Allen-Bradley 802T-R8TD Time Delay Limit Switch

Allen-Bradley 802T-R8TD Time Delay Limit Switch is a standard Rockwell Automation Bulletin 802T device designed for timed-control sequences in industrial automation. This model features an off-delay timing function and a non plug-in time-delay mechanism, housed in a full head-and-body enclosure with two independent circuits. A rotary lever arm provides robust actuation and is configured for counterclockwise-only movement, and it supports standard mounting in control panels or equipment frames. The 802T-R8TD’s two circuits enable dual signaling paths, simplifying wiring in compact layouts while delivering reliable mechanical and electrical performance under industrial conditions. Typical applications include sequencing machine cycles, interlocking operations, and delayed actuation where a controlled interval between input actuation and contact change is required.
