Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.
