G-17GLinear 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.SERIES 542 High-precision Linear GageLGH (0.01μm resolution)•A gage head featuring a very accurate, ultra-high-resolution photoelectric linear encoder that approaches laser interferometer performance over its measuring range of 10mm. This head is suitable for measuring high-precision components and inclusion in high-accuracy positioning applications.• Relatively long range, very high accuracy and extreme resolution enable the head to act as a master gage for measuring-instrument calibration in many instances.• The compact design contributes to reducing measuring system costs and permits downsizing entire system congurations.• Linear encoder is highly resistant to being affected by unfavorable environmental conditions, such as drafts and rapid atmospheric pressure, temperature and humidity changes.•A low measuring force model is available (542-716). As low as 0.12N can be selected, which enables measurement of easily-deformed workpieces or thickness of delicate lms.•Responsivity has been improved by 2.8 times (250mm/s => 700mm/s) compared to the previous model.•Every LGH series gage is bundled with a dedicated counter.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 542-715)• I/O output connector (with cover): 02ADB440SPECIFICATIONSLinear gaugeStandardLow measuring forceOrder No.542-715542-716Measuring range10mmResolution0.01μm (0.05μm, 0.1μm, 0.5μm, 1μm can be selected from the counter)Measuring accuracy (20°C)*0.2μmRepeatability (20°C)*0.1μm (2σ)Retrace error (20°C)*0.1μmMeasuring force Contact point downwards0.65N or lessApprox. 0.12NContact point horizontal0.55N or lessNot applicableContact point upwards0.45N or lessNot applicablePosition detection methodPhotoelectric reection type linear encoderDetectable operation speedIn normal measurement: 700mm/sec; for peak detection: 120mm/secMass of gage head220g (excluding cable of approx. 150g)Contact pointø3mm carbide-tipped (fixing screw: M2.5 (P=0.45)×5)Stem ø15mmBearing Linear ball typeOutput cable lengthApprox. 2mOperating temperature/humidity0 to 40°C/RH 20 to 80% (no condensation)Storage temperature-10 to 60°C/RH 20 to 80% (no condensation)Counter Quantizing error±1 countDisplay range±999.99999mmFunctionsPresetting, tolerance judgment, peak measurement, analog outputInterfaceRS-232C/Digimatic/USB (only for SENSORPAK)Power supplySupplied AC Adapter, or +12 to 24 V DC, max. 700mACurrent Consumption8.4W (MAX 700mA)(Ensure at least 1A power supply per unit.)External dimensions144(W)×157(D)×75(H)Mass Approx. 900g (AC Adapter excluded)Standard accessoriesWrench for contact point, rubber boot, stand, washer (for counter), AC Adapter, AC cord, DC plug, user's manual, inspection certicate*Indication accuracy applies when used with counters.Gage Head542-715Exclusive CounterAn inspection certicate is supplied as standard.
