Allen-Bradley 802T R7TD Time Delay Limit Switch

The Allen-Bradley 802T R7TD Time Delay Limit Switch delivers precise delayed switching for sequencing and safety in industrial systems. It supports delayed position detection and timed actuation across conveyors, packaging lines, bottling lines, process equipment, and automated production lines requiring timed actuation. With an oil-tight heavy-duty metal housing and surface-mount design, it is built for harsh environments and carries protection ratings of NEMA 1, 3, 4, 6, and 13, operating from -20°C to +85°C. The switch features a plunger-type actuator, a 1 NO + 1 NC snap-action contact configuration, and an adjustable mechanical/pneumatic delay (model dependent) for controlled timing, along with conduit entry of 1/2" NPT. As part of the 802T Bulletin series, the device is suitable for repair, retrofit, and replacement to ensure accurate timing control in machine operations. It supports operating voltages up to 600 VAC and currents up to 10 A, making it applicable to a wide range of industrial actuation tasks in conveyors, packaging and bottling lines, machine tools, and material-handling systems. Common replacements include Allen-Bradley 802T-A and 802T-AP, and Schneider Electric XCKJ10541.
