Single-pole reed switch RI-03 series

micro

Micro dry-reed switch hermetically sealed in a gas-filled 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 sensors, relays, pulse counters or similar devices. Features ▪ Ideal for general purpose reed relays and sensors. ▪ Contact layers: ruthenium on gold ▪ Superior glass-to-metal seal and blade alignment ▪ RoHS Compliant 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 1.25 times the published maximum operate value for each type in the RI-03 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: End of life criteria: Contact resistance > 1Ω after 2 ms Release time > 2 ms (latching or contact sticking). Mechanical Data Contact arrangement is normally open; lead finish is tinned; net mass is approximately 190mg; and can be mounted in any position.
