G-29GLinear 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 318 LitematicVL-50-B/50S-B•The Litematic is designed for measuring easily-deformed workpieces and high-precision parts, with extra-low measuring force of 0.01N.•0.15N and 1N types are capable of measuring at a certain measuring force by using a Litematic feature, while the 0.01N type is suitable for measuring delicate workpieces.*1: 0.15N, 1N types are factory-installed option.•The motor-driven spindle moves up/down and stops when the contact point touches the workpiece. Then the maximum, minimum values, and runout value are measured under a constant force.•High resolution of 0.01μm, and wide measuring range of 50mm.•Measuring system VL-50-B, integrated display type, and VL-50S-B, a separate display type, are available.•The measuring table supplied with VL-50-B is ceramic, corrosion-free for easier maintenance and storage.•The spindle is made of low thermal expansion material.•Motor life is approximately 100,000 opera-tions, after which replacement is advisable.This machine is not suitable for continuous use, such as on a production line.Optional Stand for VL-50S-B 15 250 80 270 ø50 300 48 80 56 157 Clamp screw 365 ColumnHeight adjustment nutBaseBracketHex socket set screw(4-M4×0.7)Litematic headUnit: mm957460Optional Accessories• Foot switch: 937179T• Dedicated stand: 957460*4• SPC cable (1mm): 936937*5• SPC cable (2m): 965014*5• VL weight part: 02AZE375*6• Recommended spare contact point: Shell type Carbide-tipped spherical contact point, ø7.5 Carbide-tipped spherical contact point, ø10.5 Carbide-tipped needle contact point, ø0.45*4: Only VL-50S is available. *5: Refer to page G-32 for details of the RS link.*6: Not applicable to VL-50-100-B, VL-50S-100-B.SPECIFICATIONSOrder No.318-221*318-222*318-223*318-226*318-227*318-228*Measuring range0 to 50mm (0-2")Resolution0.01/0.1/1.0μm (.0000005"/.000005"/.00005")Display unit8 digits/14mm (.6") character height (without signs)Scale typeReflection type linear encoderStroke51.5mm (.2") (when using a standard contact point)Indication accuracy (20°C)*1(0.5+L/100)μm L=arbitrary measuring length (mm)Accuracy guaranteed temperature*220 ± 1°CRepeatability*1=0.05μmMeasuring force*10.01N0.15N*31N*30.01N0.15N*31N*3Feed speedMeasurementApprox. 2mm/s (.08"/s) or 4mm/s (.16"/s) (changeable by parameter)Fast feedApprox. 8mm/s (.3"/s)Contact pointø3mm carbide-tipped (fixing screw: M2.5 (P=0.45)×5), standard contact point: 901312Measuring tableø100 (ceramic, grooved, removable)—InputFoot switch input (when optional foot switch is used)External ControlOutputDigimatic output/RS-232C output (changeable by parameter)RatingPower supply85 - 264V AC (depends on AC adapter)Power consumptionMax. 12 W (12V, 1A)Standard AccessoriesAC adapter: 357651, Power cable/grounding wire: 02ZAA000, AC cable (Japan): 02ZAA000*AC cable (USA): 02ZAA010*AC cable (EU): 02ZAA020*AC cable (Britain): 02ZAA030*AC cable (China): 02ZAA040*AC cable (Korea): 02ZAA050*Hex wrench (2 pcs, for fixing contact point and for removing fixing bracket)*1: Normal measurement using standard contact point.*2: Under less temperature change, and hot or cold direct air flow should be avoided.*3: 0.15N, 1N types are factory-installed option.Note: To denote your AC power cable add the following suffixes to the order No.: A for UL/CSA, D for CEE, DC for CCC, E for BS, F for SAA, K for KC, C and No suffix are required for PSE.318-226318-221
