Product Description
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). The slide carrier of the scales, use a five bearing design and six spring for optical grating linear transducer
b). Can connect a positive press system to reach waterproof IP65.
c). Moving speed can more than 120m/min.
Aging Test
Optical Linear Scale's reader head need to test for 72 hours aging test before assemble, make sure all linear scale's quality is reliable.

100% Laser calibration
All glass grating transducers 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 scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
