Sensor solutions for this application

9547-3-DCH_16-9-bg_hybris_teaser.png

Product infeed via object slider with diffuse sensors with background suppression

  • The V-shaped, very narrow LED light beam enables detecting challenging objects ranging from transparent to jet black objects.
  • Response time of 250 µs supports short cycle times of the machine.
  • Miniature housing enables installation in small spaces.
  • High-precision object handling guarantees a stable and accurate labeling process.
  • Reduction of sensor variants, as the sensor is suitable for other applications in the machine.

Product infeed with laser diffuse sensors with background suppression

  • Laser sensors with an extremely small spot and very short response times guarantee accurate edge detection in highly dynamic labeling processes. 
  • High-precision triggering during acceleration, deceleration, stopping and restarting in combination with the high resolution encoder.

Programmable encoder for speed-independent triggering

  • High resolution of the incremental encoder ensures speed-independent positioning of the objects.
  • The wide range of configuration options ensures maximum availability and flexibility and reduces the variant diversity.
  • Low space requirement on conveyor belts due to compact 38 mm installation depth.
