RI-07 Series RI-07 SERIES Pico dry-reed switch hermetically sealed in a gas-filled glass envelope. Single-pole, single-throw (SPST) type, having normally open contacts, and containing two magnetically actuated reeds. The switch is of the double-ended type and may be actuated by an electromagnet, a permanent magnet or a combination of both. The device is intended for use in relays, sensors, pulse counters or similar devices. RI-07 SERIES FEATURES u Ideal for general purpose reed relays and sensors u Contact layers: Gold/copper, sputtered or plated ruthenium(can vary) u Superior glass-to-metal seal and blade alignment Dimensions in inches (mm) GENERAL DATA FOR ALL MODELS RI-07 AT-Customization / Pr ef ormed Leads Pref eformed Besides the standard models, customized products can also be supplied offering the following options: ! Operate and release ranges to customer specification ! Cropped and/or preformed leads C OILS All characteristics are measured using the Philips Standard Coil. For definitions of the Philips Standard Coil and the standard MIL Coil, refer to "Application Notes" in the Reed Switch Technical & Application Information Section of this catalog. Relationship betw een Philips Standar d Coil and the between Standard Standar d MIL Coil Standard Operate value of standard MIL Coil = 0.78 x operate value of Philips Standard Coil + 1.02 AT. Release value of standard MIL Coil = 0.83 x release value of Philips Standard Coil + 0.01 AT. L IFE EXPECT ANCY AND RELIABILITY EXPECTANCY The life expectancy data given below are valid for a coil energized at 1.25 times the published maximum operate value for each type in the RI-07 series. End of life criteria: Contact resistance > 1 after 2 ms Release time > 2ms (latching or contact sticking). Loaded conditions (resistive load: 5V; 100 mA; operating f rrequency: equency: 125 Hz) Life expectancy: min. 107 operations with a failure rate of less than 10-8 with a confidence level of 90%. End of life criteria: Contact resistance > 1 after 2.5 ms Release time > 1 ms (latching or contact sticking). Loaded conditions (resistive load: 12V; 4 mA; (15 mA peak); operating frequency: 170 Hz) Life expectancy: min. 106 operations End of life criteria: Contact resistance > 2 after 4 ms Release time > 0.7 ms (latching or contact sticking). Switching different loads involves different life expectancy and reliability data. Further information is available on request. No-load conditions (operating frequency: 100 Hz) Life expectancy: min. 108 operations with a failure rate of less than 10-9 with a confidence level of 90%.

MECHANICAL DATA Contact arrangement is normally open; lead finish is tinned; net mass is approximately 0.10 g; and can be mounted in any position. SHOCK The switches are tested in accordance with "IEC 68-2-27", test Ea (peak acceleration 150 G, half sinewave; duration 11 ms). Such a shock will not cause an open switch (no magnetic field present) to close, nor a switch kept closed by an 80 AT coil to open. VIBRA TION IBRATION The switches are tested in accordance with "IEC 68-2-6", test Fc (acceleration 10 G; below cross-over frequency 57 to 62 Hz; amplitude 0.75 mm; frequency range 10 to 2000 Hz, duration 90 minutes). Such a vibration will not cause an open switch (no magnetic field present) to close, nor a switch kept closed by an 80 AT coil to open. MECHANICAL STRENGTH The robustness of the terminations is tested in accordance with "IEC 68-2-21", test Ua1 (load 10 N). 6 10 6 10 6 OPERA TING AND STORA GE TEMPERA TURE PERATING ORAGE EMPERATURE Operating ambient temperature; min: -55C; max: +125C. Storage temperature; min: -55C; max: +125C. Note: Temperature excursions up to 150C may be permissible. For more information contact your nearest Coto Technology sales office. SOLDERING The switch can withstand soldering heat in accordance with "IEC 68-2-20", test Tb, method 1B: solder bath at 350 10 C for 3.5 0.5 s. Solderability is tested in accordance with "IEC 68-2-20" test Ta, method 3: solder globule temperature 235C; ageing 1b: 4 hours steam. W ELDING The leads can be welded M OUNTING The leads should not be bent closer than 1 mm to the glass-tometal seals. Stress on the seals should be avoided. Care must be taken to prevent stray magnetic fields from influencing the operating and measuring conditions.
