NAMCO Controls Snap-Lock Limit Switch EA040-11100

The NAMCO Controls Snap-Lock Limit Switch EA040-11100 is a robust, heavy-duty industrial switch designed for precise position detection and control in demanding environments. Manufactured by NAMCO Controls (now part of Sensata Technologies), this rotary-actuated limit switch features a die-cast aluminum enclosure for durability and resistance to harsh conditions, including dust, moisture, and mechanical stress. It is commonly used in applications such as conveyor systems, machine tools, elevators, and material handling equipment to signal limits of motion, ensuring safety and operational efficiency. Key features include a snap-lock mechanism for quick installation and maintenance, high electrical ratings for reliable performance, and NEMA 4 enclosure rating for environmental protection. Advantages over similar products include superior longevity in industrial settings, easy adjustability via the rotary shaft, and compatibility with various control systems. However, it may require periodic lubrication for optimal performance in high-vibration areas. Based on attached images, this unit appears used with visible wear, faded labels (e.g., ampere rating partially illegible), and no apparent damage; faceplate shows CAT. NO. EA040-11100, with a mounting bracket and red grommet at the base. No parent/child assets are visible.
