Molded DYAD® CM15 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 Superior mechanical strength Enhanced for better auto placement Description Clare’s Molded 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. 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." • • • • • • • • • 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.

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.
