30 20 PI DO 10 Contact resistance 0 mW 80 60 CR CR 40 N.O N .C Before test After test 133 l ORT551 n LIFE EXPECTANCY DATA: ORT551 Load conditions Voltage: 5VDC Current: 100mA, 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 5 7 107 2 3 5 7 108 Number of operations * Arrow indicates number of operations where test was completed.
