An arrangement for detecting a rotation of a rotary member

Arrangement arranged for detecting a rotation of an inside of a closed first housing (2) close to a housing wall of the rotary element having disposed on a substantially flat surface of the rotary member electrically conductive part surface (15), fixed which at least two, (to a transmitter connected or connectable sensor elements 10, 11, 18, 19) facing each capacitively coupled with rotation of the rotary member (3) over the electrically conductive partial surface (15), wherein the sensor elements (10, 11, 18, 19) on the outside of the housing wall (2) are arranged and on them patch or attachable electrically conductive connecting elements (8, 9) interlocking with the transmitter and / or non-positively coupled or can be coupled.
