Allen-Bradley 800M-XAR USNT is a 22 mm contact block accessory designed for use with the 800M family pushbuttons. It provides a 1 normally open (NO) and 1 normally closed (NC) contact arrangement, configured with a logic reed interface and quick-connect terminals for straightforward wiring. This block mounts to 22.5 mm pushbutton assemblies and was discontinued by Rockwell Automation on June 5, 2024, making it a legacy option for existing control stations.
