Banner Engineering LH Laser Displacement Sensors

The LH series of precision laser displacement sensors were developed to add a high performance sensor to Banner Engineering’s triangulation displacement product offering. The LH series is a high speed, high precision, non-contact measurement sensor which provides accurate and stable displacement or thickness measurement on wood, metal, rubber, ceramic, and plastic parts.

The LH series of sensors incorporate a linear camera to overcome the application effects of color and surface texture experienced on position sensitive device (PSD) sensors such as the Banner LG5 and LG10.


  • Extremely accurate, robust and self-contained laser displacement using a 1024 pixel CMOS linear imager
  • Precise narrow laser spot for easy alignment to the target
  • Reliable and accurate measurement results on real world targets, such as machined metal, wood, ceramic, paper and painted targets
  • Target displacement or target thickness measurement with high resolution 4-20 mA or RS-485 serial communication outputs
  • Non-contact measurement for use on moving processes, hot parts, machined parts, and soft or sticky parts
  • Two sensors self-synchronize for thickness measurements and thickness calculation within the sensors; no external controller required
