RI-02 SMD Series Dry Reed Switch
RI-02 SMD Series
Ultra-miniature dry-reed switch hermetically sealed in a gas lled envelope.
Single-pole, single-throw (SPST) type, having normally open contacts, and
containing two magnetically actuated reeds.
e switch is of the double-ended type and may be actuated by an electro-
magnet, a permanent magnet or combination of both. e device is intended
for use in senors, relays, pulse counters or similar devices.
RI-02 SMD Series Features
▪ Ideal for general purpose reed relays and sensors.
▪ Contact layers: ruthenium on gold
▪ Superior glass-to-metal seal and blade alignment
▪ RoHS Compliant
