Sentrol Switches from Alarm Service & MaintenanceDesigned to make installation easier, these position sensors have earned their reputation for quality. They are built for durability and dependability. Most are conservatively rated at 100,000 cycles under full load, and 10,000,000 cycles under dry circuit.

Every reed connection is hand soldered and the reeds in all models are environmentally sealed. Like the GuardSwitch™ safety interlock switches, our position sensors are tested before they leave the factory – 100% of the time.

Our world-class manufacturing standards and attention to detail virtually eliminate all out-of-box failures. You can install the position sensors quickly and with every confidence in their reliability.
