Actuating device for an internal combustion engine with magnetic angel sensor

The device has two magnetic cuboids (24, 25) arranged in a position at an output shaft and standing in functional connection to a contact less sensor. A surface of the cuboid (24) has an opposite polarity as the surface of the other cuboid, where the distance from the sensor to the shaft is larger than the distance of the cuboids to the shaft. The sensor and cuboids are arranged in a common plane arranged perpendicular to the shaft.
