Abstract
An actuating device (10) for an automated manual transmission (12) includes a pressure-medium-operated actuator (54) having a piston (58) and a piston rod (64) connectable to the selector element or shift element of the manual transmission. The piston is arranged in a cylindrical receiving chamber (50) of the housing (18) of the actuator and is coaxially movable therein. A sensor system (30)includes a magnet (38) arranged on a holding device (44) and a magnetic-field-sensitive sensor (32) is arranged on the housing radially with respect to the magnet (44).The holding device has a hollow cylindrical geometry, an anti-rotation element (80)is form-lockingly accommodated in an associated recess in the housing (18), and that the anti-rotation element extends across the holding device in the manner of a secant such that rotational movement of the holding device is blocked, although axial and rotational movement of the piston are possible.
