Guest I need a bar code system that serves as a counter to monitor a specific bar code. When it detects a different bar code it sends an electric signal to stop a small bag sealer machine (URANIA sealer machines). The main purpose is to eliminate incorrect product mixing.


Your application sounds like a fully automated system that may be working at relatively high speeds. For these types of applications and the ability to connect to other electronic systems I would suggest looking at the Cognex lines of fixed scanners. The Dataman 100 is very aggressive in reading 1D bar codes and has 2 opto-isolated outputs to trigger external devices like your sealer machine.
