6 Features Of Incremental Rotary Encoders

The 6 main features of incremental rotary encoders include high resolution, positional accuracy, programmability, intrinsic safety, high operating temperature, and excellent vibration and shock rating. Walker Machinery, a leading distributor of digital encoders and DRO systems in Milton, Ontario, explores these 6 features in detail in this blog.

What Are The Main Features Of Incremental Rotary Encoders?

High Resolution

Although not as high as absolute rotary encoders, incremental rotary encoders still have a significantly high resolution. Resolution is defined as the number of measuring units in a single revolution of the shaft. Moreover, the resolution is perfect for their specific applications.

Positional Accuracy

Positional accuracy can be defined as the difference between the measurement or value shared by the incremental rotary encoder and the actual physical value. It is measured through a unit called arcseconds or arcminutes. Most incremental rotary encoders have an accuracy of 20 arcminutes or more.

Programmability

Programmability is a great measure of the overall flexibility of the incremental encoder. For instance, whether their resolution can be altered for specific applications. This is a major feature to look out for in rotary encoders due to their ease of use and cost-effectiveness.

Intrinsic Safety

Some incremental rotary encoders have intrinsic safety features and ratings for operations in hazardous environments such as oil extraction, gas production, and chemical manufacturing. This is important in order to not give out spark that may ignite hazardous materials nearby.

High Operating Temperature

Aside from safety, some incremental rotary encoders also feature the capability to handle tough conditions such as high operating temperatures, high humidity and moisture ingress. To maintain accuracy, these encoders account for thermal expansion and contraction.

Excellent Vibration And Shock Rating

Most incremental rotary encoders are also duly rated for vibration and shock resistance. Since most operating environments will feature such conditions, the encoders are required to withstand them without compromising accuracy.

Conclusion

In closing, incremental rotary encoders have one or several of these features, depending on specific applications.
