RI-08 Series Dry Reed Switch
RI-08 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
electromagnet, a permanent magnet or a combination of both.
The device is intended for use in sensors, relays, pulse counters or similar
devices.
