How to choose encoder glass discs?

To choose the glass discs and scales for encoder, we have to consider:

  • -Consider the required resolution and accuracy for your application.
  • -Assess the signal quality, ensuring minimal noise and reliable data output.
  • -Evaluate the glass disc's suitability for the environmental conditions.
  • -Check compatibility with mounting options and electrical interfaces.
  • -Look for durability and longevity to ensure long-term reliability.
  • -Consider the cost and balance it with the required performance.
What are the key parameters to consider?

We have to consider key parameters of glass discs and scales as follows:
