Robust laser distance sensors for outdoor use

Robuster Laser-Distanzsensor für Außeneinsatz

The optoNCDT ILR1171-125 laser distance sensor is designed for outdoor use. It measures 20x faster than its predecessor. Due to the laser time-of-flight principle with infrared light and a measuring rate of up to 40 kHz, high energy pulses are achieved, allowing stable measurements with very good signal quality. Even in poor visibility conditions such as fog and rain, the sensor offers high accuracy. The resistance to ambient light is 50,000 lux.

A robust IP67 aluminum housing protects the sensor, which also delivers reliable results in a temperature range of -40 to +60 °C. Due to its extremely compact design, the sensor can be installed even when space is at a premium.

Fields of application include distance measurements for structural monitoring, cranes and wind turbines. The measuring range is 125 m, an extension to 270 m is possible by means of a reflector.


  • Measuring range without reflector 125 m
  • Measuring range with reflector 270 m
  • Linearity < ±60 mm
  • High measuring rate of 40 kHz
  • Robust industrial design with protection class IP67
  • Measurement on static and dynamic targets
