Advancements in computer and component technology have created a genesis in professional audio equipment, allowing studio mixing consoles to offer increased functionality in similar or smaller overall ...

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 ...

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?

Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For industrial applications, incremental encoders (used when only relative position is ...

[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 ...

Numerik Jena’s Kit R rotary optical encoder is ideally suited for those motion feedback applications where installation space is limited. Numerik Jena’s Kit R rotary optical encoder is ideally suited ...

Hirschmann's new gSENS DWG 20 rotary encoder uses optical sensors to break down one revolution of a shaft, of a hoist or slew drive unit, for example, into 8192 increments. The device then converts ...

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.

Download the PDF of this issue, with ideas on how to resolve optical encoder outputs with a PSoC GPIO and interrupts, and how to enhance short-circuit protection with a high-side load driver. This ...
