Optical Linear Encoder Read Head Linear Resolution 8μm To 32nm Easy
Installation
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.

Straight line: 8μm to 32nm Circle: up to 8 million/turn
· Accuracy
Straight line: ≤±3μm Circle: ≤±2.1arc-sec
· Speed
Up to 10 m/s motion speed
