Abstract: A wheel bearing sensor for measuring rotary motion of a wheel includes a signal generator ring that rotates with the wheel and a sensor-accommodating housing, which is a rotation-symmetric element, such as a deep drawn sheet-metal part. This housing accepts a speed sensor in a sensor insertion side and retains the sensor in a fixed position.

The pole shoes are designed, arranged and conformed to one another so that, whenever the end piece of a pole shoe points to a tooth or a projection, the second, diametrically opposite end of the pole shoe is directed to a tooth gap or depression. The measuring coil core is made up of at least two permanent magnets which are magnetized perpendicularly to the coil axis and respectively embedded between two pole shoes.

Provided as signal generator ring is a toothed wheel with inwardly directed teeth or several toothed wheels firmly coupled with one another.
