RI-80 SMDH Series Housed Dry Reed Switch
RI-80 SMDH Series
Ultra-micro dry-reed switch hermetically sealed in a gas-lled glass 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 a combination of both.
RI-80 SMDH Series Features
▪ Ideal for proximity sensors, telecom & medical applications
▪ Contact layers: gold, sputtered ruthenium
▪ Superior glass-to-metal seal and blade alignment
▪ RoHS Compliant
