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. Approvals UL Listed CSA Certified IEC.947.5.1 TUV -- E9271605E02 Product Features (where shown) For the most current information on this product, visit our web site at: www.sensingsolutions.com Modular, plug-in components (head, body and receptacle) provide application flexibility, reduced inventory and less downtime Manufactured to take the physical and environmental abuse (including cutting fluids and chemicals) of harsh industrial environments Chemical resistant Viton gaskets, seals and boots are standard, and so are captive, posi-drive screws The switches have terminal identification on the nameplate for a visual wiring checkout without guesswork. Heads and switch bodies can be replaced without rewiring E50 devices can be ordered in separate components or as complete assembled switches 600V rating, ridge-topped contacts and wiping action assure continuity even to logic level circuits Keyed, four direction head positioning Standard 5 pre-travel and 90 total travel 24 - 120V AC/DC LED and 120V AC neon indicating lights available Rotary heads are field convertible CW, CCW, or both, without special tools Epoxy filled, pin connector or pigtail pin connector receptacles available For Customer Service in the U.S. call 1-800-356-1243, in Canada call 1-800-268-3578.
