The rapid spread of electromagnetic radiation and the ever greater sensitivity of modern electronic components mean cable glands play an important role in a system’s screening concept. In everyday production scenarios, standard cable entries without sufficient EMC protection are still frequently used, even though they pose a significant safety risk.
You can eliminate this risk right from the outset – with EMC solutions from PFLITSCH. With its UNI Dicht and blueglobe series, PFLITSCH offers a scaled range of EMC product solutions for EMC applications up to category 8.2.
High screening attenuation values give your system reliable EMC screening
High current-carrying capacity for reliable discharge on enclosure
Reliable 360° cable shield contact
Suitable for a broad range of temperatures
Outstanding all-round properties such as tightness and strain relief
Time- and cost-saving installation
There are hardly any limitations on the use of EMC cable glands. That’s why our solutions are designed for every application, no matter how unusual. Two factors are decisive for the quality and the effectiveness of an EMC cable gland: the attenuation values and the current-carrying capacity.
Outstanding attenuation values are required wherever interference signals resulting from electromagnetic coupling can impair the transmission of sensitive data and such data must be protected, e.g. in the fields of measurement and radar technology, drivetrain and control technology, and telecommunications.
The electrical screening effect of EMC cable glands is essentially determined by the following properties:
Conductivity of the material surfaces
Transitional impedance between cable shield and/or contact element
Transitional impedance between contact element and/or cable gland body
Transitional impedance between cable gland body and/or housing
A high current-carrying capacity is necessary if high current levels flow through the shielding braid of the cable and they are to be reliably discharged at the machine enclosure. Cable glands without sufficient current-carrying capacity can easily overheat and become damaged, which then also means that the screening effect is no longer guaranteed. Particularly in the field of e-mobility – especially in high-voltage vehicle systems – the current-carrying capacity is extremely important. With PFLITSCH EMC cable glands, which have been specially developed for the electric mobility industry, you are always on the safe side.
The effort required to install an EMC cable gland depends on the structure of the component and requires a careful approach. PFLITSCH products are user-friendly and guaranteed to be quick and easy to install. The EMC cable glands in the blueglobe range are particularly simple to install. The cable sheathing only needs to be stripped at the contact point. Once the braiding has been stripped, the cable can be easily pushed through the cable gland. The triangle spring immediately wraps itself securely around the braided screen. The design of the TRI spring prevents it from becoming caught in the braiding during assembly or disassembly.

In rail vehicles, components such as cable glands must have a whole range of sophisticated properties. These include fire protection suitability, tightness, vibration resistance, mechanical protection (e.g. from stone impact) and weather resistance. Furthermore, reliable screening attenuation is essential for certain applications. This is provided by safe EMC solutions from PFLITSCH: For example, the UNI EMC Dicht fire protection cable gland is used in rail traction motors in the driven rotary points in the underfloor area. And the blueglobe TRI fire protection cable gland is used for voltage and frequency converters in the carriage roof or underfloor area for the electrical supply of components and power and data cable entry. However, our EMC solutions can also make an important contribution to safe mobility in the provision of phone and internet mobile data on trains and the use of modern passenger information systems.
Automatic production processes are becoming increasingly sensitive to electromagnetic interference. The reason: the progressive automation, digitalisation and miniaturisation of components as well as the increasing use of electronic devices, which means that EMC security is therefore becoming more and more important. If an electromagnetic disturbance occurs and interrupts operations, the damage is incalculable. The solution: Due to their high screening attenuation, PFLITSCH EMC cable glands enable electromagnetic interferences from the cable shield to be reliably discharged from equipment enclosures and thus kept away from the production process.
Wind farms are subject to continual checks and supervision. Their data and processes are all constantly recorded, collected and distributed. Not only do large volumes of data need to be transmitted, they also need to cover long distances. Up to 160 m between the nacelle and the base of the tower need to be bridged. If data cables are used, the signals can be impaired by electromagnetic interference. To solve this problem, PFLITSCH has developed EMC cable glands with bending protection suitable for data connectors in order to meet all the data communication requirements.
PFLITSCH cable glands feature a high level of screening attenuation. Screening attenuation is a measure of shield quality in terms of electromagnetic compatibility. This property also plays a key role when selecting the right EMC cable gland. PFLITSCH has developed a measuring method for determining the quality of the screening effect by calculating the frequency-dependent voltage drop across the cable gland. Our KoKeT (Koaxial Kelvin Tube) procedure allows measurements in accordance with IEC 62153-4-10 on screened cable glands up to size M85.
For international use, the two PFLITSCH cable glands meet international standards that include VDE, UL, CSA, DNV and EAC. They also safely and reliably meet the worldwide ATEX standards.
