Principle and Advantages of Magnetic Encoder

Principle and Advantages of Magnetic Encoder Magnetic encoder detects rotational position information as changes of the magnetic field, converts them into electrical signals, and outputs them. Magnetic encoder with a Shaft-End configuration that combines a magnet magnetized in the radial direction and a Hall element that detects the strength of the horizontal magnetic field is [...]

Off-Axis Configuration Magnetic Encoder

Off-Axis Configuration Magnetic Encoder The advantage of the Off-Axis configuration is that both ends of the rotary shaft can be freed, the encoder as a whole can be made thinner, and hollow through shafts can be supported. The Off-Axis configuration magnetic encoder needs correction to make the Lissajous figure a perfect circle, because the Lissajous [...]
