- the actuating element 7 can, for example, be a permanent magnet, the magnetic field of which is able to actuate the sensor 3 in such a way that it emits at least one sensor signal, on the basis of which the current position of the component 6 can be determined.
- the support part 1 formed in the present case by the housing part 4 is preferably cylindrical on the outside and, in particular, has a circular cylindrical contour.
- the sensor 3 forms an inseparable integral part of the fastening device 2, which is attached to the cylindrical outer surface 12 of the support part 1 such that it extends over at least 180 of the circumference of the support part 1. In this way, the sensor arrangement can be produced very easily on the one hand while realizing compact dimensions and on the other hand also very easily and securely attached to the supporting part 1.
- the fastening device 2 is designed as a fastening ring which completely surrounds the supporting part 1 in the state attached to it and is non-positively clamped to the outer surface 12 of the supporting part 1, so that it is immovably fixed relative to the supporting part 1.
- the fastening device 2 in the exemplary embodiment consists entirely of plastic material and has flexible properties over its entire length measured in the circumferential direction of the supporting part 1.
- the ring structure of the fastening device 2 is interrupted at one point, so that an elongated, band-like part is obtained which is placed around the support part 1 during assembly such that the two end regions, hereinafter referred to as tension arms 14, 15 denotes come to lie adjacent to each other in a closure region 13.
- tension arms 14, 15 By means of a tensioning device 16 placed in the closure area 13, the tensioning arms 14, 15 can be connected to one another while closing the ring structure and, in the sense of a reduction in the cross section enclosed by the fastening device 2, pulled together so that the
- Fastening device 2 is firmly clamped around the supporting part 1.
