ORT551

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 N.C f0.5 N.O MAX 14.0 51.6±0.3 56.1±0.3 MAX f2.54 f0.5 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 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∼30 4min 100max 200min (PI≧20) 150min (PI＜20) 109min 1.5max 3 DC 30（ ） AC Unit AT AT mW VDC VDC W pF VA V A A 0.2 0.5 (1) Drop-out Value vs. Pull-in Value (2) Contact resistance 99.9 (Measurement length: 30mm) N.O N.C Cumulative frequency percent (%) 10 20 30 Pull-in Value 40 50 AT 50 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 40 Drop-out Value 40 30 20 10 0 AT 60 80 100 mW Contact resistance 128 ORT551 l (3) Breakdown voltage (4) Insulation resistance 99.9 99 （DC 100V） Cumulative frequency percent DC：V 400 Breakdown voltage 95 90 80 70 60 50 40 30 20 10 5 1 300 200 100 0 10 20 30 Pull-in Value 40 50 AT 0.1 10 9 1010 10 11 1012 1013 W Insulation resistance (5) Electrostatic capacitance （1MHz） pF Electrostatic capacitance 1.5 1.0 0.5 0 10 20 30 Pull-in Value 40 50 AT 129 l ORT551 n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 1.0max NO 1.0max NC 1.5max 0.5max 6000±4000 200 Unit ms ms ms ms Hz Hz (1) Operate time (25Hz: 100AT energized) ms 0.5 Cumulative frequency percent (2) Bounce time (25Hz: 100AT energized) N.O N.C 99.9 99 95 90 80 70 60 50 40 30 20 10 5 1 0.4 Operate time 0.3 0.2 0.1 0 0.1 10 20 30 Pull-in Value 40 50 AT 0 0.5 1.0 Bounce time 1.5 ms (3) Release time (4) Resonant frequency 99.9 99 Cumulative frequency percent (25Hz: 100AT energized) ms 30 Release time 95 90 80 70 60 50 40 30 20 10 5 1 0.1 20 10 0 5 10 15 20 25 AT 2000 6000 10000 Hz Drop-out Value Resonant frequency 130 ORT551 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) （2.27kg-10sec） AT 60 (2) Lead tensile strength 99.9 Cumulative frequency percent (%) DO 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 2 4 6 8 10kg Pull-in Value ･ Drop-out Value 50 40 30 20 PI 10 0 Contact resistance mW 80 Breaking load 60 CR 40 CR N.O N .C Before test After test n ENVIRONMENTAL CHARACTERISTICS (1) Temperature characteristics ％ 40 CR 30 Rate of change percent 20 PI 10 DO 0 −10 −20 −30 −40 −20 0 20 40 60 80 100 120 ℃ Temperature 131 l ORT551 (2) Temperature cycle (-55℃∼+125℃) AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value (3) Temperature and humidity cycle -10℃∼+65℃ 80％∼98％ AT 60 50 50 40 40 30 30 20 PI DO 20 PI DO 10 10 0 Contact resistance Contact resistance mW 80 0 mW 80 60 CR 40 CR 60 CR 40 CR N.O N .C Before test After test N.O N .C Before test After test (4) High temperature storage test (+125℃-500H) (5) Low temperature storage test (-40℃-500H) AT 60 AT 60 Pull-in Value • Drop-out Value Pull-in Value • Drop-out Value 50 50 40 40 30 30 20 PI DO 20 PI 10 10 DO 0 mW 80 0 Contact resistance mW 80 Contact resistance 60 CR 40 CR 60 CR 40 CR N.O N .C Before test After test N.O N .C Before test After test 132 ORT551 l (6) Shock test 1) Electrical characteristics (30G: 11ms) AT 60 Pull-in Value • Drop-out Value 2) Misoperation area (open→close) G 1500 50 40 30 Acceleration DO 1000 20 PI 10 500 0 Contact resistance mW 80 Misoperation area 60 CR CR 40 N.O N .C Before test After test 0 10 20 30 40 50 60 AT Pull-in Value (7) Vibration test (20G: 10∼1000Hz) AT 60 Pull-in Value • Drop-out Value 50 40 30 PI 20 10 DO 0 Contact resistance mW 80 60 CR 40 CR N.O N .C Before test After test 133 l ORT551 n LIFE EXPECTANCY DATA: ORT551 （%） 99.9 90 70 50 30 10 5 No failure 5mA , 1mA , 100mA Load conditions Voltage: 5VDC Current: 100mA, 1mA, 5mA Load: Resistive load Cumulative failure rate 1 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 100mA 10mA 5mA 1 0.1 0 23 5 7 105 23 5 7 106 23 5 7 107 23 5 7 108 Number of operations （%） 99.9 Voltage: 24VDC Current: 50mA, 100mA Load: Resistive load Cumulative failure rate Load conditions 90 70 50 30 10 5 100mA 50mA 1 0.1 0 23 5 7 105 23 5 7 106 23 5 7 107 23 5 7 108 Number of operations 134
