Allen-Bradley 802T-R3TD Oil Tight Limit Switch

Allen-Bradley 802T-R3TD is a two-circuit, oil-tight plug-in standard limit switch from Rockwell Automation with a pneumatic time-delay mechanism and a rotary lever actuator. Housed in a NEMA Type 13 enclosure, it is designed for environments where oil, dust, and washdown conditions are present. Each circuit provides 1 normally open and 1 normally closed contact (1NO-1NC), enabling simple control logic for end-of-travel sensing and safety interlock duties. The 802T family is used to detect machine travel limits and to trigger downstream control in automation systems, including conveyors and packaging lines, where reliable actuation under oily conditions is required. The combination of oil-tight sealing, plug-in mounting, and a lever-operated time-delay makes it well-suited for applications that demand delayed response to prevent chatter and false trips in rugged industrial environments.
