Datalogic - LD46 - Luminesence sensors

  • 6 x High-Power UV LED's
  • Teach in push botton setting
  • Simple setting with +/- buttons
  • Rotatable 5-pole M12 connector
  • PNP/NPN output

Product description

The LD46 series with luminescence photoelectric sensors transmits UV light and detects solely visually converted light that is reflected from a fluorescent surface, independent of background colour and surface. The photoelectric sensors work with 6 x High-Power UV LED's that enable detection on surfaces with unevenly fluorescent material.

The sensors are used within the wood industry where the surfaces can be uneven, the pharmaceutical and cosmetics industry to detect labels on test tubes and glass bottles. In packaging machines to detect paper and fluorescent adhesives and within the mechanical industry for detection of fluorescent lubricants and thread locking.
