Reflective Open Grating Scale Advantages:
- Achieve the highest possible measuring repeatability that your mechanical structure is designed and built.
- Provide the best possible low speed high precision counting servo movement control for your machines or linear motor.
- thin reader head housing which offer two different installaion direction
- High resolution: 0.02μm ( 20 nanometer )
- maximum measuring speed up to 180m/min
- acceleration up to 4G
Three choices of measurement accuracy : ±3 μm, ±5 μm, ±10 μm
Installation Dimensions
Thanks to the small reader head size, this makes your scale installation very easy and convenience, there are two types of installation direction fixing the reader head.
TYPE A
TYPE B
