GS65 High Accuracy Reflective Open Grating Scale
GS65 series exposed linear encoders operate with no mechanical contact between the scanning head and the scale or scale tape. Typical areas of application for these encoders include measuring machines, comparators and other precision devices in linear metrology, as well as production and measuring equipment, for example in the semiconductor industry.
Product Features
- Phased Array Grating Measurement System
- Readout Resolution : 0.02 μm ( 20 namo meter)
- Measurement Speed : 180 m / min
- Acceleration : 4 G
Advantage of high speed readout resolution ( 20 nano meter )
- 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.
There are three choices of measurement accuracy in GS 65 series, there are ±3 μm, ±5 μm, ±10 μm
Installation Dimensions
Since the small reader head size, this makes the installation so easy and convenience. More than that, there are two types of installation direction fixing of reader head housing available for your choice.
TYPE A
TYPE B
Grating Glass Dimension
| Glass Dimension | High(mm) | Thick(mm) | Meas. Travel(mm) |
| G1 | 6.2 | 1.0 | 120 |
| G2 | 12 | 2.0 | 500 / 1000 |
| G3 | 12 | 3.0 | 1200 - 3000 |
In the GS65, there are 3 types of different grating glass dimensions, they are 6.2mm x 1 mm glass, 12 mm x 2 mm glass, and 12 mm x 3 mm glass.
