Copper Etching Custom Service Etched Encoder Disc for Optical Sensor




What is a Copper Etched Encoder Disk?


A Copper Etched Encoder Disk is a high-precision rotary sensing component made from a thin copper sheet using photochemical etching (PCE). It’s used in rotary encoders to accurately measure position, speed, and direction of a rotating shaft.


What it looks like

  • A thin copper disk

  • Precisely etched slots, lines, or patterns arranged radially

  • Patterns can be incremental (evenly spaced lines) or absolute (unique codes)

When the disk rotates, sensors read these patterns to generate signals.

Except Copper, What Materials We Use


We manufacture metallic encoder disks using high-quality materials to ensure stability, durability, and excellent corrosion resistance:


Stainless Steel Aluminum Nickel Titanium



Specifications of Copper Etched Encoder Disk


Thickness 0.1mm – 1.0mm
Outer Diameter 5mm – 300mm (customizable)
Etch Accuracy ±0.01mm (According to the thickness)
Surface Finish Matte / Bright / Passivated
Pattern Type Slots, lines, code patterns, or custom designs



How Copper Etched Encoder Disc Works

  1. The disk is mounted on a rotating shaft

  2. As it spins, light (optical encoder) or magnetic/electrical sensors detect the etched patterns

  3. The encoder converts these signals into data such as:

  • Rotation angle
  • Speed (RPM)
  • Direction of movement


Common Applications of Copper Etched Encoder Disc

  • Industrial rotary encoders

  • Servo motors & stepper motors

  • Robotics and automation systems

  • CNC machinery

  • Medical and precision instruments

  • Aerospace & defense positioning systems



Why Copper?

Copper is often chosen because it offers:

  • Excellent electrical conductivity

  • Good dimensional stability in thin gauges

  • Easy, precise etching for fine features

  • Cost-effective production for complex geometries

It’s especially suitable for photo-etched encoder disks with very fine line widths.

Why photochemical etching?

Photochemical etching allows:

  • Burr-free and stress-free edges

  • Extremely fine features (down to tens of microns)

  • No tool wear (unlike stamping or laser cutting)

  • High repeatability for mass production

This is critical for encoder accuracy.
