An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

That level of resolution is ideal for commutation, high-speed motor control, position/velocity control, and replacement of potentiometers and optical encoders. It’s a low-power 3.3-V (or 5-V) device, ...

Gear Potentiometers are also called Thumbwheel Potentiometers. Let’s investigate them. There are many varieties of compact gear potentiometers available. Most of them are single and dual – this time ...
