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 ...

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 ...

Small battery devices need magnetic switches that use power and take up space. These switches detect magnets and help devices run longer.

The new MIS63xx magnetic image sensors are designed and manufactured with MDT's unique TMR technology and intellectual property. They are designed with an array of TMR sensors with a spatial ...

Hprobe, a provider of semiconductor Automated Test Equipment (ATE) for magnetic devices, has demonstrated a new 3D magnetic generator design resulting in magnetic field accuracy of less than 5µT (5 ...

This technical article describes monolithic magnetic sensor integrated circuits (ICs), its operation, and explains how it uses a technique called dynamic quadrature offset cancellation. The offset ...

Infineon has introduced a magnetic sensor for micron-level movement measurement. Called TLI5590-A6W, it has two TMR (tunnel magneto-resistance) Wheatstone bridges inside (see diagram), spaced 500μm ...

Researcher Michael Romalis from Princeton University tests out the in-the-field MEG recording apparatus. (Courtesy: Mark Limes) A portable sensor that can detect tiny biomagnetic signals from the ...

How to navigate the expanding market and avoid missteps where the newest sensors provide more capability than what you’ve ...
