What is an Optical Encoder?

In precision engineering, optical encoders are the cornerstone of control. But what exactly is an optical encoder?

An optical encoder converts rotational motion into digital signals using a light source, a rotating disc with windows, and sensors that detect light changes. As the disc rotates, it triggers sensors that convert changes in light intensity into electrical signals, providing accurate data on speed, position, and direction. 

Optical encoders rely on light and sensors to detect motion without physical contact between the moving parts. Their non-contact operation minimizes wear, enhancing durability and reliability.

From industrial automation to robotics, medical devices to aerospace, optical encoders empower engineers and innovators to push boundaries and unleash the full potential of their designs. Operate with confidence, powered by the precision of Grayhill’s optical encoders.
