RI-05 Series Dry Reed Switch RI-05 Series Close differential 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 sensors, relays, pulse counters or similar devices. RI-05 Series Features ▪ Close differential reed switch ▪ Contact layers: ruthenium on gold ▪ Superior glass-to-metal seal and blade alignment ▪ RoHS Compliant Dimensions for RI-05 Series 0.906 ± 0.020 (23.0 ± 0.5) tinned All Dimension in inches (mm) nominal General data for all models RI-05 AT-Customization / Preformed 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 preformed 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-05 series. No load conditions (operating frequency: 100Hz) Life expectancy: min. 2 x 10 operations with a failure rate of less than 10-9 with a confidence level of 90%. End of life criteria: Contact resistance > 1Ω after 2 ms Release time > 2 ms (latching or contact sticking). 8 Loaded conditions (resistive load: 12 V; 4 mA; (15 mA peak); operating frequency: 170 Hz) Life expectancy: min. 106 operations. End of life criteria: Contact resistance > 2Ω 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. 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.

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. • As part of the company policy of continued product improvement, specifications may change without notice.
