Brilliant Performance with the GM04 Gloss Sensors

How can transparent adhesive tapes or labels on packaging be detected easily and reliably? The gloss sensors distinguish between matt and glossy surfaces and thus also provide reliable monitoring of paint or glue applications as well as drying conditions.

Product Highlights of Gloss Sensors

Versatile Application

  • Versatile applications in compact M design (57.3 × 27 × 16 mm)

  • Stable object detection with a working range of 5 to 40 mm 

  • Reliable performance in extreme temperature ranges from –25 to 60 °C 

  • Protection class IP67 for optimal protection from dust and water

Additional Functions via IO-Link

Versatile Applications of Gloss Sensors

Presence Check of Labels on Shiny Cans

In the packaging industry, labels are applied to cans in so-called hot glue labeling machines. To ensure a high quality standard, it is necessary to check that the labels have been correctly applied to the corresponding cans. For this purpose, a gloss sensor with laser light is installed next to the conveyor line.
