Setup installation hall sensor

When installing a Hall sensor, make sure that the measured object (gear wheel) is within the maximum working distance. Furthermore, the sensor should be centricly aligned to the gear wheel. Observe the minimum wheel width to ensure sufficient signal reserves. Working distance and installation instructions refer to gear wheels with involute toothing (DIN 867).

Rotating direction of multichannel sensors

Two Hall semiconductor elements output two differentiated signals shifted by 90°per tooth and thus allow for picking up both rotating speed and direction of a gear wheel. A clockwise turning gear wheel will result in channel A being in lead to channel B.

Adjustment

To ensure proper two-channel output functionality, the Hall elements of multichannel Hall sensors must be arranged in alignment to the wheel’s tooth module. The sensor must be aligned to the teeth of the gear by aid of the coding keyway and under consideration of the gear module.
