- a disk 103 or a part 105 of the movable part 101 can also be understood as a movable part 101.
- FIG. 9 shows a further aspect of the invention, namely a structural component 107, for example in the form of a B-pillar, for a vehicle 1, having: a receiving seat 102 for a sensor device 100 for actuating a movable part 101 of the vehicle 1, wherein the sensor device 100 can be designed as described above.
- a structural component 107 for example in the form of a B-pillar, for a vehicle 1, having: a receiving seat 102 for a sensor device 100 for actuating a movable part 101 of the vehicle 1, wherein the sensor device 100 can be designed as described above.
- a sealing frame 104 in particular an outer edge of the printed circuit board 20, can be provided on the sensor device 100 or on the receiving seat 102 (be it on the movable part 101 or on the structural component 107), in particular an outer edge of the printed circuit board 20, in order to to seal the area between a front side of the sensor device 100 and the support surface in the receiving seat 102.
- a pad 98 can be provided, which can have a corresponding opening for the lighting unit 60.
- a vehicle with a corresponding sensor device 100 also represents an aspect within the scope of the invention.
