FEATUR
*  all size  (.160 x .118 in)
*  Power consumption of 7 mA
  at 5 VDC for energy
  efficiency
*  Single current sinking or
  current sourcing output
*  Linear output for circuit
  dign flexibility
*  Built-in thin film ristors are
   laser trimmed for precise
  sensitivity and temperature              The SS490 Seri MRL (Miniature Ratiometric Linear) sensors are all,
  compensation                          versatile linear Hall effe devic which are operated by the magnetic field
*  Rail-to-rail operation               from a permanent magnet or an eleromagnet. The ratiometric output
   provid more useable                voltage is set by the supply voltage and vari in proportion to the strength
  signal for higher accuracy            of the magnetic field.
*  Temperature range of -40°C              The integrated circuitry provid increased temperature stability and
  to +150°C                             sensitivity. Laser trimmed thin film ristors provide high accuracy (null to &plun;
*  Rponds to either positive          3%, sensitivity up to &plun;3%) and temperature compensation. The linear
  or negative gauss                     position sensors have an operating temperature range of -40C to +150°C,
*  Quad Hall sensing element            appropriate for industrial and automotive environments. They rpond to
  for stable output                     either positive or negative gauss, monitoring either or both magnetic pol.
                                        The quad Hall sensing element minimiz the effes of mechanical or
TICAL APPLICATIONS                    thermal strs on the output. The positive temperature coefficient of the
*   Current sensing                     sensitivity (+0.02%/°C tical) helps compensate for the negative
*   Motor control                       temperature coefficients of low cost magnets, providing a robust dign
*   Position sensing                    over a wide temperature range. Rail-to-rail operation (over full voltage
*   Magnetic code reading               range) provid a more usable signal for higher accuracy.
*   Rotary encoder                         The recent extension to the produ line, the SS490B Seri, offers cost-
*   Ferrous metal deteor              effeive MRL sensing solutions with slightly wider specifications than the
*  Vibration sensing                    SS490 high-performance produs. Like the SS490 Seri, the SS490B
*   Liquid level sensing                has a tical sinking or sourcing output of 1.5 mA continuous, us 7 mA of
*  Weight sensing                       supply current at 5.0 volts and 25C, and provid prediable performance
                                        over the full temperature range. The SS490B Seri sensors have wider
    WARNING                             null and sensitivity toleranc and a wider drift over temperature.
PERSONAL INJURY                            The SS490B Seri sensors are a new lower cost produ line extension.
*  DO T USE the                     They complement the SS490 Seri of all size, high accuracy and high
   produs as safety or                performance miniature linear produs.
