Allen-Bradley 802XR-A4F7 Limit Switch

Allen-Bradley 802XR-A4F7 is a sealed hazard-location limit switch from Rockwell Automation designed to provide reliable position sensing in harsh industrial environments where dust, water splash, or explosive atmospheres may be present. It features a lever-type actuator and sealed contacts with a normally open (N.O.) output configuration, built to satisfy hazardous-location protection for NEMA 7 and NEMA 9 installations. As part of the 802XR family, this switch is engineered for rugged operation within safety-critical control systems, aligning with Rockwell’s limit-switch specifications and installation guidelines that describe lever-actuated heads and sealed-contact performance in hazardous settings. Typical applications include end-of-travel sensing and safety interlocks on conveyors, processing lines, presses, and other machinery in industries such as oil and gas, chemical processing, mining, and related sectors where certified devices are required to meet stringent safety and environmental standards.
