Dyad(R) FR2 Features * Small size * SMT-compatible * Easily formed leads * Sputtered ruthenium contacts * Hermetically sealed contacts * Fast switching speed -- up to 500Hz * Wide range of available magnetic sensitivities Description Clare's DYAD(R) dry reed switches are ideally suited 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. Applications * Security * Proximity sensing * Smoke alarms * Automotive * Level sensor * Lamp current sensor * Relays Ordering Information A complete part number is represented by the digits to the right. For example, FR2S1030 is a DYAD(R) with a minimum operate value of 10 and a maximum of 30. Refer to the switch operating specification charts for available ranges. Special ranges are available upon request. FR2 S XX XX Minimum Operate Value (NI) Maximum Operate Value (NI) Surface Mount Dyad Refer to operating characteristics table for complete part number. Approvals * UL listed DYAD(R) Part # 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.

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.
