COIN series incremental grating ruler
COIN series incremental grating ruler COIN
The COIN readhead integrates optical zero point and advanced optical filtering functions, combined with a unique flat optical structure, so that the overall thickness of the readhead is only 6.1mm while still having excellent dynamic performance. The automatic gain, automatic balance, and automatic correction functions enable the COIN readhead to ensure signal stability and low subdivision error even when the scale is contaminated or the installation deviation is large. The ultra-thin design of the read head integrates the interpolation box function inside, eliminating the need for an external interpolation box, making it easy to install and saving space. The positional installation tolerance of ±0.08mm reduces the difficulty of use.

The COIN readhead supports Banyan Optics' latest L-InSight function. With the help of specialized and powerful PC software, you can more easily gain insight into the working status of the COIN readhead. The COIN reading head supports two scale media: tape tape and circular code disc.
  • Integrated optical zero position, bi-directional zero return is repeatable.
  • The read head is internally integrated with subdivisions to save space.
  • High bandwidth, supporting maximum speed up to 8m/s.
  • Supports ABC, AOC, and AGC functions with low subdivision error.
  • The installation tolerance is large.
  • Multi-color LED on the reading head to conveniently indicate signal status.
