;9. B = Magnetic flux density
 
1mT=10Gauss
 
Positive (+) polarity flux is defined as the magnetic flux from south pole which is direct toward to the branded face of the sensor.
 
After applying power supply, it takes one cycle of period (T
P
) to become definite output.
 
Radiation hardiness is not designed.
