Sensor device for detecting a rotational position of a rotor of an electric machine, drive device, pressure generator for a brake system

A sensor device for detecting a rotational position of a rotor of an electric machine. The sensor device has at least one sensor element and at least one electronic component connected electrically to the sensor element. The sensor element and the electronic component are disposed on one common printed circuit board of the sensor device. The printed circuit board has at least a first rigid board part, a second rigid board part, and a flexible board part. The second rigid board part is joined to the first rigid board part by the flexible board part. The sensor element is disposed on the first rigid board part, and the electronic component is disposed on the second rigid board part.
