Eaton E51DP3 - The E51 Limit Switch Style Modular Sensors present a versatile solution for various sensing applications, with options including thru-beam, reflex, polarized reflex, diffuse reflective, and fiber optic modes. These modular sensors are easy to maintain and come in both two-wire (AC/DC operation) and four-wire (AC or DC) configurations, offering flexibility. They can be ordered as components or fully assembled units. Notable features include a selector switch for light or dark operation, optional logic modules for added control functions, rugged construction suitable for industrial environments, and Viton gaskets for a secure seal and chemical resistance. The sensors can be rotated to four positions, and their components are interchangeable with E51 proximity sensors. They also accommodate both U.S. and DIN mounting dimensions and ensure a reliable electrical connection with bifurcated engagement prongs. These sensors are a robust and adaptable choice for a wide range of sensing needs. -
