A novel magnetic sensor for the first time detects tiny fluctuations in a small magnetic field -- even when there is a strong magnet right beside it. The sensor can thus be utilized even in places ...

A Hall-effect sensor is a transducer that converts a magnetic field directly into a usable electrical voltage. It enables ...

A new family of permanent magnet linear displacement (PLCD) sensors is based on the electromagnetic induction principle, which places a primary winding around a soft ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Magnets are found in motors, speakers, sensors, and countless everyday devices. This video explains how magnetic fields work ...

The magnetic sensor market valuation is poised to reach USD 9 billion by 2032, as reported in a research study by Global Market Insights Inc. Robotics and automation are rapidly emerging as prominent ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

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 ...

A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use of spin defects in hexagonal boron nitride (hBN) as powerful, ...

Tired of encoders that take space and need maintenance? A sensor design makes motion systems smaller and easier to use.
