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 ...

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 ...

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 ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

The new magnetic sensor is inexpensive to make, works on minimal power and is 20 times more sensitive than many traditional sensors. A team of Brown University physicists has developed a new type of ...

Quantum mechanics states that electrons have two stable spins—up and down. With the advent of nanoscale fabrication methods, device companies are harnessing this knowledge to create devices. The ...

While most sensors that surround us and make modern technology possible are well-known and understood, magnetic sensors used in magnetometers are often overlooked or misunderstood, even though they’re ...
