Square D B054B2 Limit Switch

Square D B054B2 limit switch is a heavy‑duty plug‑in limit switch in the 9007 family, designed for end‑of‑travel sensing in industrial equipment. It delivers a SPDT contact arrangement (one normally open, one normally closed), enabling simple feedback for safety interlocks and control logic. Typical ratings place it at 600 VAC and up to 10 A, making it suitable for control circuits and protection interlocks on conveyors, presses, forming equipment, and other automation lines. The unit’s rugged die‑cast zinc alloy housing provides durability in harsh environments, and it is UL, CSA, and CE listed. For installation, the switch uses a standard plug‑in mounting with 1/2 inch NPT conduit entries, supporting quick field replacement and integration into control panels. Depending on the exact configuration, related 9007 models in the same family cover a range of enclosures (NEMA 4/12/13), weather‑resistant sealing, and arm/head options to match actuation needs. This B054B2 variant is intended for reliable end‑of‑stroke signaling where compact form factor and robust construction are required in industrial machinery.
