Description
Clare's Molded Mini DYAD dry reed switches are ideally
suited for small switching signal applications. This switch
has sputtered tuthenium contacts and an extraordinary
seal strength, achieved by a patented laser sealing of the
glass. In a 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.
Ordering Information
A complete part number is represented by the digits to the
right. For example, CM10S2030 is a MOLDED MINI-
DYAD™ with a minimum operate value of 10NI and a
maximum of 30NI. Refer to the switch operating specifica-
tion charts for available ranges. Special ranges are available
upon request.

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.

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.
(See detailed specifications for more information.)
