Abstract
An optical sensor includes a sensor housing having a through-opening that connects a housing interior and that has an opening longitudinal axis, a guide rod that is guided in an axially displaceable manner in the through-opening and that projects into the housing interior, and a reflective-surface carrier that is accommodated in the housing interior and that is motionally coupled to the guide rod and has a diffusely reflecting, reflective surface. The sensor also includes a light-emitting element and a light-receiving element, which are both disposed in a stationary manner relative to the sensor housing and are at a distance from the reflective surface that is dependent on the axial position of the reflective-surface carrier.
