    Abstract: Disclosed is an arrangement for detecting rotational speed of a wheel or any other rotating body by a sensor (1, 6), which is coupled via a magnetic field to an encoder (23) that rotates with the rotating body. If a slot between sensor element (S1, S2) and encoder (23) becomes too small in the prior art arrangements, flipping and, hence, doubling of the measured rotational speed of the wheel can occur. This caused problems in safety devices of a vehicle, which require a correct indication of the wheel rotational speed for proper operation. To improve the tolerance with respect to the mounting position of the known arrangements, two separated signal paths (S1, f1; S2, f2) are provided with sensor elements (S1, S2) of differing sensitivity.
