Optoelectronic sensor assembly and method for monitoring a surveillance area

摘要

The photoelectronic sensor device has multiple light transmitters arranged parallely in a light transmitter bar that radiates light in a transmitting cone in a monitored area. The multiple light receivers (31) are provided in a photoelectronic sensor device and are arranged parallely in a light receiver bar that receives light from a receiving cone of the monitored area, and has a resolution range element (41). A control unit is provided with a medium for determining light impact points (L1) of the transmitting cone of the light transmitter and different light sources of the light receiver. An independent claim is also included for a method for monitoring a monitoring area with multiple light transmitters arranged parallely in a light transmitter bar.
