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
