Whether incremental or absolute, magnetic or optical, rotary encoders track motor shaft rotation to generate digital position and motion information. Their use proliferates in industrial and ...

Optical encoders are critical components in systems with rotating shafts or parts. Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals.

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 ...

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?

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.

In any application using motors for automation, there is a need to ensure accurate control of the motor. To make this possible, the position and speed of the rotor in the motor, which is usually ...

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 ...
