How Do Magnetic Encoders Work?
Magnetic encoders use magnetic fields to track position and motion. As the encoder's disk rotates, it interacts with a magnetic sensor. This sensor detects changes in the magnetic field and generates an electrical signal representing the motion.
The controller then processes these signals, converting them into readable data on position, velocity, and direction. Magnetic encoders provide accurate and reliable feedback in both rotary and linear systems.
