The Loop Sensor FESP 5133-F was designed to monitor the generated magnetic fields in radiated susceptibility tests. There is nearly no difference to the FESP 5133-7/41, which was originally designed for MIL-STD461E and previous versions, in which the RF-litz wire type AWG 7/41 was specified. Recent versions of MIL-STD 461 F and G require a resistance between 5 Ω to 10 Ω for the loop sensor instead. This new requirement was met by the use of a suitable RF-litz wire, which provides a resistance of 7.5 Ω for the FESP 5133-F.
