Allen-Bradley 802T-ATH Limit Switch

The Allen-Bradley 802T-ATH Limit Switch delivers precise, repeatable position sensing and end-of-travel control in industrial automation, with an oil-tight heavy-duty metal housing designed for conveyor systems, packaging lines, and material handling processes. It uses an adjustable lever actuator (typical configuration) and features a 1 NO + 1 NC snap-action contact arrangement, with ratings up to 600 VAC and up to 10 A. The enclosure carries NEMA Type 1, 3, 4, 6, 13 protection, is designed for surface mounting, and accepts 1/2" NPT conduit entry, operating from -20°C to +85°C. Common replacements include Allen-Bradley 802T-AT and 802T-AP, and the switch is applied in conveyors for object detection, packaging and bottling lines for sequence control, machine tools for limit positioning, and material handling systems to prevent overtravel and protect equipment.
