Hall Effect Gear Tooth Sensor With Complementary Output, we deal in is extensively used for several industrial applications. Most commonly, this is suited for determining the shaft, direction and gear speed. Also, it can detect the variations of the magnetic field. Hall Effect Gear Tooth Sensor With Complementary Output makes effective use of the hall element. It is capable enough to measure variation in flux found. The best thing about this sensing solution that it can be implemented with eddy as well as optical current sensors.
