Single-pole reed switch RI-80

subminiaturemicroproximity

Ultra-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 sensors, relays, pulse counters or similar devices. Features ▪ Ideal for ATE switching, proximity sensors & medical applications ▪ Contact layers: gold, sputtered ruthenium ▪ Superior glass-to-metal seal and blade alignment ▪ RoHS Compliant 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-80 series. No load conditions (operating frequency: 100Hz) Life expectancy: min. 108 operations with a failure rate of less than 2 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: 5V; 100 mA; operating frequency: 170 Hz) 107 operations with a failure rate of less than 10-8 with a confidence level of 90%.
