Abstract:
The invention relates to an optoelectronic sensor for monitoring a monitored zone. The sensor comprises a main light transmitter for transmitting sensing light signals that propagate through a protective screen into the monitored zone; a main light receiver for receiving light that emanates from the monitored zone; and a control unit for controlling the sensor. The sensor is configured in this respect to carry out a contamination recognition in which the degree of contamination of the protective screen is determined by means of a measured contamination value. The sensor in accordance with the invention is characterized in that the control unit is adapted to recognize the approach of a hand and/or of a finger toward the protective screen with reference to the contamination recognition and to output an action signal on the recognition of the hand and/or of the finger.
