Circulating ring rotation detecting device for bearing i.e. antifriction bearing, of vehicle wheel, has reed switch arranged in proximity of magnet, and magnet arranged between coding wheel and reed switch
The device has a coding wheel containing a ferromagnetic active section exhibiting material discontinuity and/or material thickness changes. The coding wheel is arranged on a circulating element opposite to an idle receiver arrangement. A reed switch (1) is arranged in a proximity of a magnet in such a manner that a position of the reed switch depends on an angular position of the coding wheel. The magnet is arranged between the coding wheel and the reed switch. A printed circuit includes an electronic circuit to process an output signal of the reed switch.
