Pivotal to an automation system’s success is a rotary encoder, which provides information about the motion of motor shafts, pulleys, robot arms, and other functions. Improve your application with custom encoders from Microphoto.

What Are Encoders? 

Encoders are electromechanical devices that convert rotational mechanical displacements into electrical signals and process those signals. Comprised of optically opaque material piecces filled with regularly shaped transparent openings or holes, they’re typically paired with a light source and photodetector to determine a moving object’s position, direction, or speed – or all three of them.

Types of encoders include a rotary, shaft, mechanical, optical, magnetic, and electromagnetic. Most common automated subassemblies for many applications.

Leading Encoder Manufacturer

Microphoto provides photochemical etching and chemical milling solutions for commercial and industrial applications. With a full suite of value-added services, we can take an encoder design from print to production quickly and affordably.

  • Metal Stamping
  • Metal Laser Cutting
  • Wire EDM Machining
  • NADCAP Heat Treating
  • Metal Plating and Finishing
  • Non-Destructive Testing, or NDT
  • Metal Surface Finishing And Edge Rounding
  • Progressive Die Blank Development

We specialize in short to long-run, low to high volume manufacturing of encoders using your print, specification, or purchase order requirements. But, of course, those with a unique need but no approved design are welcome, too.

Our experts can work with you to develop a concept and make a prototype. Production of the complete order begins when the design is approved.

Why Are Chemically Etched Encoders Better?

Microphoto can manufacture custom encoders to meet your unique specifications using precision photochemical machining techniques. The process leverages chemicals to remove material in designated areas to produce the finished product.

Etched metal encoders have no burrs using the photochemical etching process. That means there are no stress-risers on the part profile, enabling it to withstand millions of cycles without a stress fracture.

Additionally, chemical etching doesn’t alter the remaining material in any way. There’s no heat-effected zone or work hardening, and the part profile mirrors the CAD file in smoothness, without striations of any kind.

Precision Applications, Quality Materials 

Whether your blueprint is complex or straightforward, photochemical machining can produce custom encoder discs that match your exact requirements. In addition, there are essentially no limits to the designs that our team can deliver. Materials we work with include:

  • Silver
  • Copper
