EMC shielding material for RF & LF fields, electrosmog and interference

In our EMC shielding materials category you will find products that significantly reduce electrical, magnetic and electromagnetic fields. The range covers HF (high-frequency) shielding materials for radio-frequency fields (e.g. mobile communications, WLAN, radar), NF (low-frequency) shielding materials for 50 Hz mains fields, as well as shielded electrical products, shielded luminaires and earthing accessories. :contentReference[oaicite:2]{index=2}

What are EMC shielding materials?

EMC shielding materials are used to attenuate or redirect electromagnetic fields and thus improve electromagnetic compatibility (EMC). Typical applications include protecting sensitive electronics against interference, reducing electromagnetic pollution (electrosmog) in buildings, complying with EMC standards and reducing unwanted emissions in industrial plants.

Depending on the frequency range, different materials are used: highly conductive fabrics, foils and coatings for high-frequency shielding, as well as soft-magnetic materials and special constructions for low-frequency electric and magnetic fields.

HF and NF shielding for different frequency ranges

For selecting the right EMC shielding material the operating frequency is crucial:

• HF shielding materials for radio-frequency fields, such as mobile communication (including 5G), WLAN, DECT, radio and radar signals
• NF shielding materials for low-frequency electric and magnetic fields, e.g. 50 Hz power lines, transformers or railway and industrial fields
• Material combinations and multilayer structures to achieve broadband shielding over different frequency ranges

Depending on the product, these materials are supplied as shielding fabrics, wallpapers, underlays, foils, panels or shielding paint. The achievable attenuation is typically specified in dB over defined frequency ranges.

Shielded electrical items, luminaires and earthing accessories

In addition to area shielding materials, PSE Priggen offers shielded electrical items and shielded luminaires that are designed for low emission of electric and magnetic fields. They are used, for example, in bedrooms and living areas, offices, laboratories or sensitive production environments.

Matching earthing accessories ensure that conductive shielding materials can be properly connected to the equipotential bonding system. This includes earthing tapes, terminals, cables and accessories for safe connection. Correct earthing is particularly important for HF and NF shielding in order to achieve the specified performance and safely discharge static charges.

Typical applications for EMC shielding materials

• Reducing electrosmog in homes, offices, schools and sensitive areas
• Shielding of measurement rooms, laboratories and test environments
• Improving EMC of control cabinets, controllers and electronic assemblies
• Shielding of cable routes, distribution boards and installation zones
• Supporting compliance with EMC directives and standards

Combining surface shielding (e.g. walls, ceilings, floors) with shielded luminaires, shielded electrical products and earthing accessories allows very high overall shielding performance.
