Description
Clare’s Molded 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. In addition, the molding
process provides a solid plastic outer shell. This plastic
shell provides superior mechanical strength, eliminates
concerns over handling glass switches, and provides an
ideal solution for high speed, automated assembly
environments."

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.
