ABSTRACT:
An optical sensor arrangement includes a transmitter that emits light rays and a receiver that receives light rays reflected from an object. A deflection unit deflects the transmitted light rays to periodically sweep across a monitoring range. An evaluation unit stores parameters of several safety zones that form respectively predetermined areas of the monitoring range. An object detection signal is generated in the evaluation unit in dependence on receiving signals at the receiver output, which object detection signal indicates whether or not an object is located within an activated safety zone. A communication interface is coupled to the evaluation unit and is operative for bi-directional data transmission with an external unit. At least one of the stored safety zones is activated by reading into the evaluation unit activation signals from the external unit via the communication interface.
