A rotary encoder is a device used to determine the position, speed and direction of rotation. It consists of two main parts: a moving shaft and a sensor in a fixed position. A rotating object, the position of which is being evaluated, creates a movement that is detected by the sensor. This allows the encoder to determine the position of the object and how fast it is moving, in the main cases - by discretizing its position.
Rotary encoders are widely used in various industrial areas, such as robotics, CNC machines, the automotive industry and others, where accurate movement detection is necessary. These devices help to control, monitor and monitor the movement of systems, thereby ensuring their efficient operation and safety.
