Precision Limit Switches


Limit switches are popular for presence sensing in industrial controls. Metrol miniature limit switches offer incredible precision with repeatability down to 0.5 microns. With a service life of three million cycles, these precision switches are perfect for robotic and machine tool applications. Their small sizes (down to 4mm or M5 barrel) accommodate very tight mounting spaces.
