A look at practical sensor applications

Extremely versatile application potential of optical sensors for object detection:

  • Presence check of objects in processes independent of the specific object position
  • Extremely fast and precise position detection, even of the smallest objects
  • Detection of objects also across large distances
  • Reliable count of objects, also with the smallest distances
  • Recognition of different object materials, colors, and contrasts
  • Object detection, even with transparent, uneven, punctured, or rough surfaces
  • Detection of objects through the smallest openings
