Abstract: The circuit arrangement comprises at least two movable elements (1 to 3) which are to be monitored and which are assigned a sensor (4 to 6) in each case. The output signals of the sensors (4 to 6) are fed to an evaluation circuit (7) via a common connection. The evaluation circuit (7) has only a single input for receiving the signals of the sensors (4 to 6). Each sensor (4 to 6) emits a pulse shape characterizing the connected element. The pulse shapes of the pulses generated by the sensors are configured in such a way that the evaluation circuit can uniquely identify the individual pulses, even in the case of superimposition.
