Sentrol Industrial 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 modes are environmentally sealed. Edwards Signaling non-contact interlock switches are developed and manufactured by the market leader for industrial applications. We produce a full line of interlock and position sensors providing solutions for your machine guarding and sensing needs.
