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, is a MOLDED MINIDYADTM with a minimum operate value of 10NI and a maximum of 30NI. Refer to the switch operating specification charts for available ranges. Special ranges are available upon request."S" for straight switch blank for SMT Maximum operate value Minimum operate value
Surface Mount Molded Mini-DYAD Refer to operating characteristics table for complete part number.
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.Specifications
