A logic controller is also developed by us to take
care of your various logic ideas suitable to your machine mechanism. The
logic controller accepts signals from print mark sensor & other proximity
sensors and gives required output as per the programmed logic.
A modulated green LED is focussed on the moving
packaging film. A highly sensitive photo cell continuously accepts the
reflections from the packaging film and sends the signals to the
electronic scanning circuit. On scanning the presence of Print Mark; it
gives transistorised output.
- Fully solid state thus making it a totally
reliable product. It further eliminates any sort of maintenance
- Immune to external light source, electrical
- A selector switch provided on the scanning
head, make it easy to choose mode of operation i.e. dark switching or
- High speed switching i.e. 2000 marks / min.
- Detection of any colour / colour sheds on any
background colour. A sensitivity pot is provided for this purpose.
