G-7GLinear 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 — Linear Gage Head with Origin Point MarkLGF-Z•LGF series with reference point signal output function.The master setting to use it, incorporated in the unit, is easy to operate. The origin point can be easily detected even when a fault, such as over-speed error, etc. occurs.•Sliding durability improved to remain serviceable for at least 15 million Cycles (in-house testing). •Shock resistance, 100g/11ms (IEC 60068-2-27)•Resolutions are available in 0.5μm or 1μm.542-174, -164542-175, -165Unit: mmConnectorSleeveø16.734.0(screw top height)10.6 or longer (stroke)Cable length, 2mDimensions with a thrust stem installedM9.5×0.5Attachment thread for thrust stemM9.5×0.5Clamp nut02ADB682Thrust stem02ADB681617.3ø8-0.009 012.33461.546.915.4ø16.73412(13.8)ø9.5-0.015 0414.59.514.80.675.7146.9 (129.5)545.9Rubber bootAttachment thread for thrust stemM14×0.5(screw top height)Cable length, 2m26 or longer (stroke)02ADB69202ADN371Clamp nutThrust stemM18×1Dimensions with a thrust stem installed18.595ø18-0.018 0(24.2)2134ø16.793.68.634(208.3)13.8ø15-0.015 061.730.720.64.584.1200.6114.76.522Rubber bootDimensions with a thrust stem installed(screw top height)Cable length, 2m51.5 or longer (stroke)M14×0.5Attachment thread for thrust stemM18×1Thrust stemClamp nut02ADN37102ADN37118.595ø18-0.018 0(24.2)2134ø16.71423413.8(316)0.6ø15-0.015 061.720.656.18.64.5124.9174629.620Rubber boot542-176, -166Optional Accessories• Air drive unitFor 10mm range models: 02ADE230For 25mm range models: 02ADE250For 50mm range models: 02ADE270* Required air pressure: 0.2 to 0.4MPa* Spindle extends when air is supplied.• Rubber boot (spare)For 10mm range models: 238772For 25mm range models: 962504For 50mm range models: 962505• Thrust stem setFor 10mm range models: 02ADB680Thrust stem: 02ADB681 Clamp nut: 02ADB682For 25/50mm range models: 02ADN370Thrust stem: 02ADN371 Clamp nut: 02ADB692* External dimensions are described in the dimensional drawing of the product.* Thrust stem set is a combination of thrust stem and a clamp nut. A special spanner is required for tightening. If using multiple gages, a thrust stem set for each gage and one special spanner are required.• Special spannerFor 10mm range models: 02ADB683For 25/50mm range models: 02ADB693•Extension cable ( 5m) : 02ADF260•Extension cable (10m): 02ADF280•Extension cable (20m): 02ADF300SPECIFICATIONSOrder No.542-174542-164542-175542-165542-176542-166Measuring range10mm (.4”)25mm (1”)50mm (2”)Resolution0.5μm1μm0.5μm1μm0.5μm1μmMeasuring accuracy (20°C)(1.5+L/50)μm (L=arbitrary measuring length (mm))Quantizing error±1 countMeasuring force Contact point downwards1.2N or less4.6N or less5.7N or lessContact point horizontal1.1N or less4.3N or less5.3N or lessContact point upwards1.0N or less4.0N or less4.9N or lessPosition detection methodPhotoelectric linear encoderReference mark position3mm from contact point tip (lowest rest point)5mm from contact point tip (lowest rest point)Reference mark repeatability (20°C): ≤0.5μm (at a constant reference point passing speed less than 300mm/s in the same direction)Response speed*11500mm/sOutput signal90° phase difference, differential square wave (RS-422A equivalent), minimum edge intervals: 250ns for 0.5μm model, 500ns for 1μm modelOutput square wave pitch2μm4μm2μm4μm2μm4μmMassApprox. 260gApprox. 300gApprox. 400gDust/water resistance*2Equivalent to IP66 (only gage head)Contact pointø3mm carbide-tipped (fixing screw: M2.5 (P=0.45)×5), standard contact point: 901312Stem dia.ø8mmø15mmBearing typeLinear ball bearingOutput cable length2m (directly extended from the main unit)ConnectorPlug: PRC05-P8M (TAJIMI), Compatible receptacle: PRC05-R8F (TAJIMI)Operating temperature (humidity) range0 to 40°C (RH 20 to 80%, no condensation)Storage temperature (humidity) range–10 to 60°C (RH 20 to 80%, no condensation)Standard AccessoriesWrench for contact point: 538610Wrench for contact point: 210187Remarksw/ origin point mark*1: When the spindle speed exceeds 1500mm/s, an alarm signal will be output. For use of alarm signals, please inquire separately. For models with 50mm stroke, note that over-speed error may occur depending on the impact amount when releasing the contact point freely.*2: IP Code is a standard which classifies and rates the degree of protection provided against the intrusion of solid objects and water.
