RI-80 Series Dry Reed Switch
RI-80 Series
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.
