This Roller Lever Type device typically uses a roller lever actuator with a snap-action contact mechanism and a spring-return operating style, all housed in a Type 2 enclosure to withstand typical industrial environments. The 801 line is designed for multiple contact configurations and electrical ratings, with documented variants showing two contacts and a choice of Normally Open or Normally Closed arrangements depending on the exact model. Common applications include machine end-stop signaling on conveyors, presses, packaging lines, and other automated systems where precise end-of-travel detection is required. When selecting or replacing an 801-AS021X, verify the exact actuator, contact arrangement, and electrical ratings to ensure compatibility with your control circuits and safety requirements. The family’s flexibility—through different actuators and arrangements—helps tailor the switch to fit existing panels, mounting footprints, and wiring schemes in industrial controls.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":51657453568302,"sku":null,"price":2465.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ce2f5fc6-b213-4d61-83dd-c251bda1052a.jpg?v=1769469111","url":"https:\/\/plgautomation.com\/products\/allen-bradley-801-as021x-limit-switch","provider":"PLG Automation ","version":"1.0","type":"link"}
