Encoders are devices designed to convert mechanical motion or position changes into electrical signals for position feedback or motion control applications. These devices utilize different encoding techniques such as optical, magnetic, or capacitive principles to track the rotational or linear displacement of shafts, wheels, or actuators accurately. Encoders find applications in industrial automation, robotics, CNC machines, servo motors, and motion control systems for tasks such as position feedback, speed control, and motion synchronization. They offer advantages such as high resolution, accuracy, and reliability, making them essential components in precision motion control and positioning applications.
