About Magnetic Sensors:

A magnetic sensor is a device that detects magnetic fields. When selecting a magnetic sensor, consider the following technical specifications:

• Sensitivity or Transfer: (V/T or V/A·m, A/T, Hz/T…) - How much the output changes for a given change in magnetic field.
• Absolute Accuracy: The overall accuracy of the sensor’s readings.
• Power Spectral Noise Density: (in T²/Hz) - The noise level of the sensor.
• Bandwidth: The range of frequencies the sensor can accurately measure.
• Operating Temperature: The temperature range in which the sensor functions correctly.
• Full Scale: The maximum range of magnetic field the sensor can measure.
• Dynamic Range: (dB) - The ratio between the largest and smallest magnetic fields the sensor can measure.
• Slew Rate: (T/s) - How quickly the sensor can respond to changes in the magnetic field.
• Distortion vs. Frequency: (%) - How much the sensor distorts the signal at different frequencies.
• Linearity Error: (%FS) - The deviation from a perfectly linear response across the full scale.
• Resolution: The smallest change in magnetic field the sensor can detect.
