Product Introduction
GS65 exposed linear scale is designed for high speed and high accuracy applications such as video measuring machines, PCB drilling machine, coordinate measuring machine, linear motors ... etc. GS65's unique non-contact compensated Phased Array refelective open grating measuring system offers high precision backlish free position readings.
GS65 High Accuracy Exposed Grating Scale Advantage
GS65 is one of the smallest grating scales in this planet, available in two types of minature reader head housing, which offering two different installation direction respectively, making your scale installation exteremely easy.
Standard resolution for GS65 is 0.02μm ( 20 nanometer ), maximum measuring speed up to 180m/min, acceleration up to 4G.
