LE Series Laser Measurement Sensor

Overview

The LE series' linear array technology provides great performance and resolution regardless of detection object's color or sheen.

  • Ready to measure right out of the box
  • Easy adjustment with a two-line, eight-character intuitive display
  • Linear array provides repeatability and accuracy for challenging targets
  • Visible laser for small spot size and easy alignment
