SENSOR SPECTRO represents a state-of-the-art NIR sensor sorter that integrates an induction bar and a near-infrared (NIR) system to precisely separate input materials based on their electrical conductivity and molecular oscillations. For additional detection of colour and shape, this sorter is also available with an optional colour camera system.

This sorter combines the advantages of conductivity detection using an induction bar with the detection of molecular compounds using the near-infrared (NIR) camera. Optionally, a colour camera enables the detection of colour and shape for precise sorting. The sensor sorter ensures high accuracy when sorting different plastics according to types and colours. Detected particles are sorted out using compressed air to ensure precise separation.


  • Conductivity-based detection and detection of molecular oscillation
  • Suitable for input materials from 10 – 100 mm
  • Integrated compressed air treatment available
  • Robust & low-maintenance

Suitable for the following applications:

BLUELINE is a dynamically reconfigurable processing system with a modular design.
