Precision limit switches
AutomationDirect has added a line of high precision limit/position switches from Metrol. These cost-effective, ultra-precise mechanical limit switches have repeatability down to 10, 5, 3, and 0.5 microns (µm) depending on the specific model. These stainless steel limit switches’ tiny size allows them to be mounted in tight locations. With a 4mm diameter barrel and length of 12.8mm, model BP4SWA is the smallest precision limit switch on the market. They are also available in 5mm and 6mm smooth barrel, and M5, M6, M8, & M10 threaded barrels. 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.
