1. A round plug (1) for industrial applications in the automation industry, comprising a printed circuit board (20) in the interior of the round plug (1) with a sensor element (21) arranged on the printed circuit board (20), an evaluation circuit (22) applied onto the printed circuit board (20), an interface (S), a collar surface (30) located at the circumference of the round plug (1), an axis of rotation (31) and a sleeve type adjustment element (10) partially rotating about the axis of rotation (31);
wherein the sleeve-type adjustment element (10) comprises an inner sleeve (11), an outer sleeve (12), a spring wire (13) and a magnet (14), and wherein the magnet (14) is introduced into the outer sleeve (12); the adjustment element (10) being pressed onto the round plug (1) in such a way that the inner sleeve (11) is firmly and form-fittingly connected to the collar surface (30) of the round plug (1); wherein the movable parts of the adjustment element (10), the outer sleeve (12) and the magnet (14) assume a basic position (G) in the spring equilibrium of the spring wire (13); wherein the sensor element (21) is able to detect the basic position (G) and can distinguish a first direction of rotation (A) from a second, opposite direction of rotation (B) when the adjustment element (10) is rotated out of the basic position (G).
