Most of the hacks we see around these parts have to do with taking existing components and cobbling them together in interesting new ways. It’s less often that we see existing components gutted and ...

Leeser holds up a magnetic encoder (left) and an optical encoder. Even though optical absolute encoders represent the bulk of sales for Posital, a division of the industrial group Fraba, its CEO, ...

It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...

This is an incremental rotary encoder that uses contactless magnetic sensing to detect rotational speed and direction. The two Hall Effect sensors measure the 66-pole ring magnet and output two ...

SICK has launched the DUS60 incremental encoder and DUV60 measuring wheel encoder with DIP switch programmability to provide users with a versatile and economical user-configurable motion control ...

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 ...

Linear encoders sense and digitize linear position and movement. A linear encoder is a sensor linked to a scale. The sensor reads the scale and converts position into an analog or digital signal that ...

[Pete] needed a rotary encoder for one of his project so he set out to build his own. As the name implies, a rotary encoder measures rotation by encoding “steps” into electrical signals which can be ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

We develop a methodology for absolute encoding of spherical motion. This is accomplished by painting the surface of a moving ball in two colors and sensing the color at a finite set of points. We show ...
