Cable Glands - Electromagnetic Compatibility EMC 

Pflitsch EMC Cable Glands Up To Cat. 7A

 

Pflitsch offers a graduated selection of EMC capabilities in its UNI Dicht and blueglobe cable glands for use in EMC applications up to Cat. 7A.

Pflitsch electromagnetic compatibility (EMC) specialist Günther Quednau says the company’s Blueglobe TRI is the standard-setting cable gland in terms of EMC performance, with the seal and EMC screening separated from one another giving the highest damping values – usually around 80 dB to 100 MHz.

The Pflitsch blueglobe TRI offers an EMC cable gland that sets standards in terms of shield bonding and attenuation values and is also for applications with high-grade double screening.

Even in a frequency range of up to 2.5 GHz, the typical values are at least 50 dB for Pflitsch EMC cable glands. A triangular spring fits around the cable's braided shielding and its design precludes its getting caught in the braiding if the assembly is dismantled.

Pflitsch is the only manufacturer so far to test its EMC cable glands in accordance with IEC 62153-4-10.

Compared to conventional products, the bueglobe EMC cable gland attains maximum clamping ranges, the highest degrees of impermeability up to IP68 and the best strain relief with at the same time gentle sealing that does not irreversibly constrict the cable. 

Electromagnetic Compatibility EMC

The EMC Directive differs from most other CE Marking directives in that its primary requirement is protection of the electromagnetic spectrum rather then safety of the equipment. The vast majority of finished electrical products must comply, whether battery or mains powered. 

The EMC Directive requires that products must not emit unwanted electromagnetic pollution (interference) and must be immune to a normal level of interference.
