In a device for sensing the position of a shift fork in a transmission, the shift fork is connected to a piston rod of a shifting piston which is guided axially in a shifting cylinder. The shift fork engages an axially slidable sliding sleeve, which slides on a transmission shaft, to engage or disengage a transmission stage. A magnet functioning as a signal generator is arranged on an actuating element, such as the switching piston, piston rod or shift fork. A 3D Hall sensor positionally fixed relative to the magnet functions as a signal receiver, sensing a magnetic field generated by the magnet. An electronic control unit connected to the 3D hall sensor determines the position of the shift fork from the relative positions of the magnet and 3D Hall sensor and transmits the position as a signal, taking into account linear, rotational, and/or pivoting movements of the actuating element.

A cable adapter () for collecting and forwarding analog signals from a plurality of sensors () in a motor vehicle (), in particular brake lining wear sensors of a utility vehicle disc brake, has first and second signal input terminals () for connecting the cable adapter () to sensors () and for receiving signal currents (). The cable adapter () has a signal output terminal for connecting the cable adapter () to an electronic control unit () of the motor vehicle () and switching electronics () that are configured to transmit the first and second signal currents (') to the signal output terminal () at a predetermined rhythm.

A monitoring device for a disk brake includes a sensor configured to be attached to a brake caliper of the disk brake; and a measuring element configured to be moved relative to the sensor unit. The sensor is designed to register a relative position of the measuring element. The sensor and the measuring element are spaced from one another for the purpose of forming a contactless monitoring device. The preloading element is arranged between the measuring element and the sensor for preloading the measuring element against a pressure spindle of the disk brake.
