Common applications include coordinate and précision machine tools, coordinate measuring machines, microscopes and other high précision equipment. The System consists of an exposed scale and an encoder read head that works on the transmitted light principle. The scanning portion of the head self-aligns with the scale and thus maintains a constant gap between scanning unit and scale. The glass scale has a grating with two line tracks. One track is the periodic graduation with a constant line pitch of 20 iim. The second contains a référence mark, which can be located 40 mm from either end, from both ends, or in the middle of the measurement range. Unique location of référence marks can also be supplied upon request. The output signais are sinusoidal and phase shifted by 90°. With an external puise shaping and interpolation unit (available separately) one can obtain square wave outputs with resolutions of 0.5 iim, 0.2 jj.m or 0.1 iim. The System is available in three accuracy grades. Connector, interpolation unit and scale mounting clamp are optional based on customer's request. ■ Mechanical Data ♦ Measuring lengths (ML), mm 120, 170, 220, 270, 320, 340, 420, 470, 520, 620, 650, 720, 820, 920, 940, 1020 (othersMLonrequest) 20 um ±3; ±2 um ±lforML<320mm -middleofML - 40 mm from either end - 40 mm from both ends - others locations on request 18m/min ♦ Max.acceleration ♦ Requiredmovingforce ♦ Protection (IEC 529) ♦ Weight ♦ Coefficient oftemperature expansion ofglass scale ♦ Operatingtemperature ♦ Storage & Transportation température ♦ Permissible vibration (40 to 2000 Hz) ♦ Permissibleshock(ll ms) ♦ Relative humidity (without condensation ofmoisture) 40 m/s2 < 0.05 N IP00 (0.34+0.53xML)kg (MLmmetres) 8.5 um/m°C 0...+50°C -20...+70°C < 10 m/s2 <50m/s2 < 80% ♦ Standardgratingpitch ♦ Accuracy grades to any mètre withintheML(at20°C) ♦ Référence marks (RI): ♦ Max. traversing speed Read Head mounting possibility T I//I 0.05 1F h F - Machine Guideway ML - Measuring length
