Customizable Sensitivity: The hole dimension required to trigger the device (threshold) is easily adjustable via a two-decade selector and can be confirmed with test microholes.

Verification Instruments: Upon request, a dedicated kit with three reference gauges (hole diameters of 0.035 mm, 0.050 mm, and 0.100 mm) can be supplied for regular calibration checks of the receiver (threshold adjustment).

Technical Information

Device Composition

This system is composed of two distinct modules:

Illuminator

  • Installed above the film conveyor line.
  • Emits a powerful infrared light beam, which is directed onto the film using a cylindrical lens.
  • Lateral supports guarantee optimal alignment.
  • Functions autonomously and is equipped with a relay output to signal any lighting circuit malfunction.

Receiver

  • Mounted below the path of the film.
  • Features a sequence of photosensitive elements arranged along the axis that matches the film’s width.
  • When the light from the upper illuminator passes through a flaw, the internal electronics issue an alert to identify the presence of a hole or crack.
  • Requires precise alignment with the illuminator and complete shielding from external light sources.
  • For embossed films, the machine’s supplier must provide a dedicated guide that closely supports the underside of the film.
