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 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.

straight leads as a result of normal handling and shipping operations. Please order

tape packaging option for applications w ith critical lead straightness requirements.
