Features
Small size
SMT-compatible
Easily formed leads
Sputtered ruthenium contacts
Hermetically sealed contacts
Fast switching speed — up to 500Hz
Wide range of available magnetic sensitivities
Description
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.

Ordering Information
A complete part number is represented by the digits to the right. For example, FR2S1030 is a
DYAD® with a minimum operate value of 10 and a maximum of 30. Refer to the switch operating
specification charts for available ranges. Special ranges are available upon request.

Absolute Maximum Ratings are stress ratings. Stresses
in excess of these ratings can cause permanent damage
to the device. Functional operation of the device at these
or any other conditions beyond those indicated in the
operational sections of this data sheet is not implied.
Exposure of the device to the absolute maximum ratings
for extended period may degrade the device and effect
its reliability.
