Abstract

The inventive device consists of a first part (1) and a second part (2). Said parts (1, 2) can be displaced in relation to each other. The first part (1) has at least one exciting coil (3) which generates a magnetic flux which is substantially guided in at least two elements (6, 7) of the first part (1) and at least partially according to the relative position between the first and second part (1, 2) via at least two elements (2a, 2b) of the second part (2). The first part (1) also comprises at least two sensor coils (4, 5) which are respectively arranged around at least one element (6, 7) of the first part (1). According to the invention, the elements (6, 7) of the first part (1) are arranged in such a way in relation to the elements (2a, 2b) of the second part (2) that the signals can be phase shifted on the sensor coils (4, 5), whereby the second part (2) is constructed in a symmetrical manner with respect to a plane of symmetry which is perpendicular to the elements (2a, 2b) of the second part (2).
