Absolute Linear Encoder Glass Scale With DRO Systems
Product Display
Advanced Optical Measuring System
Features:
1). VS series reader head's slide carrier, use five bearing design and six spring for optical grating linear transducer
2). VS20 series can connect a positive press system to reach waterproof IP65.
3). Moving speed can more than 120m/min.
Aging Test
Optical Linear Encoder's reader head need to power on testing for 3 x 24 hours aging test before assemble,
make sure all linear glass scale's quality is reliable.

100% Laser calibration
Easson 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.
