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 ...

Optical encoders and transducers enable users to translate information from one code to another. Optical encoders come in different varieties including rotary encoders and linear encoders. The optical ...

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 ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...

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 ...
