Mini-Dyad™ MN2 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 Mini-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, MN2S1030 is a MINI-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.
