These sensors use resistors that are sensitive to magnetic fields. When a rotor with magnetic poles is sensed, a sine wave is generated which is then converted to a square wave. This pick-up is more sensitive and thus can operate from 2 to 8192 PPR depending on the model being used. They require a power supply which permits operation down to zero speed and can drive cable lengths up to 2000 feet!
Our partner's Wide-Gap magnetoresistive technology resists interference from motors and brakes, and eliminates sensor scraping damage.
