What is a Optical encoder?

An optical encoder is a sensor used to precisely measure rotational or linear motion by utilizing optical technology. It works by reading patterns (such as holes, lines, or slits) etched on a disk with a light sensor, detecting position and speed. The motion or position of an object passing between a light source and a detector generates a digital signal, enabling precise control. Optical encoders are non-contact and offer high accuracy, making them widely used in industrial equipment, robotics, and motion control applications.

Application of Optical encoder

✅ Robot Positioning
Optical encoders are used in robotic joints and arms for precise positioning. Accurate position measurement enables precise control of robotic movements.
✅ CNC Machine Precision
In CNC machines, optical encoders monitor the position of tools with high precision, improving machining accuracy and control during operations.
✅ Camera Autofocus Mechanism
Optical encoders are used in camera autofocus systems to accurately measure the position of the lens, allowing for precise focusing.
✅ Automobile Steering Systems
In automotive steering systems, optical encoders measure the steering wheel's rotation angle precisely, sending signals to the servo motor for control.
