Abstract: A connector module for the connection of a sensor, such as an optoelectronic sensor, to a fieldbus, having a sensor interface for the connection of the connector module to an interface of the sensor, a bus interface for the connection of the connector module to an interface of a fieldbus and a circuit for the exchange of data to receive data from the sensor interface and to convert them with respect to their format and to output the converted data at the bus interface. The circuit for the exchange of data includes a memory for the intermediate storage of a sensor-specific control file or description file received from the sensor interface, with the control file or description file being able to be processed in the circuit such that the connector module shows the behavior of the respective connected sensor with respect to the fieldbus.

Abstract: A device for optical scanning of markings, such as barcodes, has at least two transmitters (10, 20) that send light beams (12, 22) at different angles toward a rotating polygonal mirror (30), which deflects the light beams onto the markings being scanned. The light reflected by the markings is deflected by the polygonal mirrors (30) to separate receiver systems, so that the device has and simultaneously uses at least two separate transmitter/receiver channels.

Abstract: A method and an apparatus for the optically scanning of objects, especially markings, use at least two emitters (10; 20) arranged so that light beams (12; 22) emitted by them sample or scan the object at different angles. The at least two emitters (10, 20) are arranged so that the emitted light beams (12, 24) strike reflecting surfaces (32) of a polygonal mirror (30) at different angles to a plane (36) that is perpendicular to an axis of rotation of the polygonal mirror, and which direct the beams onto the object being scanned so that the beams strike the object at different angles. The polygonal mirror (30) directs the beams reflected by the object onto an associated, separate receiver system to form at least two separate emitter/receiver channels.
