This 800H component provides a straightforward push-button interface for local control tasks and is intended to be used with compatible 800H panels or enclosures that accept 30 mm modular pushbuttons. The WK42B designation identifies a specific variant within the 800H 30 mm pushbutton lineup, part of a modular, field‑replaceable interface known for mechanical durability in harsh industrial environments. Common applications include machine start\/stop circuits, process control stations, and control panels in manufacturing lines where reliable, quick‑replaceable pushbutton devices are required. The 800H family is designed for interchangeability with other 30 mm pushbuttons, enabling designers to standardize operator interfaces across multiple machines without changing panel layouts, and these components are typically sourced through Rockwell Automation and authorized distributors to ensure compatibility with Rockwell software and control ecosystems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657517662510,"sku":null,"price":109.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f8729ae6-99e9-4f37-bc79-67f402a61e65.jpg?v=1769469783","url":"https:\/\/plgautomation.com\/products\/allen-bradley-800h-wk42b-hmi-panelview-operator-interface","provider":"PLG Automation ","version":"1.0","type":"link"}
