A sub-miniature, surface mount, normally open switch with a 15.24mm long x 2.54mm diameter (0.600" x 0.100") glass envelope. Capable of switching 200Vdc at 20W with close-differential characteristics. Available sensitivity range of 17-38 AT. High insulation resistance of 1010 ohms minimum and contact resistance of less than 100 milliohms. Available in axial-leaded version (MLRR-4). Ideally suited for reed relays, security, metering, limit sensing, telecom and office equipment applications. Will handle lamp loads up to 2W @ 14V with no suppression circuitry.
- Low close/open hysteresis (close differential)
- Surface mount, normally open switch capable of switching 200Vdc or 1.0A at up to 20 Watts
- Available sensitivity range of 17-38 AT
- Hermetically sealed switch contacts are not affected by and have no effect on their external environment
- Zero operating power required for contact closure
