Abstract: An optoelectronic sensor for detecting objects in a monitored zone is provided, wherein the sensor has a scanning unit that is movable about an axis of rotation and that has a plurality of scanning modules accommodated therein for a periodic scanning of the monitored zone and for a generation of corresponding received signals and that has a control and evaluation unit for acquiring information on the objects from the received signals; and wherein the scanning modules each comprise a light transmitter for transmitting a light beam and a light receiver for generating a respective received signal from the light beam remitted by the objects. A respective mirror element is here associated with the scanning modules to set an angle of elevation of a respective scanning plane detected by a scanning module with respect to a central scanning plane perpendicular to the axis of rotation.
