Product Description

These hall-effect sensors accurately track extremely small changes in magnetic flux density- Changes generally too small to operate hall-effect switches. As motion detectors, gear tooth sensors, and proximity detectors, they are magnetically driven mirrors of mechanical events. As sensitive monitors of electromagnets, they can effectively measure a system's performance with negligible system loading while providing isolation from contaminated and electrically noisy environments. Each hall-effect integrated circuit includes a hall sensing element, linear amplifier, and emitter-follower output stage. Problems associated with handling tiny analog signals are minimized by having the hall cell and amplifier on a single chip. Three package styles provide a magnetically optimized package for most applications.

Note 1: Unit is mV / mT, the sensor sensitivity is a reference only when it's in the linear region. When the strength of measured magnetic field exceeds the linear range, the magnetic field strength and voltage values can't be given.
Note 2: Quiescent output voltage is at room temperature, when Vcc = 5V measured.
Note 3: Unit is Millitesla, 1 mT=10 Gs. In actual use, we suggest that the working magnetic field of sensor should smaller than the range given in the table.
Note 4: Re M-type (SOT23-3L) products, its working magnetic field is subject to N pole.
