BW Controls 1500-D-L4-S7 Limit Switch Assembly is a mechanical limit-switch module designed for BW Controls’ 1500-series control systems, delivering end-of-travel signaling in industrial automation. The model code places it in the 1500-D family with an L4 configuration and S7 contact arrangement, providing a robust interface for detecting machine position and triggering downstream controls. Typical applications include interlocks, safety shutoffs, and position sensing in pumps, valves, conveyors, and other motion-driven equipment where reliable limit sensing is essential.
