The scale delivers a resolution range of 0.001 inches down to 0.000005 inches (0.01 to 0.0001 mm), with a maximum measuring range of 21.26 inches (500 mm). The overall scale body length is 20 inches (696 mm total mounted length). Accuracy is rated at 0.0004 inches, making it suitable for applications where tight positional tolerances are required. Installation is performed by qualified metrology or CNC machine service technicians.\u003c\/p\u003e\u003cp\u003eThe AT113 series glass linear scale is used in CNC machining centers, grinding machines, milling machines, lathes, and coordinate measuring equipment where precise axis feedback is essential. It is appropriate for both light industrial and precision manufacturing environments. The scale carries an IP53 ingress protection rating, providing resistance to dust and low-pressure water spray, making it viable in typical shop-floor conditions. The 9.84-inch (3.00-meter) cable provides sufficient reach for most standard machine configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGlass scale construction for stable, low-thermal-expansion linear measurement\u003c\/li\u003e\n\u003cli\u003eResolution range from 0.001 inches down to 0.000005 inches (0.01 to 0.0001 mm)\u003c\/li\u003e\n\u003cli\u003eMaximum measuring range of 21.26 inches (500 mm)\u003c\/li\u003e\n\u003cli\u003eAccuracy rating of 0.0004 inches\u003c\/li\u003e\n\u003cli\u003eIP53 rated for dust and splash resistance in shop environments\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 0 to 45 degrees C with storage rated to -20 to 70 degrees C\u003c\/li\u003e\n\u003cli\u003e3.00-meter (9.84-inch) integrated cable for flexible installation routing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or upgrade linear scale for machine tools and metrology equipment compatible with AT113 series glass encoder scales requiring a 500 mm measuring range and standard encoder interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified CNC service technician or metrology equipment specialist. Power down and de-energize all machine axes before mounting or demounting the scale. Proper alignment of the read head to the scale body is critical — follow the machine or DRO manufacturer mounting tolerances. Avoid bending or stressing the cable at the connector junction during routing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: AT113\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Type\u003c\/strong\u003e: Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measuring Range\u003c\/strong\u003e: 21.26 inches (500 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eScale Length\u003c\/strong\u003e: 20 inches (696 mm overall)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.000005 to 0.001 inches (0.0001 to 0.01 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP Rating\u003c\/strong\u003e: IP53\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 9.84 inches (3.00 meters)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Temperature Range\u003c\/strong\u003e: 0 to 45 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStorage Temperature Range\u003c\/strong\u003e: -20 to 70 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 41111900\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MITUTOYO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 539-209-30\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51559137214770,"sku":"539-209-30","price":1575.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d6a133d9c40de5290da6cf5b675aa82_68d7a54b-6f2a-4350-b141-601a42fd4c69.jpg?v=1786428868","url":"https:\/\/voomisupply.com\/products\/mitutoyo-539-209-30-at113-linear-scale-500mm-glass","provider":"Voomi Supply","version":"1.0","type":"link"}
