Example Allegro GMR automotive rotational sensors (right) are A19350 for sensing ring magnets, or ATS19480 and ATS19580 for plain ferromagnetic targets – the latter includes a direction output. Inside ...

Industry-leading air gap enables increased reliability, efficiency, and design flexibility Allegro’s new GMR gear tooth speed sensor with industry-leading air gap, ATS19480, gives transmission ...

Allegro Microsystems is advocating GMR (giant magneto-resistive) -effect sensors, instead of Hall-effect ones, for automotive rotary wheel-position sensing. The company, which makes both Hall-effect ...

Allegro MicroSystems has released the ATS19580, said to be the first fully-integrated, back-biased giant magneto-resistive (GMR) transmission speed and direction sensor. Achieving the highest level of ...

Allegro MicroSystems has introduced a state-of-the-art giant magnetoresistance (GMR) speed sensor that measures the rotation of ferromagnetic gears. The ATS19480 speed sensor IC provides a ...

Cutting-edge GMR technology gives automakers best-in-class performance and efficiency ATS16951 & ATS16351: Allegro's Revolutionary New GMR Camshaft and Crankshaft Sensors Cutting-edge GMR ...

Giant Magnetoresistive (GMR) materials vary electrical resistance according to changes in an applied magnetic field. The interaction generates electrical signals that can be read as data. Stanford ...

A magnetic resonance (MR) sensor testing platform was used for pilot device performance testing. GMR ratios were observed to reach 5.6%, matching conventional antiferromagnetic layer-based GMR ...
