Description
The SS490 Series MRL (Miniature Ratiometric Linear) sensors are versatile linear
Hall ef f ect devices operated by the magnetic field from a permanent magnet or an
electromagnet. The ratiometric output voltage is set by the supply voltage. It varies
in proportion to the strength of the magnetic field.
The integrated circuitry provides increased temperature stability and sensitivity.
Laser trimmed thin film resistors on the chip provide high accuracy (null to 3%,
sensitivity up to 3%) and temperature compensation. The positive temperature
coefficient of the sensitivity (+0.02 %/ C typical) compensates for the negative
temperature coefficients of low cost magnets.
The SS490B Series sensors offer cost-effective MRL sensing w ith slightly w ider
specifications than the SS490 products. The SS490B has a typical sinking or
sourcing output of 1.5 mA continuous, uses seven mA of supply current at 5.0
volts at 25 C, for predictable performance over the full temperature range. SS490B
Series sensors have w ider null and sensitivity tolerances and a w ider drift over
temperature.
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.
