Optoelectronic sensor with light sensor for transmitting light beam in monitoring region - has light receiver having multielement light sensor with at least four adjacent sensor elements with different elements acted on depending on beam angle

摘要

The optoelectronic sensor (1) transmits a light beam (8) in a monitoring region, and has a light receiver for receiving a light beam (10) reflected from an object (9,9'), which is at a variable angle to the transmitted beam, depending on the distance (D,D') of the object from the sensor. The output signal of the receiver is processed in a control and evaluation unit (7). The light receiver has a multielement light sensor (5), with at least four individual sensor elements, which are arranged next to each other. Different sensor elements are acted on by the reflected beam, depending on the beam angle. The control and evaluation unit includes devices by which the sensor elements are subdividable in a variable manner into several, especially two or three sensor regions. Preferably, there are between eight and 1024 sensor elements.
