Abstract
A sensor is provided comprising at least one transmitter for transmitting a transmission signal; at least one receiver for generating a received signal from the transmitted signal reflected back by the objects; a base unit; a scanning unit movable about an axis of rotation with respect to the base unit for a periodic scanning of the monitored zone; and a control and evaluation unit for detecting information on the objects with reference to the received signal, wherein an inductive energy transmission unit is provided between the base unit and the scanning unit that comprises a first guide element of the base unit and a second guide element of the scanning unit for guiding the magnetic field of the inductive energy transmission; and wherein the guide elements have an L-shaped cross-section. In this respect, the guide elements are divided into at least two respective guide segments in the peripheral direction.
