Built from Alnico 5 material, it delivers a maximum pull force of 1.5 pounds (0.7 kg) from a compact 0.5-inch diameter form factor. The magnet measures 0.375 inches high with an 11\/64-inch center hole and a 9\/32-inch gap width, making it well suited for mounting in fixtures, jigs, sensors, and custom assemblies. Licensed electricians, instrumentation techs, and mechanical tradespeople commonly specify Alnico button magnets where stable magnetic output across a wide temperature range is required.\u003c\/p\u003e\n\u003cp\u003eThe E821 fits applications where a small, permanently magnetized component must retain consistent field strength under elevated temperatures. Grade 5 Alnico material maintains magnetic properties up to 550 degrees C, making it appropriate for high-heat industrial environments such as furnace sensor assemblies, motor components, and instrumentation fixtures. It is sold and packaged as a single unit, suitable for prototyping, replacement, or low-volume production work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMaximum pull force of 1.5 lb (0.7 kg) from a 0.5-inch diameter body\u003c\/li\u003e\n  \u003cli\u003eGrade 5 Alnico (Alnico 5) construction for stable, permanent magnetism\u003c\/li\u003e\n  \u003cli\u003eMaximum operating temperature of 550 degrees C\u003c\/li\u003e\n  \u003cli\u003eCenter mounting hole at 11\/64-inch diameter for easy integration into assemblies\u003c\/li\u003e\n  \u003cli\u003eCompact profile: 0.5 inches diameter, 0.375 inches high, 9\/32-inch gap width\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use Alnico button magnet for industrial fixtures, instrumentation, and mechanical assemblies requiring a Grade 5 Alnico permanent magnet in a 0.5-inch diameter button form.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by instrumentation technicians or mechanical assemblers. Ensure the mating surface is clean and free of ferrous debris before seating the magnet, as Alnico magnets are brittle and can chip if struck against hard surfaces. Do not attempt to re-magnetize or demagnetize this component without appropriate equipment. When mounting via the center hole, use hardware sized for an 11\/64-inch bore and avoid over-torquing, which can crack the magnet body.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.375 inches (9.53 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 11\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGap Width\u003c\/strong\u003e: 9\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pull Force\u003c\/strong\u003e: 1.5 lb (0.7 kg)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMagnet Material\u003c\/strong\u003e: Alnico 5 (Grade 5)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 550 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: ECLIPSE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E821\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ECLIPSE","offers":[{"title":"Default Title","offer_id":51701696921906,"sku":"E821","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2673085c9e385629de2c89d842795fca.jpg?v=1788403944","url":"https:\/\/voomisupply.com\/products\/eclipse-e821-alnico-button-magnet-0-5-in-1-5-lb-pull","provider":"Voomi Supply","version":"1.0","type":"link"}
