Allen-Bradley 800MR-D6A Round Push Button Unit

The Allen-Bradley 800MR-D6A Round Push Button Unit is a red 22 mm round operator designed for momentary actuation in control panels. As part of the Allen-Bradley 800MR family from Rockwell Automation, it provides a compact, robust input for basic start/stop and signaling tasks in industrial automation. The D6A variant identifies this round operator within the 800MR lineup and is intended to be used with compatible contact blocks and mounting hardware to create a complete push-button assembly. This unit is designed for 22 mm panel installations, enabling straightforward replacement alongside other 800MR components to preserve a consistent control-station appearance and behavior. The momentary action means the contact returns to its resting state when released, making it suitable for momentary control signals and interlock-type functions in machine-control circuits. Red is a conventional color choice for action points that require immediate operator attention in an automation scheme, aiding quick recognition on crowded panels.
