| REED SWITCH ORD2220 Miniature Wide Differential n GENERAL DESCRIPTION The ORD2220 is a small single-contact reed switch designed for general control of low-level loads less than 40 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 56.7 0.3 n APPLICATIONS l Automotive electronic devices l Control equipment l Communication equipment l Measurement equipment l Household appliances l ORD2220 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 08 40 3min 100max 200min 109min 0.3max 16 40 DC AC Unit AT AT mW VDC W pF VA V A A 0.4 0.7 (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 Drop-out Value 40 30 20 10 0 10 20 30 Pull-in Value 40 50 AT Contact resistance ORD2220 l (3) Breakdown voltage (4) Insulation resistance 99.9 99 Cumulative frequency percent DC 100V 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 10 10 11 10 12 10 13 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 l n OPERATING CHARACTERISTICS Parameter Operate time Bounce time Release time Resonant frequency Maximum operating frequency Rated value 0.4max 0.3max 0.05max 4400 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 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 4000 4500 5000 Hz Drop-out Value Resonant frequency ORD2220 l n MECHANICAL CHARACTERISTICS (1) Lead tensile test (static load) 2.27kg-10sec AT 60 Cumulative frequency percent (%) 99.9 99 95 90 80 70 60 50 40 30 20 10 5 1 0.1 0 2 4 6 8 10kg Breaking load (2) Lead tensile strength Pull-in Value * Drop-out Value 50 40 30 PI 20 DO 10 0 Contact resistance mW 80 CR 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 l ORD2220 (2) Temperature cycle (-55 AT 60 Pull-in Value * Drop-out Value Pull-in Value * Drop-out Value (3) Temperature and humidity cycle +125 ) AT 60 -10 80 +65 98 50 50 40 40 30 PI 20 DO 30 PI 20 DO 10 10 0 Contact resistance Contact resistance mW 80 CR 0 mW 80 CR 60 60 40 Before test After test 40 Before test After test (4) High temperature storage test (+125 -500H) AT 60 Pull-in Value * Drop-out Value Pull-in Value * Drop-out Value (5) Low temperature storage test -500H) AT 60 50 50 40 40 30 PI 20 DO 30 PI 20 DO 10 10 0 Contact resistance Contact resistance mW 80 CR 0 mW 80 CR 60 60 40 Before test After test 40 Before test After test ORD2220 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 PI 20 DO Acceleration 30 1000 Misoperation area 10 500 0 Contact resistance mW 80 CR 60 0 10 20 30 40 50 60 AT Pull-in Value 40 Before test After test (7) (20G: 10 1000Hz) AT 60 Pull-in Value * Drop-out Value 50 40 30 PI 20 DO 10 0 Contact resistance mW 80 CR 60 40 Before test After test l ORD2220 n LIFE EXPECTANCY DATA: ORD2220 % 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 90 70 50 30 10 5 No failure 100mA 10mA 5mA Current: 5mA, 10mA, 100mA Load: Resistive load Cumulative failure rate Load conditions Voltage: 12VDC 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 90 70 50 30 10 5 400mA 200mA 100mA Voltage: 24VDC Current: 100mA, 200mA, 400mA Load: Resistive load Cumulative failure rate Load conditions 1 0.1 0 23 5 7 105 23 5 7 106 23 5 7 107 23 5 7 108 Number of operations |
