Encoders 101: An Introduction to Encoders

What is an Encoder? | Where and How Encoders Are Used Encoders are motion feedback devices that convert mechanical motion into electrical signals, allowing machines to accurately monitor position, speed, and direction. In this video, we break down what encoders are, how they work, and where they’re used across a wide range of industries. Encoders are essential components in automated systems, providing the precise motion feedback required to control machinery. They come in various types—rotary, linear, incremental, and absolute—each designed for specific applications. In this video, you'll learn how encoders are used in: Material Handling – for conveyor speed control, positioning, and automated sorting. Packaging – in cut-to-length applications, registration mark detection, and labeling systems. Robotics – to track joint positions and enable accurate, repeatable motion. AGVs/AMRs (Automated Guided Vehicles) – to provide wheel feedback and navigation data. Metal Fabrication and Machine Tools – for positioning of cutting heads and press brake control. Plastics Forming and Wire/Cable – in extrusion, take-up/reel systems, and spooling. Aerospace, Automotive, and Electronics – in precision assembly, quality inspection, and process control. Encoders are the unseen precision behind automation—and in this video, you’ll see how Encoder Products Company delivers reliable, customizable encoder solutions built to meet the demands of modern industry.
