While standard optical encoders have traditionally been used to meet the needs of high-precision sensing and control applications (such as steering-wheel position detection or industrial motion ...

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 ...

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 encoders are typicallyused in positioning systems withservo feedback in which the cost of theencoder usually is of minor importance.Encoders, however, are also usedin user interfaces to encode ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

Heidenhain has expanded its absolute rotary encoder offering with the new RIQ/IQN 425 series. These sturdy, inductive rotary encoders were designed for use in applications in the automation and wind ...
