Component Specifications

Definition
A conductive elastomeric gasket designed to create an electromagnetic interference (EMI) and radio frequency interference (RFI) seal between mating surfaces of RF-shielded access doors, preventing signal leakage and maintaining shielding effectiveness across the door perimeter.
Working Principle
Works by compressing between door and frame surfaces to fill gaps, using conductive materials (typically metal-filled elastomers) to create continuous electrical contact, thereby maintaining the Faraday cage effect and preventing electromagnetic energy from escaping or entering through door seams.
Materials
Silicone or fluorosilicone elastomer filled with silver-plated aluminum, silver-plated copper, nickel-graphite, or silver-plated glass particles; Shore A hardness 40-70; operating temperature range -55°C to +200°C; flame retardant UL94 V-0 rated.
Technical Parameters
  • Compression Set <20% after 24 hours at 70°C
  • Compression Range 15-40% of free height
  • Volume Resistivity <0.01 ohm-cm
  • Environmental Rating IP54 minimum
  • Shielding Effectiveness 60-120 dB at 1-10 GHz
  • Compression Force Deflection 3-15 psi at 25% compression
Standards
ISO 22610, DIN EN 61373, MIL-DTL-83528, IEC 61000-4-3

Frequently Asked Questions

How often should RF sealing gaskets be replaced?

Typically every 3-5 years or when compression set exceeds 25%, visible damage occurs, or shielding effectiveness drops below required specifications.

Can RF sealing gaskets be used in outdoor environments?

Yes, when made with UV-resistant and weatherproof materials like fluorosilicone with appropriate environmental ratings (IP54 or higher).

What maintenance is required for RF sealing gaskets?

Regular inspection for compression, cleaning with isopropyl alcohol to maintain conductivity, and verification of shielding effectiveness using field test methods.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
