Abstract
An optoelectronic sensor for the detection of objects in a monitored zone is provided that has a light transmitter for transmitting a light beam, a light receiver for generating a received signal from the light beam remitted by the objects in the monitored zone, a control and evaluation unit for the detection of information on the objects with reference to the received signal, a base unit, a scanning unit movable with respect to the base unit for the periodic scanning of the monitored zone, and a drive having a hollow shaft for moving the scanning unit, wherein the scanning unit comprises a first data transmission unit and the base unit comprises a second data transmission unit to exchange data wirelessly between the base unit and the scanning unit through the hollow shaft, The first data transmission unit and the second data transmission unit are configured as microwave units for the data exchange by means of microwave signals.
