Camshaft sensor wheel

A sensor wheel for detecting the rotational position of a camshaft, elevations and depressions being developed along the circumference of the sensor wheel, which respectively form a segment, which may be detected by a sensor sensitive to magnetic fields when the sensor wheel is in motion, the sensor wheel comprising a long elevation, a medium length elevation, a short elevation, a long depression, a medium length depression, and a short depression, the long elevation being as long as the long depression, the medium length elevation being as long as the medium length depression, the short elevation being as long as the short depression, wherein a ratio of a length of the long elevation to a length of the medium length elevation is the same as a ratio of the length of the medium length elevation to a length of the short elevation;

• wherein the length of the long elevation is greater than the length of the medium length elevation, and the length of the medium length elevation is greater than the length of the short elevation.
