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:

Parameter Description

Number of Graduations Total number of marks or divisions on the glass disc or scale
Subdivision Factor Number of signal periods per graduation mark
Signal Period Physical length of one complete cycle of the signal produced by the disc/scale
Index Mark Specific mark used as a reference point for position determination
Signal Output Type of electrical output signal produced by the disc/scale
Coating and Protection Coating or protective measures for durability and resistance
Material and Construction Material used and construction quality of the disc/scale
Size and Mounting Physical dimensions and mounting options of the disc/scale
Environmental Considerations Ability to withstand temperature, humidity, dust, and vibration
