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.
