    Abstract: The invention relates to a sensor arrangement on a steering column (2) of a motor vehicle and consists of at least two sensors (10, 11, 20, 21) for redundant capture of the torque applied to the steering column (2) and/or for capture of the rotation angle of the steering column (2). The sensors (10, 11, 20, 21) of the sensor arrangement (9) are connected to a power supply (VDD, GND) via electrical lines (30, 31, 32, 33), each of the sensors (10, 11, 20, 21) transmitting data to a controller (8) via a signal line (16, 17, 26, 27). In order to reduce the number of connecting cables to the controller (8), provision is made for the signal lines (16, 17, 26, 27) from two sensors (10, 11, 20, 21) to be connected to the controller (8) via a common data line (34, 35, 36). Each sensor (10, 11, 20, 21) can be individually actuated by the controller (8) via the data line (34, 35, 36) and the signal line (16, 17, 26, 27) such that a signal (53) from the controller (8) prompts the addressed sensor (10, 11, 20, 21) to output its data to the controller (8) via the signal line (16, 17, 26, 27) and the data line (34, 35, 36).
