It’s easy to treat optical encoders as “black boxes” that need minimal consideration before they are installed to translate rotary motion into position or velocity feedback signals for a motion ...

Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...

Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90° in phase. The number of ...

NEW YORK — With NAB Show New York now concluded, ENCO has formally debuted its first closed caption encoder. Introducing DoCaption EN848, available separately or as part of ENCO’s enCaption system. It ...

The electric motor is the fundamental building block of almost all robotic projects but, without some form of feedback, it lacks the precise positional control required for the task. Small servos from ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...

Engineers using an incremental encoder for the first time often have a misunderstanding about what types of signals are provided by an encoder and how to interface an encoder to their application.
