A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Rotary encoders are critical to many applications, even at the hobbyist level. While considering his own rotary encoding needs for upcoming projects, it occurred to [Jan Mrázek] to try making his own ...

This is the first of a two-part series. Part 2 can be found here. Encoders play an integral role in almost every mechanical system that involves motion monitoring or control. There are a variety of ...

Optical encoders and transducers enable users to translate information from one code to another. Optical encoders come in different varieties including rotary encoders and linear encoders. The optical ...

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 ...
