Abstract
A rotary actuator has a handle, rotatable about an axis of rotation, and a position sensor system for detecting the rotary position of the handle. The rotary actuator has an actuating segment is made of an electrically conductive material and, forming a capacitor, is opposite a sensor segment of a stationary segment ring, which is concentric with respect to the axis of rotation 3 and consists of a plurality of sensor segments. The sensor segments include an electrically conductive material and are axially spaced apart by an air gap. A sensor line leads from each sensor segment to evaluation electronics.

A rotary actuator, comprising:
- a handle rotatable about an axis of rotation;
- a position sensor system for detecting a rotary position of the handle;
- an actuating segment located at an end of the handle facing away from an operating side of the handle and at a radial distance from the axis of rotation, the end of the handle including an electrically non-conductive material, wherein the actuating segment includes a first electrically conductive material and forms a capacitor;
- a stationary segment ring including a plurality of sensor segments uniformly distributed on a periphery of the segment ring and being concentric with respect to the axis of rotation, wherein:
- the actuating segment is located opposite the sensor segments,
- the sensor segments are spaced apart from one another in a circumferential direction and are made of a second electrically conductive material, and the sensor segments are spaced apart from the handle by an air gap;
- and
- a respective sensor line leading from each sensor segment to evaluation electronics.
