4.1 On the barcode readers BCL 34
The bar code readers BCL 34 are high-speed scanners with integrated decoder for all bar
codes currently in use, e.g. 2/5 Interleaved, EAN etc.
The many possible configurations of the device via PROFIBUS modules permit its adapta-
tion to a multitude of reading tasks. Due to the small dimensions of the unit and the short
minimum reading distance, the BCL 34 may also be used in highly constrained spaces.
A special barcode reader with optics version J is available for all ink jet applications. This
reader has been optimised for low contrast barcodes that generally feature gaps. Further-
more, device variants with integrated heating are available.
Information on technical data and characteristics can be found in chapter 5.
AutoReflAct
AutoReflAct stands for Automatic Reflector Activation and permits an activation without
additional sensors. This is achieved by directing the scanner with reduced scanning beam
towards a reflector mounted behind the conveyor path. As long as the scanner is targeted
at the reflector, the read gate remains closed. If, however, the reflector is blocked by an
object such as a container with a barcode label, the scanner activates the read procedure,
and the label on the container is read. When the path from the scanner to the reflector has
cleared, the read procedure has completed and the scanning beam is reduced and again
directed onto the reflector. The reading gate is closed.
