The handheld coil FESP 5133-1330 was designed for immunity testing against magnetic fields up to approx. 20 kHz. The coil has 225 turns of Cu-wire on 15 layers. There are spacers to provide a constant distance of 50 mm between coil center and EuT-surface. The generated magnetic fieldstrength is direct proportional to the coil current. Typical applications are Immunity Tests according to the Measuring Method SF 01 G acc. to VG 95377 standard.
