RI-60 Series Dry Reed Switch RI-60 Series Ultra-miniature 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 relays, sensors, pulse counters or similar devices. RI-60 Series Features Ideal for ATE switching Contact layers: Gold, sputtered ruthenium Superior glass-to-metal seal and blade alignment Excellent life expectancy and reliability Dimensions in inches (mm) General data for all models RI-60 Loaded conditions (resistive load: 5 V 100 mA operating frequency: 125 Hz) 7 AT-Customization / Preformed Leads Life expectancy: min. 2 x 10 operations with a failure -8 Besides the standard models, customized products rate of less than 10 with a confidence level of 90%. can also be supplied offering the following options: End of life criteria: Operate and release ranges to customer specification Contact resistance > 1 after 2.5 ms Cropped and/or preformed leads Release time > 1 ms (latching or contact sticking).
