Encoders

An encoder is a hidden hero in dozens of applications, from medical diagnostic devices to printers to industrial drilling machines. The highly precise sensing device provides motion feedback to electronics that control the motion of a device or machine.

Encoder wheels, encoder discs, and encoder strips are essential parts of an encoder, and each part must be fabricated to the most stringent specifications.

PEI excels in manufacturing custom encoder wheels and discs tailored to our client’s specifications. Leveraging our expertise in precision photochemical etching our encoder components are engineered with unparalleled precision and maintain strict dimensional tolerances.

What is an encoder?

An encoder is a sensing device that provides critical feedback by converting motion into electrical signals, which control devices in industrial electronics and motion control systems can interpret.

We know their integration into complex electronic devices and systems, encoders, encoder disks, encoder wheels, and encoder strips necessitate intricate and precise engineering to perform reliably and effectively.

The work we've done

What is photochemical etching?

Photochemical etching, also known as precision chemical machining, chemical blanking, or acid etching, is an exact subtractive manufacturing process where chemical etchants selectively remove metal from a thin sheet to create intricate shapes, patterns, and features. Unlike traditional methods, photochemical machining does not involve mechanical force or direct contact with the sheet of metal, minimizing the risk of distortion, burrs, or stress-induced deformation.

What are the benefits of precision chemical machining for encoder wheels, discs, and strips?

The benefits of photochemically etching encoder parts include fabricating precise parts with intricate geometries and accurate patterns.

Here are additional benefits of titanium photochemical etching:

  • Burr-free parts, removing the need for secondary finishing or cleaning
  • No mechanical or heat stress on the metal sheet
  • Rapid prototyping and production scalability
  • Cost-effective production process
  • Freedom to design complex and intricate patterns
