An optoelectronic sensor () is provided for detecting objects in a monitored zone (), in particular a laser scanner, which has a light transmitter () for transmitting a transmitted light beam (), a base unit () and a sampling unit () rotatable with respect to the base unit () for the periodic sampling of the monitored zone () by the transmitted light beam () and having a first circuit board (), a light receiver () for generating a received signal from the light () remitted by objects in the monitored zone () and an evaluation unit () for detecting information on objects in the monitored zone () with reference to the received signal. In this respect, the base unit () has a bearing () in which the first circuit board () is rotatably supported at its outer periphery with respect to the base unit ().

Optoelectronic sensor and method for detecting objects in a monitored zone

A focus adjustment apparatus () for a code reader () is provided which has an objective () having at least one lens and a drive () with a cam plate () for the positional adjustment of the objective (). The objective () is supported in a parallel guide () having a coupling unit () for the coupling of the cam plate () so that a rotational movement of the cam plate () adjusts the position of the objective () in the parallel guide () with a parallel shift of the objective plane. The coupling unit () has a press-on element () for the play-free coupling of the parallel guide () to the cam plate () and a counter-bearing element () between the press-on element () and the drive () for relieving the drive () from the press-on element ().
