Allen-Bradley 802T-NPTP Limit Switch

Allen-Bradley 802T-NPTP is a metal, plug-in oil-tight limit switch in Rockwell Automation’s 802T family, engineered for rugged end-of-travel sensing on industrial equipment. The NPTP variant provides a 1/2" NPT conduit-entry thread and a four‑circuit contact block with two normally open and two normally closed contacts for flexible signaling and interlock logic. It uses a rotary lever arm option and supports actuation in clockwise or counterclockwise directions with a neutral position, all within a head-and-body assembly designed for standard NEMA-style mounting in plug-in configurations. Built for harsh environments, it is oil-tight with a metal housing and intended to be paired with a compatible base for quick field replacement. Typical 802T configurations offer a 10 A rating for standard loads, and the temperature range encompasses low-temperature operation down to -18 °C and high-temperature operation up to about 110 °C, making it suitable for cold rooms and hot production floors. In practice, the 802T-NPTP supports end-stop, gate, and safety-interlock applications on conveyors, presses, and other machinery where robust position sensing in challenging conditions is required.
