AutomationDirect has added more high precision limit switches from Metrol. New High-temperature precision limit switches provide a 10 micron accuracy and are rated for temperatures of up to 200°C. Also new are high-vacuum resistance limit switches with an accuracy of 10 microns designed to be used in a 10-5PA high-vacuum environment. High-vacuum resistance precision limit switches come in stroke lengths from 0.8 to 5mm and are available in M5x0.5, M14x1 and 16x1 mm threaded barrel diameters. Metrol high temperature and high vacuum resistance precision limit switches have a 1-year warranty.
