Notice! You can find the corresponding declaration of conformity in the appendix of the manual. The manufacturer of the product, Leuze electronic GmbH & Co KG in D-73277 Owen/Teck, possesses a certified quality assurance system in accordance with ISO 9001.
The barcode reader BCL 34 is intended especially for the following areas of application: • labelling and packaging machines • space-critical barcode reading tasks • storage and conveying engineering, in particular for object identification on fast- moving conveyor belts • pharmaceutical industry BCL 34 Leuze electronic...
The BCL 34 uses a laser diode with low power in the visible red light range with an emitted wavelength of 650 … 690nm. CAUTION - the use of operating and adjusting devices other than those specified here or carrying out of differing procedures may lead to dangerous exposure to radi- ation! Leuze electronic BCL 34...

Only use sensors without switching output on pin 2 or sensor wiring configured without pin 2, as the switching output is not protected against feedback. For example, having the inverted sensor output incident on pin 2 leads to erroneous behaviour of the switching out- put. Leuze electronic BCL 34...
Contact assignment see page 41. Notice! It is recommended to connect the drain wire also to Pin 5 of the PROFIBUS connector. This ensures proper potential equalisation between the two connected devices. BCL 34 Leuze electronic...
In the standard setting, you can trigger a reading action via the switching input connection SWIN by connecting SWIN (pin 4) and VOUT (pin 1). Likewise, the BCL 34 can be activated via a Leuze sensor that is connected to the MS 34 105 through a standard sensor cable. Switching output The switching output connection between SWOUT (pin 2) and GND (pin 3) is normally open.
