Dyad® SRC FR2 DEVICES 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 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. 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® 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® 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.
