Both incremental encoders and absolute encoders provide various benefits to their users in many industrial areas. Although there are certain common benefits provided by both encoder types; It differs from each other in terms of the benefits it offers. Therefore, when choosing the encoder, the differences between absolute and incremental encoders should be well known, and the most suitable one should be chosen for the application area to be used. In this direction, as ILX Engineering, we will discuss this issue in the blog post we prepared this week. After giving general information about incremental encoders and absolute encoders, we will list the differences of these two encoder types. We hope it will be a useful article for those who want to get information about the differences between incremental and absolute encoder, we wish you a good reading.
Incremental encoders are a type of encoder that is frequently used in position information and counting processes by generating a continuous square signal for the rotating shaft. Incremental encoders, which differ from absolute encoders in many ways, are electromechanical devices that provide feedback. Incremental encoders that enable position control have many uses in industry, especially industrial robots, CNC machines, medical devices and packaging machines.
Information About Absolute Encoder
Absolute encoders have a different internal structure and operating style compared to classical encoders. It is a type of encoder that provides position information in different formations instead of pulse information. It can mechanically protect position information against power failure or other technical malfunctions. Absolute encoders, which produce a different code for each position, do not seek an absolute reset point when powered up. Absolute encoders offer advantages such as permanent memory, security, solutions against electrical interference and noise in the areas where they are used. The most important feature that stands out is that it can maintain its position even in power cuts.
After giving a general overview of the absolute and incremental encoder types, we can start to list the differences between these two encoder types:
The biggest difference between incremental encoders and absolute encoders is their position from the moment they are switched on. Incremental encoders accept their position as 0 from the moment they are powered on. Absolute encoders, on the other hand, remember their position thanks to their permanent memory feature and continue from the last point when they are operated.
Absolute encoders tend to be more expensive than incremental encoders.
Absolute encoders have a different internal structure and operating system than classical encoders.
While incremental encoders give pulse signal; Absolute encoders give a binary value set.
Absolute encoders cannot exceed the range of the number of turns. In incremental encoders, the number of transformations is not limited.
There is also a difference between the code discs of absolute and incremental encoders.
In the blog post we prepared as ILX Engineering, we mentioned the differences between absolute and incremental encoders. In our article, we first gave general information about these two encoder types and then listed the main differences between them.
