When displacement and distance must be determined over long distances with high accuracy, optoNCDT ILR2250 laser distance sensors provide reliable results. The sensors can be mounted both indoors and outdoors. For outdoor measurement tasks, laser distance sensors are available with integrated heating and cooling. This allows the sensors to be operated at temperatures from -40 °C to +65 °C. In addition, the aluminum die-cast housing is very robust.
The measurement results are stable and precise at long distances of up to 150 m. This also applies to dark, structured or weakly reflective surfaces. Different measurement modes allow adaptation to the respective measurement task.
The laser distance sensor is impressive with its high speed capability and is, among other things, used in logistics and automation technology, the metals industry and production monitoring.
