Shaft Encoders - Industrial Equipment For Better Performance

Used in industrial controls, robotics, and other electro-mechanical devices, a rotary encoder or shaft encoders are responsible for converting the angle at which a shaft is positioned into digital code which computers understand. This makes industrial devices perform more precise operations. Examples of these industrial devices would be flood gates, telescopes, and many more.

There are two types of shaft encoders considered in industrial engineering: absolute and incremental. The difference between the two is that absolute encoders create a distinct digital code for one angular shaft of axle, whereas an incremental rotary encoder has two outputs that can be either mechanical or optical.

Some examples of mechanical or optical encoders include:

• Wireless industrial encoders which make use of a real-time wireless interface and available versions include absolute and incremental encoders;
• Express encoders which are encoders that have six different styles;
• Omni encoders that have a resolution which can be programmed anywhere from 1 to 1,000 counts per turn;
• Linear transducers which are cables that provide linear position and speed information;
• Heavy duty encoders for harsh environmental situations, and
• Linear quadrature encoders for motion-control applications.

Before the digital encoders, there were rotational binary encoders that convert angular information into binary code output. Now, the use of digital rotary encoders in the industry is very valuable not only because they ensure the equipment operate with precision, but also because they provide security for industries in running their operations. Timing and the right positioning of axles can affect the way industrial equipment work. The correct timing and alignment of these shafts are a crucial basis for the operations to run smoothly and without any problems.
