Title:
光電子センサ
Document Type and Number:
Japanese Patent JP4219442
Kind Code:
B2
Abstract:
The invention relates to an optoelectronic sensor having a light transmitter for the transmission of a transmitted light beam into a monitored region, having a light receiver for the reception of a received light beam, which is formed by the transmitted light reflected in the direction of the light receiver from an article in the monitored region, wherein the received light beam stands at a variable beam angle to the transmitted light beam in dependence on the spacing of the article from the sensor, and having a control and evaluation unit for the processing of the output signal of the light receiver. The invention includes a light receiver that has a multi-element light sensor which has at least four individual sensor elements, which are arranged adjacently in such a way that different sensor elements are illuminated by the received light beam in dependence on the beam angle.
