Industrial Geartooth Speed Sensors & Direction Sensors
Industrial geartooth speed and direction sensors are devices which are used to measure the speed with which a gear is moving and also the direction of the movement. The inclusion of two Hall Effect magnetic field cells allow for both the speed and direction to be detected within a single unit. Our geartooth speed and direction sensors are produced by ZF and manufactured to the highest standards.

Gear-tooth speed and direction sensors are a type of electrical sensor that is used to detect and measure the speed with which a gear is moving and the direction of the movement.
Gear-tooth sensors work by utilising the Hall Effect principle. By using two Hall Effect magnetic field cells placed near to the gear-teeth of the gear that is to be measured, the movement of the gear tooth passing the magnets distorts the magnetic field. This distortion is picked up by the sensor and the output signal can be used to calculate the gear’s speed and direction of movement.
There are a few different types of Hall Effect gear tooth sensors. These are designed to measure the speed of a gear, the speed and direction of a gear, counting rotational movement, position tracking of a gear, monitor the alignment of a gear or quadrature variations of these.
