Magnetic Shielding
Low-Frequency Protection
Low-frequency magnetic fields (1 Hz – 1 kHz) are generated by transformers, high-voltage lines, main low-voltage distribution boards, UPS systems, railway power systems, and tram overhead lines. In data centers and sensitive industrial environments, these fields can significantly impact electronic systems and operational stability.
According to EN 61000-4-8, electronic devices may malfunction at magnetic field strengths exceeding 3.75 µT. Many manufacturer requirements, particularly in data centers and semiconductor environments, demand even lower thresholds.
Why Magnetic Shielding?
Uncontrolled low-frequency magnetic fields may:
Interfere with servers and control systems
Cause data loss through coupling between power and data cables
Destabilize precision equipment
Create long-term exposure concerns for people
Recommended exposure limits for people are often set at 1 µT or lower. Our solutions follow the ALARA principle, reducing magnetic field strength to a technically controlled minimum.
