Description
The SS490 Series MRL (Miniature Ratiometric Linear) sensors are versatile linear Hall effect 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 25C, 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.
