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.
