Axial Incremental Magnetic Ring, for Rotary Magnetic Encoders

Description:

Since the magnetic encoder possesses a mechanism to detect changes in the magnetic field, it boasts excellent robustness in environments contaminated with dust, oil, and water. Therefore, it is particularly suitable for use in settings with significant amounts of dust, oil, and water. For instance, magnetic encoders are employed in industrial sewing machines operating in environments Laden with lint, and machine tools are used in situations where they generate oil and water splashes during operation.

Advantages and applications of magnetic encoder

Since the magnetic encoder possesses a mechanism to detect changes in the magnetic field, it boasts excellent robustness in environments contaminated with dust, oil, and water. Therefore, it is particularly suitable for use in settings with significant amounts of dust, oil, and water. For instance, magnetic encoders are employed in industrial sewing machines operating in environments Laden with lint, and machine tools are used in situations where they generate oil and water splashes during operation.

Another advantage is that it is feasible to manufacture an encoder that outputs an absolute angle utilizing a simple structure consisting of a rotation angle sensor IC and a permanent magnet. Consequently, it is ideal for applications that demand a compact size, lightweight nature, and high reliability. For example, it finds its application in machine tools employing small-diameter motors and factory automation machines requiring durability.

In general, optical encoders are utilized in applications demanding high precision and resolution, while magnetic encoders are preferred in applications that prioritize environmental robustness, compactness, and high reliability. However, given the improved accuracy and resolution of contemporary magnetic encoders, coupled with their compatibility with hollow-through shafts, magnetic encoders are gradually gaining a foothold in the market previously dominated by optical encoders.
