Allen-Bradley 800F-1YM3 Pushbutton Emergency Stop

Allen-Bradley 800F-1YM3 is an assembled emergency-stop (E-stop) station designed for panel mounting in industrial equipment. The unit features a yellow plastic enclosure with a 1-hole mounting footprint and houses a 40mm twist-to-release emergency stop operator, which is non-illuminated. It provides two normally closed (2 NC) contacts, enabling dual-channel stop circuits or interlock wiring within a control system. This 800F station is part of Rockwell Automation’s 800F pushbutton family, built to withstand the rigors of harsh factory environments while delivering a clear, decisive stop action. The 1YM3 designation identifies the enclosure and mounting configuration, making it a direct replacement or upgrade for compatible 800F installations. Typical applications include stopping machinery on conveyors, presses, packaging lines, and other automated equipment where a rapid immediate stop is required. When wiring, connect the two NC contacts in the safety circuit to interrupt control power to the hazardous function, and use the twist-to-release mechanism to reset the button after actuation. This configuration provides a compact, maintenance-friendly safety stop station that coordinates with Allen-Bradley 800F components for consistent performance in panel-mounted safety circuits.
