Allen-Bradley 800H-R1D2 Momentary Push Button

Allen-Bradley 800H-R1D2 is a 30 mm diameter momentary push-button operator with a booted head, finished in green, from the 800H family of industrial control hardware. It provides two normally closed (NC) standard contacts, allowing designers to implement short-duration input signals in control circuits when the button is pressed and to revert when released, depending on the wiring arrangement. The booted head protects the wiring terminals and contact block from dust, debris, and incidental contact, while the compact 30 mm footprint fits common mounting cutouts and aligns with other 800H operators in a modular panel layout. This durable operator is typically used in machine controls and process automation for functions such as resets, jog commands, or momentary start signals, with the green color serving as a visual cue within a panel’s color-coding scheme to help operators identify the function quickly. Compatible with standard 800H mounting configurations and contact blocks, the 800H-R1D2 can be paired with appropriate accessories to tailor a compact, reliable input solution for demanding industrial environments.
