Allen-Bradley 800H-R2A Servo Drive

Allen-Bradley 800H-R2A is a 30.5 mm green, momentary pushbutton operator from Rockwell Automation’s 800H family. It provides a two-contact configuration: 1 normally open and 1 normally closed, enabling basic start/stop or interlock signaling from a single actuator. Designed for panel-mount installation, it works with standard 800H mounting hardware and is commonly used in industrial automation to capture operator input in machines, conveyors, and packaging lines. As part of the 800H pushbutton range, the R2A variant combines a compact external footprint with color-coded actuation to help operators quickly identify functions in control stations, while permitting straightforward wiring of two discrete contacts for simple control circuits.
