Schneider Electric NSB 9007B052F Limit Switch

Schneider Electric NSB 9007B052F is a rotary head limit switch component in the Square D NSB/9007 family, built to mount on compatible 9007C bodies and deliver a CW actuation without a lever arm. This plug-in head (9007B series) is specified for standard pretravel spring‑return operation and translates rotary motion into an electrical change via snap‑action contacts when actuated, making it well suited for position sensing, safety interlocks, and travel‑limit sensing in industrial equipment. By design, the NSB 9007B head supports compatibility with common 9007C contact blocks and mounting accessories, while lever arms and adapters are typically sold separately to tailor actuation feel and travel distance to conveyors, doors, presses, and packaging lines. The product is listed as a single unit sold EA, allowing you to source exact head replacements without replacing the entire switch assembly. As part of Schneider Electric’s Square D line, the NSB 9007B052F emphasizes modularity and easy field replacement, enabling quick maintenance in demanding industrial environments.
