formerly RI-26 Series Dry Reed Switch RI-26 Series Close differential micro 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 applications with small hysteresis in switching behavior. Dimensions for RI-26 Series RI-26 Series Features Close differential reed switch Contact layers: gold, plated ruthenium Superior glass-to-metal seal and blade alignment Excellent life expectancy and reliability RoHS Compliant 0.906 0.020 (23.0 0.5) tinned 0.100 max (O2.54) 0.024 max (O0.60) 0.570 max (14.5) 1.811 0.020 (46.0 0.5) All Dimension in inches (mm) nominal General data for all models RI-26 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 1.5 times the published maximum operate value for each type in the RI-26 series. No load conditions (operating frequency: 100Hz) Life expectancy: min. 3 x 108 operations with a failure rate of less than 0.9 x 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: 20 V; 500 mA; operating frequency: 125 Hz) Life expectancy: min. 5 x 107 operations with a failure rate of less than 5 x 10-9 with a confidence level of 90%. End of life criteria: Contact resistance > 2 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 190mg; and can be mounted in any position. Shock The switches are tested in accordance with "IEC 68-2-27", test Ea (peak acceleration 50 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 USA Tel: +(1)973 777 6900 / Fax: +(1) 973 777 8405 Belgium Tel: + 32 (0)12 390400 Page 1 of 3 RI-26 Series Dry Reed Switch Technical Specifications Parameters Test Conditions Units RI-26AA RI-26A RI-26B AT 14-23 18-32 28-52 % 80 75 70 Operate Time - including Bounce (typ.) ms 0.30 0.30 0.30 Bounce Time (typ.) ms 0.15 0.15 0.15 Release Time (max) s 30 30 30 Resonant Frequency (typ.)

The leads can be welded. Vibration The switches are tested in accordance with "IEC 68-2-6", test Fc (acceleration 10G; below cross-over-frequency 58 Hz; amplitude 0.75 mm; frequency range 10 to 2000 Hz; duration 75 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. Mounting 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 40 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.

Soldering The switch can withstand soldering heat in accordance with "IEC 68-2-20", test Tb, method 1B: solder bath at 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. * As part of the company policy of continued product improvement, specifications may change without notice.Our sales office will be pleased to help you with the latest information on this product range and the details of our full design and manufacturing service.
