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 ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

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 ...

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 ...

This file type includes high resolution graphics and schematics when applicable. The latest generation of 3D magnetic position sensors from ams AG uses a pair of sensor elements (pixels) that make it ...

If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...

A NIMS research team has developed a new experimental method capable of rapidly evaluating numerous material compositions by measuring anomalous Hall resistivity 30 times faster than conventional ...

These IXARC magnetic encoders withstand harsh environments and are modular for maximum versatility. Rotary encoders measure the rotation of machine shafts and report the results to electronic controls ...

Sensors help microprocessor-based systems find their bearings. Where would embedded systems be without them? Sensors provide the windows through which microprocessor-based systems can observe their ...
