Schwarzbeck Handheld Coil FESP 5133


The magnetic, handheld coil FESP 5133 was designed to generate defined magnetic field strength in the audio frequency range up to 100 kHz. The main application is immunity testing against magnetic fields according to e.g. (of professional studio equipment acc. to EN 55103), MIL-STD 461, VG 95377 part 13) and many others). Depending on the current source characteristics magnetic fields up to 1000 A/m can be generated for a short time.
