E50

E50 Modular Plug-In Limit Switchcomponents are the industry standard withversatility of design and high reliability forlow maintenance, installation and inventorycosts. Standard FKM gaskets, seals andboots, and a zinc die cast enclosure provideexceptional chemical resistance to thecommon coolants, cleansing agents, andhydraulic fluids found in machine tool,automotive, waste water treatment and otherheavy-duty industrial applications. Mountingdimensions accommodate both U.S. andDIN standards for easy retrofit installations.Super bright 24 to 120 Vac/dc LEDindicating light versions simplify setup andtroubleshooting operations.
