Micro-Epsilon also offers the optoNCDT 1420 laser triangulation sensors with laser class 1. With this laser class, the maximum emitted power is 390 µW, which means that the protective measures associated with laser class 2 do not apply. The laser triangulation sensors measure displacement and distance without contact and detect even the smallest objects thanks to their tiny measuring spot diameter. Particularly in automotive production, manufacturers place increased demands on the safety of their production systems and therefore require the use of sensors with laser class 1. This is the case, for example, when handling devices are used to attach or install interior parts and laser sensors are used for alignment. Under unfavorable circumstances, the worker may look directly into the laser beam or the reflections of the beam. With higher laser classes, the beam can cause irreparable damage to the retina of the person affected. Laser class 1 is also frequently required in the pharmaceutical industry. In some applications, laser sensors are used to determine distances to sensitive surfaces or to measure substrates. Under certain circumstances, class 2 lasers can cause a chemical or thermal reaction on the surface. In these areas, sensors with laser class 1 are used, as the low laser power does not cause a chemical or thermal reaction.
