Coto 9853 Reed Relay

Core Performance & Industrial Application

The Coto Technology 9853 is a CotoClassic Form C (SPDT) surface-mount reed relay designed for ATE, instrumentation and telecommunications.

Real break-before-make switching routes an incoming signal to either the NO or NC contact on coil actuation.

The 50 Ω coaxial shield and gold-plated terminals support high-frequency signal routing; external magnetic shield suppresses crosstalk.

Hermetically sealed contacts deliver long life at signal level: 100×10⁶ N/C, 200×10⁶ N/O operations at 1 V / 10 mA.

High-speed operate/release time around 1 ms suits scanner and multiplexer switching.
