Shielded Wall Panel: Panel Thickness 1.5 mm

Q: What is the typical shielding effectiveness of these panels?

Standard panels provide ≥60 dB attenuation at 1 GHz, suitable for most industrial EMC requirements; higher performance versions (up to 100 dB) are available for critical applications.

Q: Can shielded wall panels be customized for non-standard openings?

Yes, panels can be fabricated with custom cutouts for cables, vents, or windows, using conductive seals or waveguide vents to maintain shielding integrity.

Component Specifications

Definition

A structural component of a modular shielded enclosure system, engineered to provide electromagnetic compatibility (EMC) by attenuating electromagnetic emissions and preventing external interference from affecting sensitive equipment. It typically features conductive gaskets, welded seams, and specialized fasteners to maintain continuous electrical conductivity across panel joints, ensuring effective shielding across specified frequency ranges (e.g., 30 MHz to 18 GHz).

Working Principle

Operates on the principle of Faraday cage containment, where conductive materials (typically steel or aluminum with surface treatments) form a continuous shielded barrier. Electromagnetic waves are reflected and absorbed by the conductive surface, while seams and openings are sealed with EMI gaskets to prevent leakage, maintaining shielding effectiveness (SE) measured in decibels (dB).

Materials

Galvanized steel (SGCC) or aluminum alloy (5052/6061) with chromate conversion coating or nickel plating for corrosion resistance; silicone or beryllium copper EMI gaskets; stainless steel fasteners (A2/A4 grade).
