1 / 4 page SRC Devices DYAD® 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. Features Description • 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 Applications Approvals • Security • Proximity sensing • Smoke alarms • Automotive • Level sensor • Lamp current sensor • Relays • UL listed 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 right. For example, FR2S1030 is a DYAD® 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. Surface Mount Dyad Refer to operating characteristics table for complete part number. Maximum Operate Value (NI) Minimum Operate Value (NI) FR2 SXXXX Dyad® (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.
