It covers a measurement range from 0 to 1.00 inch with a resolution of 0.0001 inch and features a digital output interface for direct data transfer to compatible measurement systems. The thimble uses a ratchet-style drive mechanism for consistent measuring force, and the spindle lock secures the reading once a dimension is captured. A carbide measuring face resists wear during repeated use. Licensed technicians, machinists, and metrology professionals install and calibrate this type of head.\u003c\/p\u003e\n\u003cp\u003eThe CMS220519042 fits applications where a standalone micrometer head must be integrated into a fixture, bench stand, or automated gauging setup. Its 12.0 mm shank diameter and 17.5 mm shank length suit standard micrometer head mounting bores. The rotating spindle allows for zero-setting and positional adjustment without disturbing the workpiece. Data output capability makes it suitable for SPC data collection in production environments. It ships with a wooden storage box, a CR2032 lithium battery installed, and is calibrated to ASME B89.1.13 standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0 to 1.00 inch measurement range with 0.0001 inch resolution\u003c\/li\u003e\n  \u003cli\u003eDigital data output for SPC and direct computer interface\u003c\/li\u003e\n  \u003cli\u003eCarbide measuring face for extended wear resistance\u003c\/li\u003e\n  \u003cli\u003eRatchet thimble for repeatable, consistent measuring force\u003c\/li\u003e\n  \u003cli\u003eRotating spindle with spindle lock for precise zero-setting and position hold\u003c\/li\u003e\n  \u003cli\u003eCalibrated to ASME B89.1.13; includes wooden box and CR2032 lithium battery\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for integration into fixtures, stands, or gauging assemblies that accept a 12.0 mm shank-diameter micrometer head.

Secure the shank in the mounting bore using the appropriate clamp nut or collet-style holder; note that a clamp nut is not included with this unit. Verify that the spindle axis is aligned with the measurement axis of the fixture before locking down to avoid side-loading the spindle. Replace the CR2032 battery when the low-battery indicator activates to maintain measurement accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Range\u003c\/strong\u003e: 0 to 1.00 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Type\u003c\/strong\u003e: Ratchet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThimble Diameter\u003c\/strong\u003e: 18 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Shape\u003c\/strong\u003e: Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Diameter\u003c\/strong\u003e: 6.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpindle Length\u003c\/strong\u003e: 28.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 12.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 17.5 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 140.0 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Nut Type\u003c\/strong\u003e: Spindle Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasuring Face Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRotating Spindle\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eData Output\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBattery\u003c\/strong\u003e: CR2032 3V Lithium (included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCalibrated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ASME B89.1.13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncludes\u003c\/strong\u003e: Wooden Box\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.85 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.0 inches (L) x 3.4 inches (W) x 0.97 inches (H)\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: SPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CMS220519042\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SPIROTHERM","offers":[{"title":"Default Title","offer_id":51710265458994,"sku":"CMS220519042","price":210.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d97fe49bff9280d8bd79a2e10d3977dc.jpg?v=1788464964","url":"https:\/\/voomisupply.com\/products\/spi-cms220519042-electronic-micrometer-head-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
