Compact machine designs with limited space, detection of very small objects, narrow gaps, or precise triggering - and at fast clock rates. These are just some of the application areas for the new optical O200 miniature sensors with focused laser light beam. The new laser variants now enable even higher precision in the detection of very small position differences, extremely narrow gaps, as well as small parts such as single wires or very fine threads with a diameter of only 0.05 mm.
