Absolute encoders are nowadays preferred in numerous applications because of their precise rotation settings. In case of some electricity supply problems, the absolute encoder does not lose its registered initial place and location. Absolute shaft encoders have distinctive positioning and can prolong the operational circle as soon as the power is turned on.

An absolute encoder can be multi-turn or single-turn. The multi-turn encoder is better for applications requiring lengthy positioning and complex positioning requirements. The single-turn option is suited for short travel applications since position verification is necessary with a single encoder shaft turn.

Why Are Absolute Shaft Encoders Preferred?

The absolute rotary encoder has its primary purpose in implementing a specific sensing principle. Generally, such an encoder will be more complex and used in much more complex systems. The main advantages that have to be mentioned when talking about absolute rotary encoders are: the position of an encoder is saved, so in case of a power outage, it will still be in the memory of the application implemented in the same way as was programmed.

Various interface options are now available, including Ethernet and analog. Absolute encoders typically include different advantageous functions like presets, scaling, and speed. Both multi-turn and single-turn options are available.

Application Of Absolute Encoders

The absolute encoders are preferred in some specific situations. Based on the technical demands provided by the customer’s experts, producers like Rozum manufacture unique mechanisms following the provided technical specifications. Robotics and its components is a rapidly expanding area that is covering numerous

sectors.

  • For example, we often see robotic arms utilized in manufacturing for paint spraying, welding, assembly, and countless other tasks.
  • Robotics are also ubiquitous in healthcare. There are remote surgeries that are implemented with the help of robotic arms.
  • Even home-assistance robots are a situation in which absolute encoders are necessary.

The number of systems that are now going digital is quickly growing. We also have a lower gap between the absolute and incremental encoders. This is why the number of applications in which absolute encoders can be used is multiplying. This ranges from camera gimbals and automated property gates to factory robotic automation. Nowadays, they have become part of different mechanical actuators as well.

Conclusions

Absolute encoders are mandatory for various modern engineering projects because of their advantages over other options. Their prices are relatively high, especially compared to simple non-industrial models, but the reliability, efficiency, and lifetime value are evident. Experts expect to see an increased use of these encoders in the following year.
