Field of application:

  • Materials with dust or fluff-like deposits
  • Films with a variable level of transparency
  • Light-sensitive materials

Optical sensors (IR)

Non-contact scanning of the web edge is carried out by light.

Field of application:

  • Transparent and non-transparent materials
  • Thick materials

Contrast sensors

The non-contact scanning of the web material is carried out by detecting optical contrasts.

Field of application:

  • Digital scanning of web edges, printed edges or printed lines
