The application of encoder！

Encoders provide feedback on motion in a variety of applications, such as placing a patient in place on a magnetic resonance imager or filling a beverage at 300 bottles per minute. When choosing encoders, the user must consider some of the most important application features: Is tracking linear or rotary motion? Optical encoders or magnetic encoders? In addition, for successful professional applications, users should also consider the option of incremental encoding Or absolute encoders - Even with the same sensing mechanism, the performance of these two encoders varies greatly. In order to realize a successful application system, you need to know all the relevant characteristics of the above two encoders and make the right choice.

As the name implies, an absolute encoder can record the position of an encoder on an absolute coordinate system while an incremental encoder can output an incremental change of an encoder from a predefined starting position. Incremental encoders require the use of additional electronics (usually PLCs, counters or inverters) for pulse counting and pulse data conversion to speed or motion data, whereas absolute encoders can generate numbers that can identify absolute positions signal. In summary, incremental encoders are generally better suited for simple applications with lower performance, whereas absolute encoders are the best choice for more complex and critical applications - these applications have higher speed and position control requirements . The type of output depends on the application.
