What is the function of rotational encoder?

A rotary encoder is a crucial sensor in motion control systems, designed to measure and monitor rotational movement. Its primary function is to convert the angular position or speed of a rotating shaft into electrical signals (digital or analog), enabling precise control in automated applications.

Key Functions of Rotary Encoders:

1. Position Feedback – Provides real-time data on the shaft’s angular position, essential for robotics, CNC machines, and servo motors.

2. Speed Measurement – Tracks rotational speed (RPM), used in conveyor belts, industrial motors, and automotive systems.

3. Direction Detection – Determines clockwise or counterclockwise rotation, critical for automated guidance systems.

4. Motion Control – Ensures synchronization in multi-axis systems, improving accuracy in manufacturing and automation.
