Allen-Bradley 802T-AP Timer Relay

Allen-Bradley 802T-AP is a metal plug-in oil-tight limit switch from Rockwell Automation that provides a 1NO/1NC contact arrangement for end-of-travel sensing in industrial equipment. Its rugged metal enclosure delivers dust- and water-resistance, is typically specified with an IP67 rating, and its plug-in design enables rapid actuator changes and field maintenance without the need to rewire controls. As part of the 802T family, the 802T-AP is designed for machine guarding, conveyors, packaging lines, and other automation applications where reliable travel-limit signaling to a control system is required. This configuration supports both normally open and normally closed contact paths, enabling straightforward wiring schemes for stop/start logic and interlocking in harsh manufacturing environments, and is commonly used to ensure proper sequencing and prevent damage when a moving part reaches its limit.
