HONEYWELL SS494B

The SS494B is a Miniature Ratiometric Linear Sensor features ratiometric output voltage and set by the supply voltage. It varies in proportion to the strength of the magnetic field. A new hall effect integrated circuit chip provides increased temperature stability and sensitivity. Laser trimmed thin film resistor on the chip provide high accuracy and temperature compensation to reduce null and gain shift over-temperature. 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 magnets, providing a robust design over a wide temperature range.
