formerly RI-07 Series Dry Reed Switch RI-07 Series Pico dry-reed switch hermetically sealed in a gas-filled glass envelope. Singlepole, 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 Ideal general purpose reed relays and sensors Contact layers: ruthenium on gold Superior glass-to-metal seal and blade alignment RoHS Compliant Dimensions for RI-07 Series 0.906 0.020 (23.0 0.5) tinned 0.071 max (O1.8) 0.020 max (O0.50) 0.531 max (13.5) 1.811 0.020 (46.0 0.5) All Dimension in inches (mm) nominal General data for all models RI-07 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-07 series. No load conditions (operating frequency: 100Hz) Life expectancy: min. 108 operations with a failure rate of less than 10-9 with a confidence level of 90%. End of life criteria: Contact resistance > 1 after 2 ms Release time > 2 ms (latching or contact sticking). Loaded conditions (resistive load: 5V; 100 mA; operating frequency: 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. Mechanical Data Contact arrangement is normally open; lead finish is tinned; net mass is approximately 100mg; and can be mounted in any position.

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. 350 10C 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. Welding The leads can be welded. Mounting Vibration The switches are tested in accordance with "IEC 68-2-6", 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 kept closed by an 80 AT coil to open. The leads should not be bent closer than 1 mm to the glass-to-metal seals. Stress on the seals should be avoided Care must be taken to prevent stray magnetic fields from influencing the operating and measuring conditions. Mechanical Strength The robustness of the terminations is tested in accordance with "IEC 68-2-21", test Ua1 (load 10 N). Operating and Storage Temperature Operating ambient temperature; min: -55C; max: +125C. Storage temperature; min: -55; max: +125C. Note: Temperature excursions up to 150C may be permissible.
