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."

Features

Description

Applications

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.

Ordering Information

A complete part number is represented by the digits to the

a minimum operate value of 10NI and a maximum of 30NI.

Refer to the switch operating specification charts for avail-

able ranges. Special ranges are available upon request.

Surface Mount Molded DYAD

Refer to operating characteristics table for complete part number.

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.
