Abstract: A clamping mount for a sensor (500) has a clamping sleeve and a clamping nut (200). The clamping sleeve has a first section, in which the clamping sleeve is divided by slots into fins (112) extending parallel to its longitudinal axis, and a second section with an external thread (121). The clamping nut (200) has a first section in which the clamping nut has an internal thread with which it is screwed onto the external thread (121) of the clamping sleeve in such a way that the fins (112) are bent inwards into an interior space of the clamping sleeve. In a second section of the clamping nut, its inner lateral surface is angled inwards by an internal angle of at least 5°.

Abstract: A housing part (10) for a sensor has a transparent, hollow base body which has a toothing (14) in the form of a straight-toothed gearwheel in a circular-cylindrical emission region on its lateral surface. A circuit board of the sensor is partially arranged in the housing part (10). The circuit board has at least one light source which faces the emission region.

Abstract: An IO link module has at least one electrical terminal for connecting an electronic device and an electronic display device for displaying connection identification information of the at least one terminal. The display device is designed to permanently display the connection identification information free of a power supply using an electrical energy source which is independent of the IO link module.
