An optoelectronic device for detecting labels with defined contrast patterns includes a transmitter for emitting light rays, a receiver for receiving light rays, as well as a deflection unit with a motor-driven polygonal mirror wheel. The transmitted light rays and the received light rays are guided over the polygonal mirror wheel in order to scan the labels and reassemble the label-reflected received light rays, respectively. The device furthermore is provided with an evaluation unit for evaluating electrical receiving signals converted from received light rays at the receiver. The motor for driving the polygonal mirror wheel has a drive shaft and is provided with a magnet that is an injection-molded part, which is formed onto the shaft and operates jointly with at least one coil.

Optoelectronic device

An optoelectronic apparatus for detecting objects in a monitored region includes a transmitter that emits transmission light, a receiver that receives a reflected light, and an evaluation unit, in which the transit time t of the transmission light that is guided in the monitored region and reflected back, as a reflected light, by an object is evaluated. The transmitter emits the transmission light in the form of a sequence of transmission light pulses. A portion of the light quantity of a transmission light pulse is coupled out as a reference transmission light pulse and guided by way of a reference path to the receiver. The transit time t of the reference transmission light pulse guided as a reference reflected light pulse to the receiver is determined in the evaluation unit. The transit-time difference t &minus;t is used to determine the distance of an object.
