G-19GLinear GageIdeal for integration into harsh environments such as automation applicationsMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.•Excellent measuring stabilityThe design is also highly resistant to unfavorable environmental conditions such as air movement and atmospheric pressure changes.•Low measuring force models are also available.Low measuring force models are available for easily deformed precision workpieces.•High-reliability and excellent durabilityHigh precision linear ball bearings are used in the spindle guide for extremely smooth movement and exceptional durability.SERIES 542 Super high-precision Linear Gage (Laser Hologage)LGH (0.01μm resolution)•The Mitutoyo Laser Hologage is a high-end digital gaging system that employs laser beam interference to make highly accurate and repeatable measurements.•The compact gage head reduces the costs required for assembling the laser scale unit for each device. The head can also contribute to downsizing the entire system. The master gage is the best tool available for measuring tools or for a length measurement sensor of the control unit, as well as for measuring high-precision components.•High resolution and high accuracyHighly accurate measurement due to an ultra-high resolution of 0.00001mm (0.01μm), which is close to the performance of laser interferometers.Optional Accessories• LGH stand: 971750• Stem xture for xing to top surface: 971751• Stem xture for xing to bottom surface: 971752• Spindle lifting cable: 971753• Rubber boot: 238752 (spare for 542-925 and 542-927)• I/O output connector (with cover): 02ADB440SPECIFICATIONSCode No.542-925*542-927*542-926*542-928*CongurationSet of 1-axis Gage Head and Display UnitSet of 2-axis Gage Head and Display UnitSet of 1-axis Gage Head and Display UnitSet of 2-axis Gage Head and Display UnitMeasuring range10mmMeasuring accuracy (20°C)0.1μm*1Repeatability (2)0.02μmRetrace error0.05μmMeasuringforceContact point downwards0.55N or less0.1NContact point horizontal0.45N or lessNot applicableContact point upwards0.35N or lessNot applicableContact pointø3mm carbide-tipped (xing screw: M2.5 (P=0.45)×5), standard contact point: 120058Output cable length2mDisplay range±999.99999mmMinimum reading0.01μmOperating temperature (humidity) range10 to 30°C (RH 30 to 70%, no condensation)Storage temperature (humidity) range–10 to 50°C (RH 30 to 70%, no condensation) The temperature and humidity range for storage after unpacking is the same as that for operation.Standard AccessoriesWrench for contact point: 538610AC adapter: 02ADN460AC cable (Japan): 02ZAA000*AC cable (USA): 02ZAA010*AC cable (EU): 02ZAA020*AC cable (Britain): 02ZAA030*AC cable (China): 02ZAA040*AC cable (Korea): 02ZAA050*Mass (Gage Head + Display Unit)1400g*1: Indication accuracy applies when used with counters.* To denote your AC power cable add the following sufxes to the order No.: A for UL/CSA, D for CEE, DC for CCC, E for BS, K for KC, C and No sufx are required for PSE.Laser Beam Safety PrecautionsThis system uses a low-power invisible laser beam (780nm) which corresponds to a CLASS 1 (invisible radiation) of IEC60825-1 for measurement. The CLASS 1 laser warning label as shown below is attached to the main unit.An inspection certicate is supplied as standard. Refer to page X for details.Gage Head542-925Exclusive Counter
