The invention relates to a sensor device for producing signals that provide information as to whether an object, especially the limbs of a person, are present in an area of observation. The aim of the invention is to provide a sensor device which allows generation of measuring signals that have high informative value with respect to the presence of an object in an area of observation. For this purpose, a sensor device comprises a support structure extending along an area of observation. A plurality of detection sections is configured one after the other on the support structure for detecting detection events in the zone of observation defined by the respective detection section. The invention provides a monitoring circuit which allows an area of observation, extending along a boundary zone of some length, subdivided into small sections, for example a closing edge, to be monitored in an especially precise manner. |
