Advanced Optical Measuring System
1. Six-spring & push-pull structure to ensure repeatability less than 2 micron；
2. Advanced engineering mechanics analysis and design to ensure that the dynamic speed more than 120 m/min
Aging Test
The aging test exposes defects in the process, design, materials and other aspects of electronic devices before leaving
the factory. Therefore, it is of great significance for companies to modify product designs in time, so that products can be sold
after they are aging and stable, improving Easson product quality and market reputation.
100% Laser calibration
All linear encoders are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
Accuracy report in QR code
Each linear encoder is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
