Optoelectronic sensor and process for detection of an object in a monitored area

摘要

An optoelectronic sensor, especially a reflection photoelectric barrier and a reflection light sensing device, for detection of an object ( 2 ) in a monitored area, with a housing ( 3 ) with transmitting and receiving optics ( 6 ) and with an evaluation circuit ( 10 ). The optoelectronic sensor has an especially simple structure in that there is only one single optoelectronic transmitting and receiving component ( 14 ) which sequentially acts as both the opto-transmitter and the opto-receiver in succession in time.
