Trailer coupling with rest position locking device and detector unit

A trailer coupling comprising a ball neck which is movable between an operating position and a rest position with a pivot bearing body arranged on a first end and a coupling ball arranged on a second end, a pivot bearing unit fixedly arranged on a vehicle, by which pivot bearing unit the pivot bearing body is accommodated to be pivotable about a pivot axis between the operating position and the rest position, a rotation blocking device which, in the operating position, in a rotation blocking position, blocks a pivot movement of the pivot bearing body about the pivot axis and, in a releasing position, frees the pivot movement of the pivot bearing body, and a rest position locking device which, in an inactive position, permits a movement of the pivot bearing body relative to the pivot bearing unit and, in a locking position, non-rotatably fixes the pivot bearing body relative to the pivot bearing unit in the rest position, wherein associated with the rest position locking device is a detector unit which detects at least one active position of the rest position locking device, wherein the detector unit detects the at least one position of the rest position locking device by a magnetic field influenced by the at least one position of the rest position locking device.
