Abstract

A position sensor for motor vehicle is described that generates a varying pulse-width-modulated, position-dependent signal as a sensor signal, wherein an overall measuring range of the position sensor is divided into several similar,sequential measuring ranges. The position sensor according to the invention makes it possible to transfer sensor alignment to a receiver(s), so that alignment in or on the position sensor can be inexpensively replaced, without negatively influencing the resolution of the position sensor.
