Patent ID: 8319172

Claim:
An optoelectronic sensor ( 10 ) having a transmitter ( 12 ) for operating light, a light receiver ( 14 ) for the generation of an electrical received signal from incident light and an evaluation unit ( 16 ) which can detect an object in the beam path from the transmitter ( 12 ) for operating light to the light receiver ( 14 ) from the received signal, wherein a first alignment light transmitter ( 13 a ) is provided, characterized by a second alignment light transmitter ( 13 b ), with the first alignment light transmitter ( 13 a ) and the second alignment light transmitter ( 13 b ) being able to be individually activated and the evaluation unit ( 16 ) being designed to determine alignment information on the adjustment of the sensor ( 10 ) from a received first alignment signal of the light receiver ( 14 ) with an activated first alignment light transmitter ( 13 a ) and from a received second alignment signal of the light receiver ( 14 ) with an activated second alignment light transmitter ( 13 b ) wherein the light receiver ( 14 ) has a single common light reception element; and wherein a respective received signal can be generated by multiplexing by selective activation of the transmitter ( 12 ) for operating light or of one of the alignment light transmitters ( 13 a , 13 b ).
