Abstract: An optoelectronic sensor, in particular a laser scanner, for detecting objects in a monitored zone is provided, wherein the sensor has a light transmitter for transmitting transmitted light; a drive having a stator and a rotor; a scanning unit movable with the aid of the rotor for the periodic scanning of the monitored zone by the transmitted light; a light receiver for generating a received signal from light remitted by objects in the monitored zone; a control and evaluation unit for detecting information on objects in the monitored zone with reference to the received signal; and a base housing having a hood. The base housing and the hood have at least one interface for a mechanical connection to one another and the hood comprises at least one first bearing for mounting the scanning unit, with the scanning unit being rotatably supported with the rotor in the first bearing.

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.

Abstract: To achieve improved heat transfer of an optoelectronic sensor to its environment, the optoelectronic sensor comprises a rotating optical unit with at least one light transmitter for emitting light beams, at least one light receiver for receiving light remitted by objects in the monitored area, and associated electronics for controlling the optical unit, a drive unit for rotating the optical unit, a housing for enclosing at least the optical unit, the housing having at least one window region which transmits transmitted light beams and received light, and heat exchange elements provided on the outside of the optical unit and arranged in such a way that the heat exchange elements rotate with the optical unit and flat sides of the heat exchange elements lie at a defined distance from an inner side of the housing in order to provide convective heat exchange with the housing.
