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 ...

Shaft motion can be tracked by incremental encoders for analysis and use by system controls downstream. Rotational direction is monitored with an encoder disc paired with simple electronics and a dual ...

Rotary encoders provide critical information about a motor shaft’s position, rotational direction, velocity (rpm), and acceleration. They are vital components in motion-control feedback loops used in ...

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 ...

Optical sensors are successfully used for measurement in many areas, such as the position sensing of moving objects or the measurement of distance. The types of sensor elements used in these ...

As products and their components get smaller, the processes to produce them require manufacturers to find new ways to get the job done. For US Digital, which had to deal with tiny Mylar disks for its ...

A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...
