All characteristics as measured at 25C 3. ESD PRECAUTIONS MUST BE USED WHEN HANDLING. 4. The RR110 may be operated at lower currents to reduce power consumption, or at higher currents for greater voltage output, as long as the limits noted in the electrical characteristics are not exceeded. 2 7 Magnetic Sensitivity Transfer Curve The magnetic sensitivity transfer curve illustrates the characteristic behavior of an analog TMR sensors resistance change as the strength of an applied magnetic field changes. The magnet approach curve (red line) shows the change in resistance as the strength of an applied magnetic field increases. The magnet recede curve (blue dashed line) shows the change in resistance as the strength of an applied magnetic field decreases. Alternatively, you can think of the resistance going down the red slope as a magnet approaches the sensor, and going up the blue dashed slope as the magnet moves further away from the sensor. 65 8 Sensor Polarity Diagram 60 S 55 N 50 45 HYSTERESIS 3 40 35 30 12 25 20 -150 -100 -500 50 100 150 Field Stre ngth (G) N-Pole Magnet N-Pole Magnet Approaching Sensor Receding from Sensor page 2 Copyright 2018.
