Digital TMR Rotation/Speed Sensor

Crocus magnetic rotation/speed sensors detect rotating shaft speed. The digital CT572 detects magnets imbedded in a shaft-mounted pulser wrap/disc. As the shaft rotates, the passing magnets are detected across the air gap as digital pulses with the frequency proportional to the shaft RPM. The CT572 rotation/speed sensor is based on Crocus’ patented TMR sensor technology, Magnetic Logic Unit™ (MLU™)
