During the eighties, number and sentitivity of electronic devices and systems increased dramatically and little by little the world became aware of "Electro Magnetic Compatibilty" (EMC) related problems. Nowaday, almost everybody talks about this problematic and the related European regulatory.
KABELWERK EUPEN was among the pioneers to develop new technologies to meet the industry's and consumer's requirements for non disturbing and electromagnetically immune systems.
Thanks to many decades of experience with cable manufacturing, combined with a
thorough knowledge in the field of EMC, KABELWERK EUPEN can offer you clear solutions fore some of your EMC problems. |

UNI Dicht EMC cable gland
multiple variations for highly specialised applications
The compact PFLITSCH EMC cable connection type UNI HF with the Iris spring and taper rings are designed for the EMC bonding of screens. The design principle reduces installation time significantly and achieves high damping effects. When the pressure screw is tightened, the Iris spring is guided by two tapers until it encircles the cable screen and contacts it securely through 360°.
The advantages:
o perfect HF sealing
o secure 360° bonding
o EMC protection to terminal point
o Continuous or stripped braid
o Pg and M threads
o individual variants
o compact design
o fast and safty installation |

QUIETSHIELD™ EMI/RFI Gaskets maintain shielding effectiveness (SE) across a seam or gap in the electronic equipment's shielding material. They consist of metalized fabric wrapped around a neoprene elastomer core. This provides a low cost solution, which allows you to utilize many material combinations and product designs never before practical. QUIETSHIELD™ gaskets provide unique solutions to your most stringent shielding, grounding, ESD and packaging requirements. It's the cost-effective avenue for creativity in design. Profile gaskets are currently available in four shapes: 'D', 'R', 'L', and 'P'. Spectrum's proprietary manufacturing method for making profile shielding gaskets is also ideally suited to custom profiles. New shapes and sizes can be manufactured with minimal lead times and low tooling costs. Changes can be easily made to the rubber core material, type of fabric or foil covering, and adhesive systems. Shielding specialists are at your disposal to help you with your custom designs. These specialists use design for manufacturability concepts to produce designs which meet your specific requirements at a reasonable cost.

Electromagnetic interference (EMI) can be described as any type of electrical interference, signal or noise, which temporarily or permanently effects the ability of electrical or electronic equipment or systems to function correctly. This phenomenon is familiar to everyone, even if we do not have a fundamental understanding of (EMI) principles.
Most people have witnessed and experienced the effects of interference whilst watching television when someone nearby is operating an electrical device. An other well know president is the mobile phone which disturbs the electronic equipment on board of aircrafts.
This interference, which is also referred to as Radio Frequency Interference (RFI), is active throughout the environment. Its effects can vary from distorting
electrical measurements, activating equipment at random (Health & Safety Issue), creating severe disruption of testing, communications, data handling, medical and defence activities.
ELDON’s Approach to shielding Enclosures

Electronic equipment with various types of indicative performance or viewing devices, such as digital read-outs or displays, may require protection from radiated electrical energy (EMI/RFI). Typical applications include EMI/RFI shielding for electronic displays and enclosures used in medical, avionic, telecommunication, military and industrial equipment.
These unique windows are designed to enhance clarity in viewing while, at the same time, introduce a high degree of shielding to prevent equipment damage due to impinging radiated electrical energy. Transmittance, conductivity, and image quality can be adjusted or tuned to fit the needs of specific applications.
Metex offers a wide range of custom-shielded optical windows for displays requiring EMI radiation or susceptibility shielding to meet military, TEMPEST or NSA specifications. Our Shielded Windows have been designed into commercial and military equipment to provide highly effective electromagnetic shielding while providing exceptional optical clarity and resolution. |
