Brochure: Revolutionary GMR Cam/Crankshaft Sensors
The new Allegro ATS16951 crankshaft and ATS16351 camshaft sensors leverage giant-magnetoresistance (GMR) technology to create an ideal pairing for hybrid vehicle engines, two-wheelers, off-road vehicles, and other application designs that require extended air-gap performance.
Application Note
Mechanical Shift of Switch Point
AN296243 - The mechanical shift of switch point is a specification that provides detail necessary to predict the location of an output edge with respect to the integrated circuit (IC) package and the target feature. This application note illustrates how to apply this specification.
Application Note
GMR Crankshaft Target Design Guidelines
AN296198 - This application note offers guidelines for designing an optimal target for crankshaft applications.
Application Note
Fundamental Properties of Speed Sensors
The aim of this application note is to provide a solid foundation for understanding and comparing the fundamental properties of speed sensors that are valid not only for Allegro products but for speed sensors in general.
