What Is an Encoder? Basics of How It Works

Encoders are essential components in today’s automation and motion control systems. They convert motion to an electrical signal that can be read by some type of control device, such as a PLC or a microcontroller. If you’ve ever wondered how machinery precisely detects position and speed, or how robotic arms know where to move, this article is for you. We’ll explore the fundamentals of encoders, their types, and their crucial role in various applications.
