Magnetic Sensors for 5 Hz-1 MHz

These calibrated single-axis coil sensors are accurate cost-effective tools for measuring magnetic fields from 5 Hz to 1 MHz. They respond to AC or RF magnetic fields parallel to the coil axis, and produce an analog output voltage which is accurately calibrated to the magnetic field strength. You display the sensor output voltage on your own instrument (AC or RF voltmeter, multimeter, oscilloscope, or spectrum analyzer with high input impedance).

No battery or power supply is needed for the sensors. These are easy, accurate, affordable sensors for magnetic field measurement, test and EMC / EMI / RFI troubleshooting. The frequency of the sensor output voltage is the same as the frequency of the magnetic field. These sensors do not measure static or DC magnetic fields from magnets, magnetized metal, nor the earth's magnetic field. The frequency range listed in the table below has output voltage at least 0.7 mV per mG from the sensor. The sensors can be used at other frequencies but the output voltage will be lower, as seen in the graph.
