Traditional limit switches are limited in terms of accuracy and repeatability. These cost-effective, ultra-precise mechanical limit switches from Metrol® have repeatability down to 10, 5, 3, and even 0.5 microns (µm) depending on the specific model. Along with their high precision, these stainless steel limit switches are also some of the smallest switches/sensors available. Their tiny size allows them to be mounted in extremely tight locations. Five precision limit switch series are available: precision touch with 3 micron or 5 micron accuracy; high precision touch and tool setter with 0.5 micron accuracy; ball plunger with 10 micron accuracy, and high temperature rated with 10 micron accuracy and operating temperatures up to 200°C. The switches are IEC IP40 to IP67 rated depending on model. Precision limit switches start at $39.50 and have a 1-year warranty.
