Technical content
www.clare.com Molded Mini-DYAD™ 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. Surface Mount Molded Mini-DYAD Refer to operating characteristics table for complete part number. 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. (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.

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.
