An optoelectronic sensor for safeguarding a hazardous area, such as a light grid, has a first and a second sensor part. The two sensor parts are arranged at a spatial distance from one another. Each sensor part has a plurality of transmitting elements for generating transmitted beams and a plurality of receiving elements for receiving the transmitted beams. In this way, a plurality of transmitted beams in opposite directions are formed between the sensor parts. Each sensor part has at least one evaluation circuit, which is coupled to the receiving elements of the respective sensor part. Each evaluation circuit is designed to generate a switch-off signal in a manner dependent on the respectively coupled receiving elements. In a preferred configuration, each sensor part has a plurality of evaluation circuits which are coupled to one another to form a series arrangement of evaluation circuits, and which are additionally coupled to a common data bus connection. |
