The D9A designation identifies a mushroom head (D) with a yellow actuator (9) and a 1 NO–1 NC contact arrangement (A), providing one normally open and one normally closed path for actuation. The round operator is paired with a grey bezel and uses the standard 22 mm mounting footprint common to the 800MR family, and the unit is non-illuminated, intended for simple start\/stop and reset-type control signals in PLC- or relay-based circuits. Momentary action means the contacts return to the open state when the button is released, enabling short, pulse-like inputs in automation sequences. This configuration supports wiring in straightforward control circuits where a single push-button input triggers a defined action through both an NO and NC path.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657512550702,"sku":null,"price":90.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_9ba308a2-4631-475e-bb4b-178451bc472d.jpg?v=1769469729","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800mr-d9a-momentary-push-button","provider":"PLG Automation ","version":"1.0","type":"link"}
