L-GAGE LG5 and LG10 Series

Overview

  • Conserves production space by using a one-piece design
  • Does not touch parts it measures, so can be used with moving processes, hot parts and sticky parts
  • Provides 12 to 30V dc supply voltage with either an NPN or PNP discrete output, and a 4-20 mA or 0-10V dc analog output
  • Automatically scales the analog output over the width of the programmed sensing window
  • Features outstanding maximum resolution of 3 µm for flat white targets
  • Uses an ultra-narrow beam to precisely measure distance, height or thickness
  • Available in ranges of 45 to 60 mm (LG5) and 75 to 125 mm (LG10)
  • Lets you pick the exact range you need with the push of a button
  • Features push-button TEACH-mode programming for custom sensing windows
  • Offers remote programming for added security and convenience
  • Uses push-button programming for three output response speeds
