In modern CNC machining, digital encoders play a key role in the form of converting the motion of the machine into actual, readable numbers. While there are numerous varieties such as linear and rotary encoders, they can also be classified on the basis of their mechanism, such as magnetic encoders, optical encoders, inductive encoders and so on. In this blog, Walker Machinery Inc., suppliers of quality digital encoders, will explore the basics, applications and advantages of optical encoders.
What Is An Optical Encoder?
In its essence, an optical encoder performs the same task as any digital encoder. It converts the linear or rotational motion of the machine or tool and translates it into tangible numbers. It mainly uses light to detect the position of a disc or linear scale, which is then converted into an electrical signal that is eventually displayed as a number.
Applications Of Optical Encoders
Optical encoders are primarily used in cases:
- Requiring the highest degree of precision and accuracy
- Understand the positioning of a highly dynamic motion
With these features, optical encoders are best suited for robotic arms that pick and place products, CNC lathes, mills, antennas, and other miscellaneous machine tool operations.
Advantages Of Optical Encoders
The biggest benefits of optical encoders include:
- High degree of accuracy, repeatability, and excellent resolution capabilities
- High level of flexibility, making them perfect for a wide variety of applications
However, before opting for optical encoders, it is key to understand their ideal operating conditions. These digital encodes perform best in clean conditions. That being said, with proper mounting and sealing measures, this requirement can be easily maintained.
