High Accuracy Vertical 6 Springs Design Linear Encoder Glass Scale with Digital Readout System

Product Specification

Obviously, linear scales are essential for success involving workpieces and machine tools, because without the right measurement, you can’t get the right fit. And, without the right fit, you won’t have a successful outcome with the workpiece. In order to avoid wasting materials, time, energy, and money, it’s important to have a well-calibrated linear scale on hand for use of machine tools like power saws, turning machines, and milling machines.

Alliance calibration specializes in ensuring accuracy where it’s most needed, like in precision tools. The linear scale is one of many items that we work on. With a unique design for reading the measurements of motion and position, the linear scale promises accuracy in your machine tools, as long as the linear scale is properly calibrated.

Most modern linear scales are digital and come with an LCD display that shows a clear and exact read. Linear scales provide a very specific service. These measurement tools offer a clear read on the distance between two points by reading the motion along the path of the scale. In this way, linear scales can provide the exact dimensions of workpieces so that they can be worked on properly. By obtaining and maintaining the exact measurement with a linear scale, one can ensure that the workpiece sits properly in a machine tool, which ensures accuracy in manufacturing.

Installation Dimensions

VA20 Series

Connector interface

Easson absolute linear encoder use Gold-plated pins to avoid poor connection and Anti-corrosion, it has a 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

Product Description

Advanced Optical Measuring System

The slide carrier of the VS / VA series scales, using 5 bearing design and 6 spring for optical grating linear transducer, make sure the VA scales not effected by installation, the spring can adjust the angle when the operator install not good for the alignment.

The reader head still in the best way fit on the grating glass, the accuracy of VA scale is totally different with the GS or other brand in China mainland.

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.

Easson was established since 1995.It is a high-tech enterprise specializing in design and manufacturing of precision measuring equipment, obtained more than 20 national invention and utility model patents. Our product field in DRO systems, precision optical profile projectors, video measuring machine and etc..

Easson's factory building is specifically design and built for the manufacturing of precision measuring equipment, has four Laser interferometers for being the company's length measurement standard and R&D.

Easson is one of the few companies in the industry that has its own high-precision grating master which use own fully-developed grating master lithography equipment, produce the absolute linear encoder and high accuracy CNC linear encoder.

Our quality management system has been assessed and registered by National Quality Assurance Ltd.(NQA) against the provision of ISO 9001:2015.

Strong Technical Capabilities And Scientific Research Resources

Over the years, the company has established a very close and effective cooperative relationship with scientific research institutions such as Xi'an Jiaotong University and Jilin University, taking advantage of the abundant talents and theoretical advantages of university scientific research institutions, combined with the company's long-term accumulated technology and practical experience in this industry , so that we have created many products that are leading the domestic industry.

In addition, the company actively participates in the scientific research and industrialization projects issued by the state and Zhuhai City.

For example, in 2011, the company participated in the "High-end CNC Machine Tools and Basic Equipment" led by Xi'an Jiaotong University and issued by the Ministry of Industry and Information Technology of China "Science and Technology Major Project. And combined with Tianjin University, Hefei University of Technology, Chinese Academy of Metrology... and other units jointly developed.

The company's AS-40 series grating ruler is one of the results of this project, which is industrialized by our company. And our company's EC-2 Pseudo-random absolute coding is one of the project achievements jointly developed by our company and Jilin University.
