The assembly includes a first element and a second element, wherein the elements are fastened to one another in such a way that they together enclose an assembly interior, and wherein an electrically conductive cable protrudes into the assembly interior through a cable passage formed between the elements. For forming a particle seal assigned to the cable passage, at least one of the elements has at least one projection, which projects in the direction of the other element and presses the cable against the other element.

Abstract: An inductive sensor arrangement for detecting a movement of a movable body includes a movable coupling device coupled to the movable body and a measured-value detection device comprising a circuit carrier with an exciter structure and a receiving structure. The exciter structure is coupled to an oscillator circuit which, during operation, couples a periodic alternating signal into the exciter structure.
