Es ist von Vorteil, dass der Geber auf der Welle angeordnet ist, die in der Hohlachse eingeführt ist, wobei die Welle mit dem Pedal derart gekoppelt ist, dass der Geber durch das Pedal bewegt wird. Dafür kann insbesondere ein Mitnehmerelement verwendet werden, das beispielsweise in die Welle eingepresst ist und am Pedal angeschraubt ist. Beispielsweise kann dafür ein sogenanntes Mitnehmerblech verwendet werden. Das Mitnehmerblech befindet sich auf derselben Seite oder auf der gegenüberliegenden Seite der Welle, an der der Geber angeordnet ist. Der Geber kann dabei auf der Welle aufgeklebt, eingepresst oder durch eine stoffschlüssige Verbindung oder kraftschlüssige Verbindung oder formschlüssige Verbindung befestigt sein.

It is advantageous that the encoder is arranged on the shaft, which is inserted in the hollow axle, wherein the shaft is coupled to the pedal such that the encoder is moved by the pedal. For this purpose, in particular, a driver element can be used, which is for example pressed into the shaft and screwed to the pedal. For example, a so-called drive plate can be used for this purpose. The drive plate is located on the same side or on the opposite side of the shaft on which the encoder is arranged. The encoder can be glued on the shaft, pressed or by a cohesive connection or non-positive Attached connection or positive connection. The encoder is thus arranged on the end face of the shaft opposite the sensor element only separated by the air gap. The encoder can be arranged in a recess of the shaft and, for example, only partially protrude beyond the shaft.
