50-500 mm Position DRO Micro Linear Encoder For Drilling Lathe Machine

Optical Micro Linear Encoder Glass Scale Special For Drilling Lathe Machine

Linear encoder are used in various machines with digital readout System, which is often used to detect the coordinate of the tool and the workpiece. Also used in the closed-loop servo system in CNC machine tools, and can be used as a linear or angular displacement.

Working Principle

Taking a transmission grating as an example, when a small angle θ is formed between the line pattern on the indicator grating and the line pattern on the scale grating, and the two grating scale facets are placed relatively parallel, under the illumination of the light source, they are located almost perpendicular On the grid pattern, light and dark stripes are formed. This kind of fringe is called "moiré fringe"

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.

Installation Diagram

Connector interface

DSUB 9PIN

Linear encoder connector use gold-plated pins to avoid poor contact,ensure it will not rust for long time usage.

100% Laser calibration

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

Accuracy report

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

FAQ

1. Q: What's your factory mainly produce?

A: We are mainly produce CNC Video Measuring Machine, Optical Profile Projector, Digital Readouts(DRO), Linear encoder grating ruler, CNC linear encoder.

2. Q: Did the travel length of GS90 series has over 1000mm long?

A: Normally, GS90 travel length is available from 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).

3. Q: How can I identify Easson GS10, GS30 , GS90 , VS10 and VS20 model?

A: We have the product code label 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；However for VS series, it is totally different with GS because it has 6 spring push & pull structure, more accuracy than GS scale.

4. Q: How long can you produce for the linear encoder ?

A: Maximum is 3000mm.

5. Q: How can I check Easson linear encoder scale accuracy report?

A: User can use the mobile phone which has scanning QR code function(eg. Wechat, browser etc.) to scan the linear scale QR code.

6. Q: What about the products warranty?

A: 13 months from the date of shipment.

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.
