Allen-Bradley 800T-XD2R Contact Block

Allen-Bradley 800T-XD2R is a 30 mm logic-reed contact block designed to pair with Allen-Bradley 800T push-button operators. This accessory provides a single normally closed (NC) contact to a 30 mm push-button assembly, enabling an auxiliary signaling circuit or interlock function that opens the NC path when the button is pressed, without altering the operator’s primary action. The XD2R variant is the reed-contact option in the 800T catalog and is listed as a 1NC block for 800T panels; it mounts on compatible 30 mm 800T heads and preserves the standard 800T form factor. Designed for integration with the 800T family, the XD2R stacks with other contact blocks to tailor control circuits for signaling or interlock roles in industrial panels, from simple PLC inputs to more complex safety interlocks in conveyors, presses, and packaging lines. In field wiring, it serves as a compact auxiliary contact to provide feedback or duplicated signaling paths while the main push-button operation remains unchanged.
