A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...

Get the most out of brushless dc motors by specifying optical encoders. They measure finer movements than hall sensors, because their operation doesn't rely on motor phases. Brushless dc (BLDC) motors ...

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 encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...
