FR2259

Dyad® 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® 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.
