5 Instances Where Optical Encoders Are An Ideal Choice

Digital encoders are vital for proper positioning accuracy in CNC equipment. Different types of digital encoders are employed based on of conditions and applications. One popular form of encoders is optical encoders, which use light to achieve highly accurate positioning. But it is not the perfect choice for all situations. Read on to understand when it is best suited to use these encoders.

When To Opt For Optical Encoders?

Applications Where High Precision Is Required

In applications where a high level of precision is required such as machine tools, robotics, or medical devices, rotary or optical linear encoders are the ideal choice. This is because they can accurately measure even the slightest of movement or rotations, and in these applications, there is little to no margin for error.

Dust-Free Conditions

Since optical encoders rely heavily on light to detect movement, it is very important to keep them clean. This is why they are best suited for highly sterilized environments, where contaminants such as dust and debris are absent. This allows them to function at their highest capacity.

High Resolutions Applications

In conditions where high resolution is desirable, optical encoders are the best bet. The high number of pulses per revolution allows these digital encoders to detect position movement with a very high degree of accuracy.

Environments With Strong Magnetic Fields

In applications where strong magnetic fields are at play, magnetic encoders are obviously ruled out. Fortunately, optical linear encoders and their rotary counterparts remain unaffected in these conditions, making them an excellent replacement.

Long Service Life Is Required

In sterilized environments, optical encoders can function at the highest level for a very long time. This is because they operate purely on light. Therefore, they don’t have a sensing mechanism that requires contact with the tool. This rules out major wear and tear. Thus, apart from a malfunction, a proper optical encoder can have a very long and viable lifespan.
