Looking For Industrial Encoders?
Monday, December 3, 2018

Industrial encoders come in two major form types; Absolute and Incremental. One of the most common questions about these encoders can be answered with a comparison of both which will help you choose the one that best suits your needs. In this blog, we will explain what incremental encoder and absolute encoder are. This will be followed by their functions, which we will be discussing so that you can better assess which of these is better suited for you.

Incremental or Absolute? That is the Question

Incremental and absolute are the two types of industrial encoders that can be used for speed, direction, and position monitoring. The absolute encoder is capable of retaining your position after power loss. This makes it rather reliable in places where there may be a power loss. Incremental would not retain the data as it is not as sophisticated in this regard. After a power loss of any kind, the incremental encoder usually needs a few minutes to recover some of the information. It usually needs to perform a homing sequence to see how far along the increments it had gone before the power was lost.

EncoderIncremental encoders are found to be comparatively less expensive in general. The output by an incremental encoder needed is a square wave. This is basically used for counting, speeds, and directions. Absolute encoders on the other hand are normally used for continuous position and possess other attributes too. These attributes as speed, scaling, preset, and field bus functions; all of which enable it to cover a more in-depth study.

The Absolute Encoder is more advanced and expensive and therefore delivers more functions in comparison. The Incremental models on the other hand deliver most of the same function and are relatively inexpensive but are also less easy to deal with.




What Resolution Does the Application Need?

The incremental encoder records 50,000 pulses per revolution (ppr) speed, on the other hand the absolute encoder can have 16 bits (or 65536 pulses) per revolution. This is a considerable difference and therefore, we can see how advanced a typical absolute encoder is compared to an incremental one. This is an obvious reasoning for why there is such a vast difference in price.

The most important thing to consider here is not the price or the speed but the function you may need this encoder for. One also has to keep in mind the kind of environment that it would be introduced to. The resolution would always depend on the precision of the hardware. Both the electrical and mechanical components would be needed to have top resolution to solve a problem. This could also be used to meet the demands of the process involved.

In certain instances, some controllers cannot handle the frequency response of a high-resolution incremental encoder, so a lower-resolution encoder would have to be chosen. This is where you can consult your local experts on the matter and work out a solution. To book a consultation with the experts on Industrial Encoders, please click here.

Industrial encoders come in two major form types; Absolute and Incremental.


What are Servos?
Wednesday, November 21, 2018
Servo motors are a type of DC motor that allow precise controlling of an angular position and this leads to the motor to switch between angles.
