Abstract
The present invention relates to an angle sensor of the capacitive type, in particular for a steering column of a motor vehicle having a stator and rotor element, comprising at least one sensor element (200) of the stator and a transmitter suitable for applying electrical signals to a transmitter one of the elements, and a receiver suitable for detecting the signals received on a receiver one of the elements, which signals depend on the angular position of the rotor element (300) relative to the sensor element (200) of the stator, the sensor being characterized by the fact that the sensor element (200) of the stator is placed in a box (100) organized to be engaged sideways onto the assembly (10, 50) in which the rotor element (300) is received.
