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 S490B Series sensors offer cost-effective MRL sensing with slightly wider 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 wider null and sensitivity tolerances and a wider 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 with critical lead straightness requirements.Product SpecificationsProduct TypeMiniature Hall-Effect Linear Position Sensor ICPackage Quantity/TypeAvailable in 1,000/BagPackage TypeRadial Lead ICSupply Voltage4.5 Vdc to 10.5 VdcOutput TypeSink/SourceTermination TypePC BoardMagnetic Actuation TypeRatiometricOperating Temperature-40 °C to 150 °C [-40 °F to 302 °F]Storage Temperature-55 °C to 165 °C [-67 °F to 329 °F]Output Voltage0.2 Vdc to (Vs- 0.2 Vdc) typ., 0.4 Vdc to (Vs- 0.4 Vdc) min.Linearity (% of Span)-1.0% typ.Output Voltage Span (min.)0.4 Vdc to (Vs- 0.4 Vdc)AvailabilityGlobalSupply Current8.7 mA @ 5 VdcSensitivity2.500 mV ± 0.200 mV/GOutput Voltage Swing (Negative G)0.4 VdcOutput Voltage Swing (Positive G)Vs- 0.4 VdcTemperature_Error_25_Null_Shift_2 ± 0.064Temperature_Error_25 Sensitivity_1-0.02 min., 0.08 max.Output_Current_Typical_Source_451.5 mAOutput_Current_Minimum_Source_451 mAOutput_Current_Minimum_Sink_450.6 mAOutput_Current_Minimum_Sink_51 mAMagnetic Range (typ.)-84 mT to 84 mT [-840 G to 840 G]Magnetic Range (min.)-75 mT to 75 mT [-750 G to 750 G]Output Voltage Span (typ.)0.2 Vdc to (Vs- 0.2 Vdc)Null Output2.50 Vdc ± 0.150 VdcResponse Time3 µsSeries NameSS490
