Allen-Bradley 802T-NPTP1 Oil Tight Limit Switch

Allen-Bradley 802T-NPTP1 is a four‑circuit, plug‑in oil‑tight limit switch in a head‑only configuration designed for demanding industrial environments. It features NEMA 4 and 13 oil‑tight construction to resist dust, water, and lubricants, making it suitable for conveyors, packaging lines, and washdown areas. The unit uses a lever‑type actuator with spring‑return and a neutral-position arrangement for repeatable actuation and defined rest. The four circuits provide two normally open and two normally closed contacts, enabling multiple signaling and interlock arrangements in a single device. As a plug‑in 802T family member, it supports quick field installation with compatible plug‑in bases and standard mounting practice. The rugged metal housing and gasketed seals support long service life in harsh plant environments while maintaining reliable operation in oil‑exposed equipment. This model is commonly employed for safety interlocks, limit sensing on automated machinery, and process lines where dependable, easy replacement of a worn switch is prioritized.
