Optoelectronic safety sensor for measuring distance and method for monitoring a surveillance area

摘要

The sensor (10) has a light receiver that generates a received signal based on light reception from the monitored zone (18). An evaluation unit determines and outputs the distance of detected objects (52a,52b) from the protected zone (48) based on the received signal and determines position of the detected objects to output securing signal on recognition of detected object into a protected zone. Independent claims are included for the following: (1) optoelectronic safety sensor system; and (2) method for monitoring of monitoring of monitored zone.
