RI-01C Datasheet, PDF (1/2 Pages) Coto Technology – Dry Reed Switch

RI-01C Series Dry Reed Switch
RI-01C Series
Pico dry-reed switch hermetically sealed in a gas-filled glass envelope.
Single-pole, single-throw (SPST) type, having normally open con-
tacts, 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.
