RI-25 Series Dry Reed Switch RI-25 Series 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 high load applications in relays or switching devices. RI-25 Series Features ▪ Can handle up to 25 W load ▪ Contact layers: gold, plated 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-25 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-25 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 > 1Ω after 2 ms Release time > 2 ms (latching or contact sticking). Loaded conditions (resistive load: 20 V; 500 mA; operating frequency: 125 Hz) RI-25AAA Life expectancy: min. 106 operations with a failure rate of less than 2.5 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) RI-25AA; RI-25A; RI-25B; RI-25C 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 > 2Ω after 2.5 ms Release time > 2.5 ms (latching or contact sticking) Loaded conditions (resistive load: 50 V; 100mA; operating frequency: 50 Hz) Life expectancy: min. 106 operations with a failure rate of less than 2 x 10-7 with a confidence level of 90%. End of life criteria: Contact resistance >1Ω after 5 ms Release time > 2 ms (latching or contact sticking)

* The Contact Resistance is measured using the Kelvin Method next to the glass body. Switching different loads involves different life expectancy and reliability data. Further information is available on request. Contact arrangement is normally open; lead finish is tinned; net mass is approximately 190mg; and can be mounted in any position. 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 closedby an 80 AT coil to open. The...
