Abstract

An optoelectronic sensor for recognizing object edges of objects moved relative to the sensor, has a light transmission device with at least one light transmitter, in particular at least two light transmitters, for generating a respective collimated or focused transmitted light beam. The sensor has at least two light receivers for imaging a light spot produced by the respective transmitted light beam on an object, wherein the two light receivers are arranged on two mutually opposite sides of the light transmission device, and has an evaluation unit which is designed to compare the two reception intensities of the two images of the respective light spot taken by the two light receivers with one another and to evaluate the result of the respective comparison to recognize an object edge.
