LDu Series

Key Features

  • High-Power UV LED emission
  • Microprocessor-based Teach-in setting
  • High switching frequency at 2 kHz
  • Fiber optic accessories and high-resolution lenses


The LDμ luminescence sensors emit ultraviolet light and detect only visible light converted and reflected from fluorescent objects or marks, independent from the background’s color and surface. A microprocessor controls and synchronizes the emission, reception and output circuits offering a completely automatic setting. The LDμ sensors can reach a 75 mm operating distance and a 2 kHz switching frequency, thanks to the UV High-Power emission. Focusing lenses and special fiber-optics able to replace the lens are available as accessories.

The LDμ sensors are used in the pharmaceutical and cosmetic industries to identify labels on glass phials or bottles; in the wood and ceramic selection lines; in automatic packaging to detect paper and fluorescent glues; in the textile industry to identify cutting guides; in the mechanical industry to verify the presence of paints or fluorescent lubricants.
