It delivers a resolution of 0.0005 inches, making it suitable for machine tool feedback, coordinate measuring systems, and precision positioning equipment. The scale spans 124 inches in length, accommodating large-travel linear axes without sacrificing measurement integrity. Accuracy is rated at 25+5L micrometers per 1,000 meters of travel, providing a quantifiable error budget for engineers and calibration technicians specifying the unit for controlled environments. Installation is typically performed by metrology technicians or precision machine builders.\u003c\/p\u003e\u003cp\u003eThis scale is used in applications requiring continuous, high-resolution linear position feedback over extended travel distances. Typical installations include large-format CNC machine tools, gantry systems, precision grinding machines, and industrial coordinate measuring equipment. The electromagnetic sensing technology provides durability in environments where optical contamination from coolant, chips, or debris may affect optical encoder performance. Its 124-inch active length supports large-bed machining centers and multi-axis positioning stages common in aerospace, mold-making, and heavy manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0005 inch resolution for precise linear position feedback\u003c\/li\u003e\n\u003cli\u003e124 inch scale length supports large-travel axis applications\u003c\/li\u003e\n\u003cli\u003eElectromagnetic sensing technology resistant to optical contamination\u003c\/li\u003e\n\u003cli\u003eAccuracy rated at 25+5L micrometers per 1,000 meters of travel\u003c\/li\u003e\n\u003cli\u003eSuitable for CNC machine tool, metrology, and precision positioning systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style linear scale for industrial machine tool and precision metrology systems requiring electromagnetic position feedback over extended travel lengths.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of linear scales should be performed by qualified metrology technicians or precision machine builders familiar with encoder mounting tolerances and alignment procedures. Power down all machine axes and control systems before mounting or wiring the scale. Follow the machine builder and scale manufacturer specifications for mounting gap, parallelism, and read-head alignment. Secure all cable routing to prevent interference with moving machine components during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Electromagnetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Length\u003c\/strong\u003e: 124 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 25+5L micrometers per 1,000 meters\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 20 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SONY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: SL220-120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SONY","offers":[{"title":"Default Title","offer_id":51541347139890,"sku":"SL220-120","price":5194.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60ea5ac61e9bf1a46f0908135bb20c44_21b8c0bb-59f3-4574-a433-6daf4e65d56e.jpg?v=1785873142","url":"https:\/\/voomisupply.com\/products\/sony-sl220-120-electromagnetic-scale-124-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
