RI-27 SMD Series

Pico dry-reed switch hermetically sealed in a gas-filled glass envelope. Single-

pole, single-throw (SPST) type, having normally open contacts, and contain-

ing 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-27 SMD Series Features

▪ Ideal for ATE switching

▪ Contact layers: gold, sputtered ruthenium

▪ Superior glass-to-metal seal and blade alignment

▪ Excellent life expectancy and reliability

▪ RoHS Compliant
