Schlöder CDN-EMCL, EM clamp for immunity tests acc. EN 61000-4-6

 IEC / EN 61000-4-6 

• For the coupling during immunity tests according to IEC/EN 61000-4-6
• Frequency range 10 kHz - 1 GHz
• Suitable for cables up to 20 mm,  for thicker cables up to 35 mm:  use CDN EMCL-35  

EM coupling clamps are always used when the use of coupling / decoupling networks (CDN) does not seem suitable or appropriate. This applies, for example, to unshielded cables consisting of a large number of individual conductors.

With the electromagnetic coupling path, both capacitive and inductive coupling into the cable connected to the test object is achieved. Key facts The EM coupling clamp has a directivity of ≥ 10 dB above 10 MHz, so that a defined impedance between the asymmetrical connection point of the auxiliary / additional equipment and the reference ground plane is no longer required. Above 10 MHz, the behavior of the EM coupling link is therefore similar to that of coupling/  decoupling networks.
