SS490 Series MRL(Miniature Ratiometric
Linear) sensors have a ratiometric output
voltage, set by the supply voltage. It varies in proportion to the strength of the
magnetic field.
A new Hall effect integrated circuit chip
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 to reduce null and gain shiftovertemperature.
The quad Hallsensingelementminimizes
the effects of mechanical or thermal
stress on the output.The positivetemperature coefficient of the sensitivity
(
+
0.02%/°C typical) helps compensate
for the negative temperature coefficients
of low cost magnets, providing a robust
design over a wide temperature range.
–40 toF125°C (unless otherwise noted)
NOTICE
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 with critical lead straightness requirements.
