Abstract: An optoelectronic sensor (10) is provided for the detection of objects in a monitored zone (20) that has a light transmitter (12) for transmitting transmitted light (16), a laser scanner (26) for generating a received signal from received light (22) from the monitored zone (20), a movable deflection unit (18) for the periodic deflection of the transmitted light (16) and of the received light (22), a control and evaluation unit (32) for the detection of information on objects in the monitored zone (20) using the received signal, and an optical deflection element (18, 40), in the optical path of the received light (22), In this respect, the deflection element (18, 40) has temperature dependent beam shaping properties.

Abstract: A heatable cover for an optical sensor comprises a transparent cover element, a transparent and electrically conductive coating that is arranged at the cover element, and at least two electrodes that are spaced apart from one another and that are each in contact with the conductive coating. A respective distance between a respective two of the electrodes is defined along a respective distance line across the coating. Each of the at least two electrodes further has at least one contacting position at which the respective electrode is connected to a voltage source. The contacting positions of a respective two electrodes are spaced apart from one another in a direction that extends at a right angle to the distance line.
