EMC, or electromagnetic compatibility, is the ability of the equipment, cables, or systems to function satisfactorily in their electromagnetic environment without introducing intolerable electromagnetic disturbances to any other equipment in that environment.
With the increased use of variable speed drives (VSD), instrumentation and control, wireless data acquisition and communication in industries, the reliance on EMC cables and enclosures to maintain signal and power integrity has become increasingly more important.
Although cable glands do not emit electromagnetic interference (EMI) they are connected to cables that could form part of an installation that could emit or be susceptible to electromagnetic interferences.
Because electromagnetic emissions can be affected by the quality of the connection through the gland to the cable armour or metallic sheath and to the equipment, CCG has a range of cable glands designed primarily to be used with cables that are EMC compatible.
CCG’s EMC glands have been extensively independently tested according to EN 55011 and EN 55022 EMC standards for Class B radiation emissions.
Most of CCG’s hazardous areas glands are also EMC compatible and these glands are indicated with the symbol.
