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 ...

Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

Motion-control or industrial automation system designers who need to measure the rotation of shafts or other mechanical components can typically choose from two types of rotary encoders. Encoders ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

With six channels, the RCM1 rotary optical encoder eliminates Hall-Effect sensors inside of motors. The 2.1-inch diameter encoder simplifies assembly and eliminates Hall sensor alignment, increasing ...

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.

SCHAUMBURG, IL--(Marketwired - June 16, 2015) - NUMERIK JENA's Kit R rotary optical encoder is ideally suited for those motion feedback applications where installation space is limited. The scanning ...
