An inductive linear displacement sensor arrangement includes a movable coupling device coupled to a movable body, an electrically conductive coupling element, and a stationary circuit carrier. The circuit carrier includes an excitation structure and a receiving structure, which extend along a displacement path of the coupling device. An evaluation and control unit is designed to evaluate a measurement signal induced in the receiving structure and to determine the current position of the coupling device and of the body. The coupling device comprises a slider on which the electrically conductive coupling element is arranged. The slider is mounted for sliding movement in a plane of displacement via the path of displacement of the coupling device on two parallel guide elements, one of which guides the slider of the coupling device along the displacement path, and another of which is a sliding guide which prevents the slider from tilting and/or twisting.
