Quadrature Speed and Direction
Geartooth Sensors

Quadrature Sensors provide two 90º out of phase digital outputs to record speed and direction of travel of gear teeth or other ferrous targets past the sensor.

Hall effect circuitry measures speed accurately to true zero, direction of rotation or travel, and true angular position of gear. Built to stand up to hostile environments, including a wide range of operating temperatures.
The parts shown herein are typical models and are not intended to limit your options. Specifications can be modified to suit your specific application.
