Description
Clare鈥檚 DYAD
廬
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.
