It varies in proportion to the strength of the magnetic field. A new Hall effect integrated circuit chip provides increased sensitivity. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The positive temperature coefficient of the sensitivity helps compensate for the negative temperature coefficients of low cost magnets, providing a robust design over a w ide temperature range. NOTE: Products ordered in bulk packaging (plastic bags) may not have perfectly straight leads as a result of normal handling and shipping operations. Please order tape packaging option for applications w ith critical lead straightness requirements.
