It features a compact 8mm barrel diameter and an optical photoelectric encoder that delivers a resolution of 0.0001mm, making it suitable for high-accuracy dimensional inspection on production floors or in quality labs. The gage head carries an IP66 protection rating, allowing it to resist coolant splash and fine particulate contamination. A linear ball bearing in the spindle unit ensures smooth, repeatable travel over the full 0.4-inch (10mm) range. Licensed metrologists, quality technicians, and precision machining professionals are the primary installers and operators of this instrument.\u003c\/p\u003e\n\u003cp\u003eThe 542-188 is built for integration into automated or semi-automated gauging systems via its TTL output signal, which simplifies communication with PLCs, data acquisition systems, and remote display units. Its slim, robust displacement probe form factor fits into tight fixture arrangements where larger probes cannot reach. Typical applications include in-process dimensional checking, final inspection of machined components, and comparative gauging in both light manufacturing and tool-room environments. The 2-meter cable provides workable reach between the gage head and a remote display or controller without excess cable management burden.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOptical photoelectric encoder provides 0.0001mm resolution for high-accuracy displacement measurement\u003c\/li\u003e\n  \u003cli\u003eIP66-rated gage head resists coolant and particulate ingress in production environments\u003c\/li\u003e\n  \u003cli\u003eLinear ball bearing in the spindle unit ensures smooth, repeatable probe travel\u003c\/li\u003e\n  \u003cli\u003eTTL output enables direct communication with PLCs, remote displays, and data acquisition systems\u003c\/li\u003e\n  \u003cli\u003eCompact 8mm barrel diameter fits tight fixture and gauging station arrangements\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty, shock-resistant construction suited to continuous industrial use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style digital linear gage head for use with compatible MITUTOYO remote display units and gauging systems that accept TTL signal input.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified metrology technician or precision instrument specialist familiar with linear gage systems. Ensure the host fixture or mounting bracket is clean and free of burrs before seating the 8mm barrel to avoid misalignment errors. Power down any connected display unit or data acquisition system before connecting or disconnecting the gage cable. Avoid side-loading the spindle beyond the specified lateral measuring force, as this can affect accuracy and bearing life over time.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 0.4 inches (10mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eResolution\u003c\/strong\u003e: 0.0001mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.8+L\/50 micrometers\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBarrel Diameter\u003c\/strong\u003e: 8mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 125.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable Length\u003c\/strong\u003e: 2 meters\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisplay Type\u003c\/strong\u003e: Digital (Remote)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEncoder Type\u003c\/strong\u003e: Optical Photoelectric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutput\u003c\/strong\u003e: TTL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDownward Measuring Force\u003c\/strong\u003e: 0.55 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLateral Measuring Force\u003c\/strong\u003e: 0.60 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIP Rating\u003c\/strong\u003e: IP66 (Gage Head Only)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: 0 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 40 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.9 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: MITUTOYO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 542-188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MITUTOYO","offers":[{"title":"Default Title","offer_id":51562560815410,"sku":"542-188","price":1387.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22e2510d982866daa3c79522be861da8.jpg?v=1786479817","url":"https:\/\/voomisupply.com\/products\/mitutoyo-542-188-digital-linear-gage-0-4-inch-8mm-barrel","provider":"Voomi Supply","version":"1.0","type":"link"}
