Because encoders limit the number of controls required to increase functionality, they reduce the real estate needed in a given piece of equipment and, in turn, can reduce the point of focus or ...

Vying for position as a contactless alternative to mechanical rotary switches, the AS5030 and AS5130 8-bit absolute magnetic rotary encoders integrate push button and low-power mode features. Both ...

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 ...

Elma Electronic Inc. now offers a miniature rotary encoder that includes an illuminated 8+1 joystick, enabling seamless, accurate control using just one finger. Elma Electronic Inc. now offers a ...

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

Anders has introduced a family of rotary switches that have a circular colour TFT-LCD in the middle, as well as a push button function. Available with 1.3, 2.1 or 2.47inch circular displays, the knobs ...

When you need to make very tiny measurements, even noise in closed relays can throw you off. [Marco] was able to observe this effect and wanted to build a switch that didn’t have this problem. He ...

This file type includes high resolution graphics and schematics when applicable. Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For ...

Not every project has to be complicated– reinventing the wheel has its place, but sometimes you find a module or two that does exactly what you want, and the project is more than halfway done. That ...
