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 ...

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 ...

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 ...

LAS VEGAS--(BUSINESS WIRE)--At the International Consumer Electronics Show (CES) 2015, Correlated Magnetics Research (CMR) demonstrated a novel approach to magnet sensor controls for consumer products ...

This file type includes high-resolution graphics and schematics when applicable. In the seemingly endless quest for higher motor performance and improved system cost efficiencies, motor manufacturers ...

Researchers used an ultrathin graphene 'sandwich' to create a tiny magnetic field sensor that can operate over a greater temperature range than previous sensors, while also detecting miniscule changes ...

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 ...

Researchers demonstrated a magnet-based system that can track the location of muscles and could be used to help people control prosthetic limbs and other wearable robotic devices. Using a simple set ...

Chinese scientists have developed a new gravity-based detector that could be used to detect ...

The magnetic sensor market is expected to reach $3.7 billion in 2029, with an estimated 4% CAGR from 2023 to 2029, says Yole Developpement. Allegro Microsystems leads in revenue, TDK leads in volume.
