ABSTRACT:
A protective device for securing to a component movable along a track and for the monitoring of a protected zone moving with the component includes a light transmitter for the radiation of a divergent transmitted light beam into a spatial zone containing the protected zone, a light receiver for the reception of at least some of the light of the transmitted light beam of the light transmitter radiated into the spatial zone and for the emitting of corresponding received signals, and a restriction device which is arranged in the direction of a transmitted light path after a section of the transmitted light path which contains the protected zone and by means of which the transmitted light beam can be restricted to a less divergent received light beam defining the width of the protected zone in at least one direction.
