Linear Encoder

A linear encoder is a high-precision sensor used to measure linear displacement and position changes. It directly converts the linear motion of an object into an electrical signal output, enabling real-time detection and feedback control of position, velocity, and displacement changes. The structure of a linear encoder typically consists of a scale (such as an optical or magnetic scale) and a reading head. When the object being measured moves along a straight line, the reading head senses changes on the scale through optical, magnetic, or inductive methods and converts these changes into continuous electrical or digital signals for output.

In terms of technical principles, common types include optical encoders, magnetic encoders, and inductive encoders. Among them, optical encoders offer the highest precision and are suitable for high-end CNC and semiconductor equipment, while magnetic encoders have strong resistance to contamination and are more suitable for environments with high vibration and dust. In addition, SUCH linear encoders can achieve a resolution down to the micrometer level, significantly improving the processing accuracy and repeatability of equipment, making them an excellent choice for linear displacement detection.
