Product Description

Advanced Optical Measuring System

Features:

1. VS20 Linear encoder using a double T-slot design, which is convenient for users to install and correct the scale body.

2. VS20 Linear scale can be connected to a positive pressure system, the protection level can reach IP65.

3. Linear Encoder has three reference mounting surfaces, which can flexibly fit to various types of machine tools.

VA scale has a small PCB inside the 9 PIN connector, the laser compensation data is store inside, with our LCD Digital display unit, the compensation data will directly load the ECF file (compensation file) into the DRO, accuracy up to ±2μm.

Aging Test

Easson Optical Linear Scale's reader head need to power on for 24 x 3 hours aging test before assemble,

make sure all linear scale's is reliable working for long time.

100% Laser calibration

All linear encoder glass scale are individually inspected and calibrated by our in-house laser interferometer to ensure measuring accuracy comply 100% with the specifications.
