Optical Encoder Open Non-Contact Grating Reading Head Grid Spacing 256μm
The HXC grating system is based on an innovative non-contact optical structure.
This design in the realization of zero mechanical lag and accurate measurement at the same time, but also has a strong anti-fouling ability, such as dust, light oil stains and scratches, does not affect the integrity of the signal. These ensure that the machine can run reliably without too much maintenance.
The HXC grating system is used in all areas of industrial automation, such as semiconductor, electronics, medical, scanning, printing, scientific research, space measurement, imaging and special machine tools, including precision measurement and motion systems. Generally speaking, precision motion control requires the use of precision feedback gratings.
