Allen-Bradley 800F-1YM2HD Emergency Stop Switch

The Allen-Bradley 800F-1YM2HD Emergency Stop Switch is a 22 mm emergency stop operator housed in a red enclosed half-dome head and mounted in a 1-hole plastic enclosure for panel installations. This non-illuminated E-stop station features a single normally open contact configuration, making it suitable for auxiliary signaling or safety-circuit wiring within a broader machine-safety architecture. The compact 22 mm footprint fits standard 22 mm push-button cutouts, while the bright red half-dome head provides immediate visual recognition and tactile feedback for rapid actuation in emergencies. As part of the 800F family, it is intended to serve as a dedicated emergency-stop input within control-panel safety schemes, enabling clear operator interaction and reliable signaling to safety relays or controllers when integrated with the system’s safety logic. The HD designation confirms the red half-dome lens/head option, and the 1-hole enclosure denotes a panel-mount assembly engineered for industrial environments where a compact, robust stop control is required. This model is ideal for applications needing a clearly labeled, non-illuminated emergency stop with a single NO contact to complement other safety devices and interlocks.
