High Accuracy VS Series Linear Encoder With 5um / 1um Resolution For Milling Grinder
Advanced Optical Measuring System
The slide carrier of the VS / VA series scales, use a five bearing design and six spring for optical grating linear transducer, specially in long dimension scale like the large Lathe machine. The Accuracy is better than the GS20 series long scale.
Features:
A). Reader head's slide carrier, use five bearing design and six spring for optical grating linear transducer
B). VS20 series can connect a positive press system to reach waterproof IP65.
C). Moving speed can more than 120m/min.
Aging Test
Easson Optical Linear Scale's reader head sensor need to power on for 72 hours aging test before assemble,
make sure all linear scale's quality is reliable.

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.
