DH Series Speed Sensors

The DH series are differential based, zero-speed, precision, single channel, speed sensors. At power-up, they calibrate themselves to the unique magnetic signature of their installed application and continue to update the calibration as the sensor is running. This unique combination of differential sensing technology and calibration make these sensors highly tolerant of installation misalignment, target geometry and composition, target run-out, vibration and air gap changes. The DH sensors sense each change in target movement, regardless of speed, from near zero to 15kHz, generating a steady pulse train of frequency proportional to target speed.
