I wrote a bit of VHDL for generating inc/dec pulses from quadrature rotary encoders like the CTS Electrocomponents ones I bought from Digikey for a project I worked on recently. This debounce circuit ...

The rotary encoder family from austriamicrosystems has two new members, the AS5030 and the AS5130, which are 8-bit absolute magnetic encoder ICs that feature pushbutton and low-power-mode capabilities ...

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 ...

My previous blog Encoders Know All the Angles introduced encoders that provide information about rotary positions. A diagram illustrated the phase relationship of signals from an incremental encoder.

Elma’s E18 rotary encoder comes in through-hole and surface-mount versions in the 14.4 x 11.4 x 6.5mm body size. Rotational life is up to 150,000 revolutions, according to distributor Foremost, which ...

Exl 1100 Series rotary encoders now come in versions whose mating dimensions are the same as those of common resolvers The Exl 1100 Series rotary encoders now come in versions whose mating dimensions ...

An absolute optical rotary encoder from Baumer Electric Ltd., Southington, Conn. (www.baumerelectric.com), features 36-bit resolution and measures 262,144 pulses/rev over 262,144 revolutions. That ...

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 ...

HEIDENHAIN is meeting the market demand for high-speed, high-resolution modular rotary encoders for motion feedback with the launch of the ERO 2000 series encoder. The encoders’ special properties are ...

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?

[Long Haired Hacker] has undertaken a high-resolution 3D printer build. He got his hands on some motors to drive the build platform but it doesn’t have a built-in encoder. He knows that optical ...
