The LD46 luminescence sensors emit ultraviolet light and detect only visible light converted and reflected from fluorescent objects or marks, independent from the background color and surface. The LD46 sensors can reach a 100mm operating distance and a 2kHz switching frequency, thanks to the UV high-power emission using 6 LEDs. The high power and definition of the LD46 sensor light spot enable the detection of critical targets with a very poor or non-homogeneous or discontinued luminescent level, as for example on raw wood, corrugated carton, fabric, ceramic tiles.

Features & Benefits

  • UV power emission: high detection reliability
  • Teach-in push-button and bar graph indicator: fast and easy setting
  • 2 KHz switching frequency: precise and repeatability reading
  • Rotatable M12 5-pole connector: adaptability to the mechanical part of the plant
