Pflitsch EMC cable glands
13 February 2012
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.

Even in a frequency range of up to 2.5 GHz, the typical values are at least 50 dB.
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. Furthermore, Pflitsch is the only manufacturer so far to test its EMC cable glands in accordance with IEC 62153-4-10.
Also, according to Ouednau, by playing its part in the development of the KoKeT procedure, the company has shown itself to be well ahead of other players in the industry. KoKeT is an Anglo-German acronym for Koaxial (coaxial measuring device), Kelvin (four-terminal sensing) and Tube (tubular construction). The KoKeT procedure is optimised for the testing of cable glands and allows the use of older and simpler high-frequency measuring devices, often already in a company's instrument cabinet. The procedure can also be used to test products in interference-compromised environments (non-screened rooms). KoKeT has been incorporated into IEC 62153-4-10 and has been officially proved to be fully compatible with the standard.
