DTTL CMM Metrology Equipment Exposed Linear Encoders
Product View
Exposed linear encoder applications in high speed and high accuracy metrology equipment, CNC vision measuring machines, length measuring machine, coordinate measuring machine(CMM), 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 Reflective Open Grating Scale Advantage
- Achieve the highest possible measuring repeatability that your mechanical structure is designed and built.
- Provide the best possible low speed high precision counting servo movement control for your machines or linear motor.
- Smallest grating scales provide two different installation direction
GS65 standard resolution is 0.02μm ( 20 nanometer ), maximum measuring speed up to 180m/min, acceleration up to 4G.
