Features

Description

• Small size

Clare’s DYAD^®dry reed switches are ideally suited for

small switching signal applications. This switch has

sputtered ruthenium contacts and an extraordinary seal

strength, achieved by a patented laser sealing of the glass.

In low level or dry switching environments, both switches

typically provide >1 billion operations. The switches have

hermetically sealed contacts and offer a wide range of

available magnetic sensitivities.

• SMT-compatible

• Easily formed leads

• Sputtered ruthenium contacts

• Hermetically sealed contacts

• Fast switching speed — up to 500Hz

• Wide range of available magnetic sensitivities

Applications

• Security

• Proximity sensing

• Smoke alarms

• Automotive

Standard Test Coil

The magnetic force (expressed in NI, AT or Ampere Turns) required to cause the reed switch contacts to

close is called the pull-in or operate value.
