E50 Heavy-Duty Modular Limit Switches

The E50 Modular Plug-In Limit Switch from Eaton's Cutler-Hammer sensor business are the industry standard with versatility of design and high reliability for low maintenance, installation and inventory costs. Standard Viton gaskets, seals and boots and a zinc die cast enclosure provide exceptional chemical resistance to the common coolants, cleansing agents, and hydraulic fluids found in machine tool, automotive, waste water treatment and other heavy-duty industrial applications. Mounting dimensions accommodate both U.S. and DIN standards for easy retrofit installations. Super bright 24 - 120V AC/DC LED indicating light versions simplify setup and troubleshooting operations.
