LTF Series Laser Measurement Sensors

Overview

High-performance LTF Series Sensors detect targets regardless of color, material or sheen from up to 12 m away, straight-on or at an angle.

  • Analog and Discrete outputs for measuring and detection applications
  • Best in class combination of range, repeatability and accuracy enable highly reliable target detection and precise distance measurement
  • Two-line, eight-character display and pushbutton programming for easy setup, troubleshooting and real-time distance measuring
  • Durable IP67 housing, high ambient light immunity and stable performance across temperatures provide reliable performance in challenging environments
  • Advanced options, including delay timers, advanced triggered measurement modes and cross-talk avoidance
