Easson VA11 Absolute Linear Encoders

Vertical 5 Bearings Absolute Linear Encoder with Digital Readout Dro

Product Description

Advanced Optical Measuring System

Principal of Absolute Linear Scale

The grating scale of absolute linear scale consists of two grating masks, they are Absolute Grating Mask and Incremental Grating Mask respectively. Functions of this two masks are as per follows :

Absolute Grating Mask have different mask pattern over the whole grating glass, it gives low resolution but unique position readings over the whole measurement travel.

Incremental Grating Mask is an identical repeatable mask patterns over the whole grating glass, it gives very stable and high quality electronic signal for signal interpolation to achieve very high accuracy and resolution position readings.

Absolute Coding

All absolute coding used in our Absolute Grating Mask are designed by Easson, it is 100% our in-house design and intellectual property, designed and developed for different requirements of applications.

Product Specification

Installation Dimensions

VA10 / VA11 / VA12 / VA13 Series

Connector interface

Gold-plated pins to avoid poor connection and Anti-corrosion, it has  the small PCB inside the connector which allow the VA series Absolute Linear Scale built in the Laser compensation data and directly connect to our LCD DRO, ensure the high measuring accuracy.

DSUB 9PIN

100% Laser calibration

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

Accuracy report

Each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
