Optical Encoder Accurate Measurement Linear And Circular Grating Ruler Optional
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 known in the industry for their ease of installation. The grid ruler is available in a variety of lengths, and the special design of self-adhesive on the back enables the installation without drilling screws, thus saving time and cost. All reading heads and interfaces are monitored by patented LED installation status indicators, increasing installation speed and eliminating the need for oscilloscopes and other complicated installation monitoring.
