Get a Quote

High-resolution plastic or glass encoder discs are the latest technology for highly reliable manufacturing processes and high-tech product lines.

They feature resolutions up to 1,270 lpi and made of polycarbonate, PET film or soda-lime glass with temperature ranges up to +120°C. Discs can be transmissive or reflective with A, B, and D signals.

These high resolution encoder discs are a perfect match for OEM applications to control speed and timing of electric motors, robots, printers and scanners, computer sewing machines, etc. Double-sided tape and hubs are also available for mounting.

  • Circular, linear and custom designs available
  • Low cost
  • RoHS compliant
