Standard convention for representing the direction of magnetic field strength and flux density by positive and negative signs is as follows:

Magnetic field and flux density from South pole magnet to the part marking surface of the sensor is positive. Magnetic field and flux density from

the North pole magnet to the part marking surface is negative field. The positive and negative signs in below graph follow this standard

convention. The positive and negative signs in the table below follow this standard convention.

Notes:

9. Maximum and minimum parameter values over operating temperature range are not tested in production, they are guaranteed by design,

characterization and process control. The magnetic characteristics may vary with supply voltage, operating temperature and after soldering.

10. Typical and minimum hysteresis is guaranteed by design and characterization.
