Product Description
Linear Encoder, also called the grating ruler displacement sensor (grating ruler sensor), is a measurement feedback device that uses the optical principle of the grating. The grating ruler is often used in the closed-loop servo system of CNC machine tools, it can be used as a linear or angular displacement.
Advanced Optical Measuring System
The GS series scales of the slide carrier , use a five bearing design for optical grating linear transducer which has been proven as the most reliable system design in today's market.
Sealing Lip
GS series scales sealing lip use an innovative material to offer superior oil resistance, high elastic recovery properties and durability, carefully designed lips geometry offer low slide resistance.

Linear scale connector uses gold-plated pins to avoid poor contact,ensure it will not rust for long time usage.
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
Each linear scale is printed with a QR code, which is convenient for users to view the accuracy report of the factory inspection.
FAQ
1. Q: Did you accept OEM customized service?
A: Of course, we can provide not only typical products but also the products customized to customer's request based on the order quantity.
2. Q: What is your company mainly produce?
A: We are mainly produce Vision Measurement Machine, Optical Profile Projector, Digital Readout System(Counter), Linear encoder glass scale.
3. Q: Are the Length of this model has 1000mm?
A: Normally, GS90 series only available for the length 50 to 500mm, we don't suggest using this model for long dimension measuring due to its thin scale body structure(Insufficient rigidity).
4. Q: How can I identify Easson GS10, GS30 , GS90 , VS10 and VS20 model?
A: We has the product code label stick on the scale body, also each model deimension is different. For their structure, GS series using a five bearing design and one spring for Optical grating linear scale's carrier； But for VS series, it is totally different with GS which it has 6 spring push & pull structure, more accuracy than GS scale.
5. Q: How long dimension for the linear encoder scale you can produce?
A: Up to now, we can produce the maximum 3000mm long glass scale.
