Ordering Information

Clare's Molded Ultra-Mini DYAD

is well suited for small,

signal switching applications. The small size lends itself
to surface mountable applications; working well on higher
density PC boards. The Molded Ultra-Mini DYAD

has

sputtered ruthenium contacts and an extraordinary seal
strength achieved by a patented laser sealing of the leads.
In low level or dry switching environments, switches
typically exceed 1 billion operations. 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.

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.

(1)

Consult factory for test procedure.

The reed switch shall be placed in the test coil with the gap centered in the core of the coil winding.
Test leads and their clips must be non-magnetic.
The longitudinal axis of the test coil and the test switch shall be vertical.

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.
