Allen-Bradley 800MR-A3AK is a small round electromechanical push-button unit from Rockwell Automation’s 800MR family, designed for 22 mm panel-mount installations in industrial control panels. The A3AK designation identifies a specific variant within the 800MR line, used as a user input to start, stop, or control machines in automation systems. This compact push-button is commonly paired with matching 800MR contact blocks to provide a reliable operator interface in harsh industrial environments. Part of the 800MR series, it offers a standardized, field-replaceable solution for panel-mounted control stations across manufacturing, packaging, and process lines.
