1. An optoelectronic sensor for detecting objects in a monitored zone, comprising:
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 hood designed as a body of revolution with a side wall and a cover region and having a front screen as an outlet region for the transmitted light and an inlet region for the remitted light, the front screen being an integral component of the side wall of the hood,
wherein the base housing and the hood have at least one interface for a mechanical connection to one another,
and wherein 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 and the side wall of the hood comprises the first bearing.
