A sub-miniature, surface mount, close-differential, normally open switch with a 14.00mm long x 2.28mm diameter (0.551" x 0.090") glass envelope capable of switching 200Vdc at 10W. Available sensitivity range of 10-30 AT. High insulation resistance of 1010 ohms minimum and low contact resistance of less than 100 milliohms. Available in axial-leaded version (MACD-14). Ideally suited for position, proximity, float position sensing for liquid level, industrial controls, office equipment, home appliance, and telecom applications.
- Low close/open hysteresis (close differential)
- Surface mount normally open switch capable of switching 200Vdc or 0.5A at up to 10 Watts
- Available sensitivity range of 10-30 AT
- Hermetically sealed switch contacts are not affected by and have no effect on their external environment
- Zero operating power required for contact closure
- Excellent for switching micro-controller logic level loads
