It provides the mechanical interface between a moving machine component and the limit switch actuator, translating physical contact into an electrical signal. The roller body is cast zinc construction and measures 1.5 inches in overall length with a 0.25-inch diameter. The rolling element itself is steel, offering durability in repetitive-contact applications. This part is installed by licensed electricians and industrial maintenance technicians working on machinery, conveyor systems, and automated equipment where position sensing is required.\u003c\/p\u003e\n\u003cp\u003eThe 7XA1 lever roller is suited for use in light industrial and commercial settings where limit switches require a replacement or substitute roller assembly. Typical applications include conveyor end-of-travel detection, door and gate position sensing, and machine guarding circuits. The 0.25-inch face width steel roller is built to handle the mechanical wear associated with frequent actuation cycles. This component is most commonly installed during scheduled maintenance or after mechanical damage to the original roller assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCast zinc body construction for corrosion resistance in light industrial environments\u003c\/li\u003e\n  \u003cli\u003eSteel roller element rated for repetitive-contact actuation cycles\u003c\/li\u003e\n  \u003cli\u003e1.5-inch overall length fits standard limit switch lever arm configurations\u003c\/li\u003e\n  \u003cli\u003e0.25-inch roller diameter with 0.25-inch face width for precise contact engagement\u003c\/li\u003e\n  \u003cli\u003eSingle-piece accessory sold individually, no additional hardware bundle required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement lever roller accessory for use with compatible limit switches.

De-energize and lock out the machine circuit per OSHA lockout\/tagout procedures before removing the existing roller or accessing the limit switch assembly. Verify that the replacement roller pin diameter and face width are compatible with the existing lever arm before assembly. Do not operate the limit switch beyond its rated mechanical actuation force after roller replacement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.6 inches L x 1.3 inches W x 0.5 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7XA1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51539367493938,"sku":"7XA1","price":49.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7786f5144ba35e65b563d3709e43f113.jpg?v=1785838857","url":"https:\/\/voomisupply.com\/products\/square-d-7xa1-limit-switch-lever-roller-cast-zinc","provider":"Voomi Supply","version":"1.0","type":"link"}
