What is a Rotary encoder?

A rotary encoder is a type of sensor that converts rotational motion into digital signals, primarily used for measuring the position or rotational angle of machinery. A rotary encoder tracks the angle of a rotating shaft continuously and generates output signals based on that angle. There are two main types of encoders: absolute encoders, which measure the rotational angle as an absolute value, and incremental encoders, which measure the change in rotation. This allows for precise control of machinery position and monitoring of movement. Rotary encoders are used in a wide range of applications, including industrial machinery, robotics, and motor control systems.

Application of Rotary encoder

✅ Position Control in Industrial Robots
In industrial robots, rotary encoders are used to control the precise position of arms and tools. This allows for accurate tasks and automation processes to be performed.
✅ Rotary Axis Control in CNC Machines
In CNC (Computer Numerical Control) machines, rotary encoders monitor the movement of rotary axes to ensure precise machining. This improves the accuracy of the machine and enables efficient production.
✅ Motor Control Systems
A rotary encoder mounted on a motor provides feedback on the rotation speed and position, controlling the motor's operation in real-time. This ensures stable performance and precision in motor-driven systems.
✅ Position Monitoring in Elevators
Rotary encoders are used in elevator shafts to track the position of the elevator car accurately. This helps in safely and efficiently controlling the elevator's operation.
