Digital Linear Encoder Linear Grating Scale 3 Axis Drilling Milling Lathe Grinder Position Scale With Readout
EA-927 all in one function DRO counter which have the functions are very important to machining, such as centering 1/2, PCD, INCL, R function, non-linear compensation etc.. For typical applications in manual machine tools such as milling or lathes, resolution 1 μm or 5 μm is sufficient to meet the application requirements. The linear encoders of the GS10 and VS10 series provide such a resolution with an accuracy class of ± 10 μm within 1meter travel range.

Digital readout power supply has a linear power transformer and power filter, this can help our products pass by the noice immunity and the EMC. To reduce the total heat generation inside the ES DRO in order to obtain long working life. An ultra low temperature rise transformer that construct with very high permeability icron core is used, which effectively bring temperature rise to only about 5℃.

EMC Testing equipment
To Make sure all Easson DRO products can be pass the standard EMC standard specification, we have a complete set of EMC test esd immunity tester.
Aging Test
Aging test can verify the process, design, material and other aspects are defective or not. We can using this testing promptly revises the product design to improve product quality and service life.
