RI-70 Series Dry Reed Switch RI-70 Series Ultra-miniature 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-70 Series Features ▪ Ideal for ATE switching ▪ 7 mm glass length ▪ Contact layers: gold, sputtered ruthenium ▪ Superior glass-to-metal seal and blade alignment ▪ Excellent life expectancy and reliability ▪ RoHS Compliant All Dimension in inches (mm) nominal General data for all models RI-70 AT-Customization / Performed Leads Besides the standard models, customized products can also be supplied offering the following options: • Operate and release ranges to customer specification • Cropped and/or performed leads Coils All characteristics are measured using the Philips Standard Coil. For definitions of the Philips Standard Coil, refer to “Application Notes” in the Reed Switch Technical & Application Information Section of this catalog. Life expectancy and reliability 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-70 series. No load conditions (operating frequency: 100Hz) Life expectancy: min. 109 operations with a failure rate of less than 2 x 10-10 with a confidence level of 90%. End of life criteria: Contact resistance > 1Ω after 2 ms Release time > 2 ms (latching or contact sticking). Loaded conditions (resistive load: 5 V; 100 mA; operating frequency: 125 Hz) Life expectancy: min. 2 x 107 operations with a failure rate of less than 10-8 with a confidence level of 90%. End of life criteria: Contact resistance > 1Ω after 2.5 ms Release time > 1 ms (latching or contact sticking). Loaded conditions (resistive load: 20 V; 500 mA; operating frequency: 125 Hz) Life expectancy: min. 5 x 106 operations with a failure rate of less than 0.5 x 10-7 with a confidence level of 90%. End of life criteria: Contact resistance > 2Ω after 2.5 ms Release time > 2.5 ms (latching or contact sticking). Switching different loads involves different life expectancy and reliability data. Further information is available on request. Mechanical Data Contact arrangement is normally open; lead finish is

tinned; net mass is approximately 70mg; and can be mounted in any position. The switches are tested in accordance with “IEC 68-2-27”, test Ea (peak acceleration 100 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 close. The switches are tested in accordance with “IEC 68-2-26”, test Fc (acceleration 10G; 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...
