Abstract

The invention relates to a sensor element and to a path sensor constructed therefrom. The optical waveguide accommodated inside a supporting body, for example, a tube has to be placed in a defined position with regard to the elements of a board. In order to obtain a design that is both simple and easy to assemble, the invention provides that the head board, without its own surrounding housing, is fixed, for instance, glued directly inside a recess of the supporting body that is tubular for the most part.
