ABSTRACT:
A rotation angle detector for detecting the angular position of a shaft, i.e. a camshaft or a camshaft of an internal combustion engine, includes a rotatable detector wheel coupled to the shaft. Markings of a first type are distributed along a periphery of the detector wheel and are detectable by a sensor for determining a relative rational angle. Markings of a second type are also distributed over the periphery of the detector wheel. The markings of the second type are distinguishable from each other for determining an absolute rotational angle of the shaft or for determining selection of a combustion chamber for injection.
