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 ...

• The new mantra of position encoding is low-current drain. • Capacitive encoding is a way to realize low-power consumption without giving up resolution or accuracy, even at relatively low speeds.

The absolute encoder determines the unique position of the value at every point of rotation by generating distinctive bit configurations. It retains its true position of the rotating shaft throughout ...

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 ...
