Bulletin 802T
The Allen-Bradley Bulletin 802T is a family of heavy-duty, metal-bodied standard limit switches designed for industrial machine guarding, position detection, and mechanical interlock applications. The 802T prefix designates a metal Type 4/13 enclosure rated for both indoor and outdoor use, distinguishing it from the plastic-bodied 800H variants. Understanding the catalog-number structure is essential when selecting a part: the head/device-type characters encode the actuator style (roller lever, wobble, plunger, and others); the contact block code specifies the switching configuration, with common options including D2 (1 N.C.), A (1 N.O.–1 N.C.), A4 (2 N.C.), and G1 (2 N.O.–2 N.C.), while suffixes such as V indicate PenTUFF low-voltage contacts and F denotes Class I Division 2 explosion-protected versions. Frequently stocked variants include the 802T-ATE, 802T-CT, 802T-BD, and 802T-KU, each differing in actuator head style and contact arrangement. With 356 catalog numbers in this family, buyers should consult the Bulletin 802T Technical Data (800-TD009) to confirm actuator type, contact rating, and enclosure requirements before ordering.
