What Does an Encoder Do?

When it comes to motion—speed, distance and direction—feedback systems, encoders of one type or another are typically at the core of the operation. Put simply, they record movement metrics and communicate them in a way that a control system and/or person can use to adjust or monitor. Encoders are critical components in all kinds of mechanical systems. They are especially prevalent in industrial settings where large machinery performs repeatable tasks, high-precision prototyping or delicate work.

Generally, encoders all do the same things, but the technology they use to do it can vary. These variations usually have the most impact on the detail and amount of feedback they provide. There can also be differences in how encoders are constructed based on the environments they are intended for.
