OPtical Magnetic Encoders！

The heart of an encoder is the way that it provides information – that’s the encoder engine. An encoder engine takes the positional and speed information and then supplies the signal that is sent to the application.

The engine type is categorized by the method that the control information is determined. There are two major categories:

• Optical encoder engines, both masked and phased array
• Magnetic encoder engine

The differences in the way that a magnetic encoder and an optical encoder gather information lead to performance differences in different operating environments. Understanding how an optical encoder and magnetic encoder work can help determine what kind of optical encoder is best suited to your application.
