Sensor, Hall Effect, Ratiometric, Linear - 

The SS495A is a high performance, miniature ratiometric linear (MRL) solid state hall effect sensor in 3 pin TO-92 package. This small and versatile sensor is operated by magnetic field from permanent magnet or an electromagnet. The ratiometric output voltage is set by supply voltage and varies in proportion to strength of magnetic field. The integrated circuitry provides increased temperature stability and sensitivity. Laser trimmed thin film resistors provide high accuracy (null to ±3%, sensitivity up to ±3%) and temperature compensation. The quad hall sensing element minimizes the effects of mechanical or thermal stress on output. The positive temperature coefficient of sensitivity (+0.02%/°C typical) helps compensate for negative temperature coefficients of low cost magnets providing robust design over wide temperature range.
