formerly RI-46 Series Dry Reed Switch RI-46 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 elec - tromagnet, a permanent magnet or a combination of both. The device is intended for use in relays, sensors, pulse counters or similar devices. RI-46 Series Features Can switch main voltage Can handle up to 40 W load Contact layers: gold, sputtered ruthenium Superior glass-to-metal seal and blade alignment Excellent life expectancy and reliability RoHS Compliant Dimensions for RI-46 Series 1.079 0.020 (27.4 0.5) tinned 0.106 max 0.026 max (2.7) (0.65) 0.807 max (20.5) 2.157 0.020 (54.8 0.5) All Dimension in inches (mm) nominal General data for all models RI-46 AT-Customization / Performed Leads Release time > 2 ms (latching or contact sticking).
