Laser sensors for displacement, distance and position


Leadership in laser distance measurements:
precise, compact & smart

optoNCDT sensors have set milestones for industrial laser displacement measurement. Whether for displacement, distance or thickness measurement, Micro-Epsilon laser sensors are considered one of the best in their class. These laser sensors are used e.g. in measurement and monitoring tasks in factory automation, electronics production, robotics and vehicle construction.

Highest precision in their class

Due to high measuring rate, laser sensors from Micro-Epsilon offer high measurement accuracy and provide reliable results even in continuous industrial operation. Most of the optoNCDT sensors can be set up using a web interface. Therefore, set up and configuration of the sensors is convenient and can be stored and transferred to other sensors via a standard web browser.

Compact design with integrated controller

optoNCDT laser sensors are extremely compact and equipped with a completely integrated controller, enabling a straightforward, rapid mounting and wiring. These laser sensors can be easily installed even in restricted spaces.

Variety of models to overcome any challenge

Micro-Epsilon laser sensors not only measure matt surfaces but also metallic and shiny targets. In addition to conventional laser models, LaserLine models (LL) with an oval-shaped laser point are also available. These sensors filter out physically induced interference and therefore significantly simplify measurements on shiny surfaces. More than 85 laser sensors with measuring ranges from 2 – 1000mm cover a large number of applications across many different industries. Equipped with intelligent interfaces and cables that are qualified for use with drag chains and robots, these laser sensors can be applied in almost any measurement task in industrial automation.

Innovative sensors with patented Blue Laser Technology

The optoNCDT BL models are equipped with a blue laser diode and are used when standard sensors with a red laser diode are operating at their performance limits. Due to its shorter wavelength, the blue laser does not penetrate the target surface, projecting a small light spot on the surface and therefore providing stable and precise results. This technology is preferably used with organic and (semi-)transparent objects, as well as for red-hot glowing metals.

Measurement tasks involving blue laser sensors on red-hot glowing objects exceeding 700 °C and transparent objects such as glass and plastics, are protected by patent law. The optoNCDT Blue Laser models achieve excellent signal stability and thus precise measurement results on these surfaces.
