Solid State Sensors
Miniature Ratiometric Linear
FEATURES
1Small size (.160 ´ .118N)
1Low power consumption - typically 7 mA at 5 VDC
1Single current sinking or current sourcing linear output
1Built-in thin-film resistors - laser trimmed for precise sensitivity and temperature compensation
1Rail-to-rail operation provides more useable signal for higher accuracy
1Operating temperature range of ±40 to +150°C
1Responds to either positive or negative gauss
1Quad Hall sensing element for stable output
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 shift over temperature. The quad Hall sensing element minimizes the effects of mechanical or thermal stress on the output. The positive temperature 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.
SS490 Series
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.
