How inductive sensors work Inductive sensors are often used to measure position or velocity, especially in harsh environments. The terminology and technology of inductive position sensors can be confusing for many engineers. In this article, the various types of inductive sensors are explained, how they work, and their respective strengths and weaknesses. Inductive position and [...]
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 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 [...]
