Print Mark Sensor

Product Details:

Print mark sensors are used for sensing registration mark on packaging film. These Electronic sensors include state-of-the-art technologies for providing precision results. These Electronic sensors are used in various industrial segments.

Working Principle
This is designed for sensing Registration Marks. It continuously scans the presence of registration mark on the moving packaging film. The electronic circuitry is capable of detecting / scanning any colours on any Background colour. A modulated, Green LED is focused on the moving packaging film. A highly sensitive Photo cell continuously accepts the reflections from the film (paper / plastic) and sends the signals to the electronic scanning circuit. On scanning the presence of Registration Mark; it gives transistorised output.

A logic controller is also provided which accepts signals from scanning head & other Proximity Sensors to keep correct pouch / bag length by driving correction motor (110V AC, 4wire) or (230VAC, 3 wire).

Salient Features

• Fully solid state thus making it totally reliable.
• Immune to external light source, electrical interference.
• A selector switch provided to choose Dark switching or light switching.
• High speed switching i.e. 2000 marks/min.
• Detection of different contrast sheds by means of sensitivity pot provision.

Print Mark Sensors With Teach – In Function
This is with micro controller based technology, wherein user has to press SCAN key (a feather touch key), keeping White spot light on Mark colour as well as on background colour and within 2-3 sec both colours will get registered in memory. The electronic scanning circuit then differentiate both colours and gives out put on detection of Registration Mark.

1. Print Mark Sensors

   This is designed for sensing Registration Mark. It continuously scans the presence of registration mark on the moving packaging film. The electronic circuitary is capable of detecting any colours on any background colour. The scanning rate is as high as 2000 packages / minute making it suitable for any type of packaging machine including candy packing machine.

2. WORKING PRINCIPLE

   A modulated, Green LED is focused on the moving packaging film. A highly sensitive Photo cell continuously accepts the reflections from the film (paper / plastic) and sends the signals to the electronic scanning circuit. On scanning the presence of Registration Mark; it gives transistorised output.
   
   A logic controller is also provided which accepts signals from scanning head & other Proximity Sensors to keep correct pouch / bag length by driving correction motor (110V AC, 4 wire) or (230VAC, 3 wire).
