This application note presents some of the fundamental information about Hall-Effect sensors. It also presents the basics of magnetics, and the added value of programmable sensors and sensor interface ...

A team of researchers have developed the world's thinnest and lightest magnetic sensor matrix sheet system that visualizes the two-dimensional distribution of magnetism on various surfaces, with a ...

Contrary to the implications of their diminutive name, when it comes to supplying the global electronics market, Littelfuse is a name that’s about as large as names get in terms of outright presence.

A new scanning microscope developed at Brown University can uncover defects in the smallest and most complex integrated circuits at a resolution 1,000 times greater than current technology. The ...

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 ...

This energy management interface is the "brain" of a self-powered, battery-free sensor that can harvest the energy it needs to operate from the magnetic field generated in the open air around a wire.

Magnetic sensors detect moving ferrous metal. The simplest magnetic sensor consists of a wire coiled around a permanent magnet. A ferrous object approaching the sensor changes magnetic flux through ...

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 ...

Fig.1: Imperceptible magnetic sensor matrix system. (Image: Osaka University) (click on image to enlarge) Conventional magnetic sensor circuits consist of silicon-based hard electronic elements ...
