Because optical encoders are functionally similar, “resolution” is often used as a main characteristic for magnetic encoders (a device providing the angle of a magnet attached to a mechanical shaft, under a digital form). Resolution is a key parameter since it indicates the smallest angle that the sensor is capable of resolving. Unfortunately, when comparing products, users may often be misled, as...

This article, second in the series on the MPS MagAlpha magnetic rotary angle sensor family, looks at how the unique SpinaxisTM sensing technology uses digital filtering to achieve the final output resolution, and introduces the MA732 and MA300 versions with programmable filter settings. After sampling the angle via an array of front end Hall elements, the sensor accumulates samples into a modified...

Bipolar stepper motors provide precise position control while operating in an open loop. Industrial automation applications — such as robots, processing, and packaging machinery — and consumer products — such as 3D printers and office equipment — effectively take advantage of the stepper’s inherent position retention. This eliminates the need for convoluted sensor technology, processing power requ...

Real-time feedback, precision, and accuracy are crucial in the dynamic world of robotics. The magnetic position sensor is one element that stands out in assuring these attributes. This article explores the relevance of magnetic position sensors in robotics and their many uses, using examples from the real world to highlight their value. Due to its superior capacity to accurately detect and quan...
