Position Limit Switches
Position limit switches from Industrial Power & Control are designed to control the movement of overhead cranes, hoists and machine tools. Both the enclosure and the cover of X-FSC & X-FRZ switches are made of a thermoplastic nylon reinforced glass fiber. The 7551 Series is designed for severe operating conditions with a die-cast aluminum enclosure, resistant to impact, chemicals and corrosion. The X-FCS series has "T" or "Cross" rods that move to 3 or 4 positions, while the X-FRZ series features a single rod or a rod with roller and spring return.
