Print Mark Sensor

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 requirements.
  • Immune to external light source, electrical interference.
  • A selector switch provided on the scanning head, make it easy to choose mode of operation i.e. dark switching or light switching.
  • 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.

 

Supply Voltage 12 V DC / 24 V DC
Scanning Distance 3 to 8 mm between the scanning head and the film
Output High, Low, Open collector
Dimensions (LxWxH) 90 x 65 x 35 mm.

 

Print Mark Sensor can be used :

#    To drive DC relay

#    Can be coupled directly to any PLC / Logic Circuit

#    Can be used as an input for a Digital Counter / RPM
       Indicator etc.
