GS64 Reflective Open Grating Scale Apply to PCB Drilling Machines
GS64 is special designed for high speed & high accuracy Metrology equipment, for example, high speed PCB drilling machines, linear motors ... or etc. GS64's unique non-contact Phased Array refelective open grating measuring system offers high precision backlish free position eadings.
GS64 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 GS64 is 0.1μm, maximum measuring speed up to 60m/min, acceleration up to 4G.
Three choices of measuring accuracy : ( ±10 μm / ±5 μm / ±3 μm ) are available to achieve the best price-performance for your application.
Installation Dimensions
Thanks to the small reader head size, this makes your scale installation much more easy & convenience. More than that, there are two types of installation direction fixing of reader head housing available for your choice.
TYPE A
TYPE B
Grating Glass Dimension
They are 6.2mm x 1 mm glass, 12 mm x 2 mm glass, and 12 mm x 3 mm glass three dimension for the grating glass.
