The lever arm adjusts from 1.38 to 3.38 inches in length, allowing precise actuation point positioning without replacing the entire actuator assembly. The body is cast zinc for durability in industrial environments, and the roller is nylon construction with a 1\/4 inch face width and 1\/4 inch diameter. Electricians and automation technicians install this lever when replacing a worn actuator or when repositioning the actuation point on an existing limit switch installation.\u003c\/p\u003e\n\u003cp\u003eThe 7DN is suited for use with compatible limit switches in manufacturing, conveyor, and machine control applications where a mechanically operated limit switch requires an adjustable roller lever actuator. The adjustable arm length makes it practical for installations where the triggering cam or dog has a fixed position that does not align with a fixed-length lever. It is appropriate for both new installations and field replacement of damaged or worn roller levers on existing limit switch bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable arm length from 1.38 to 3.38 inches for flexible actuation point positioning\u003c\/li\u003e\n  \u003cli\u003eCast zinc body for durability in industrial service environments\u003c\/li\u003e\n  \u003cli\u003eNylon roller with 1\/4 inch face width and 1\/4 inch diameter\u003c\/li\u003e\n  \u003cli\u003eDesigned as a replacement or upgrade actuator for compatible limit switches\u003c\/li\u003e\n  \u003cli\u003eSold individually, quantity of one per package\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with limit switches as a replacement or accessory roller lever actuator. No specific compatible model numbers were provided in the product data.

De-energize and lock out the circuit controlling the limit switch before removing or installing any actuator components, following NFPA 70E lockout\/tagout procedures. Confirm the replacement lever mounts securely to the limit switch body and that the roller aligns correctly with the actuating cam or dog before restoring power. Do not force the lever arm adjustment beyond its stated range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArm Length Range\u003c\/strong\u003e: 1.38 to 3.38 inches (adjustable)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRoller Face 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: Nylon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.3 inches long, 0.6 inches wide, 0.3 inches tall\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 7DN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542316876082,"sku":"7DN","price":52.39,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6227aee41bca746cf66a688edc175f84.jpg?v=1785897942","url":"https:\/\/voomisupply.com\/products\/square-d-7dn-adjustable-roller-lever-limit-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
