observed by rotating the front face of the device (see below). This  
The simplest form of magnet that will operate these devices is a  
rotation decreases the effective Hall element-to-element spacing,

provided that the Hall elements are not rotated beyond the width  
are possible. Extensive applications information on magnets and  
of the target.  
Hall-effect sensor ICs is also available in the “Hall-Effect IC  
Applications. It is strongly recommended that an external  
0.01 F bypass capacitor be connected (in close proximity to the  
device) between the supply and ground of the device to
