Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
How It Works:
The shielding layer acts as a Faraday cage, absorbing or reflecting external electromagnetic waves (e.g., from power lines, radio transmitters, or nearby electronics).
Simultaneously, it confines the cable’s internal signals, minimizing crosstalk in multi-cable setups.
Performance Metrics:
Shielded coaxial cables achieve 90–99% EMI suppression, depending on shielding type (e.g., single braid vs. foil-braid combinations).
Example: In industrial automation, shielded RG-214 cables with double braided shields ensure stable data transmission near heavy machinery.
2. Enhanced Signal Integrity Over Long Distances
Shielding preserves signal quality by reducing attenuation and external noise pickup.
Low Signal Loss:
High-quality shields minimize dielectric losses and skin effect, especially in high-frequency applications (e.g., 5G networks, satellite communications).
Example: Heliax cables with copper outer conductors and foam dielectric maintain signal integrity over kilometers in broadcast towers.
Phase Stability:
Shielding prevents phase distortion caused by external fields, critical for radar systems and precision measurement tools.
3. Durability in Harsh Environments
Shielding layers add mechanical robustness and environmental protection.
Abrasion and Moisture Resistance:
Shields made of aluminum or stainless steel foil protect against physical damage and moisture ingress.
Example: Underground CATV systems use flooded coaxial cables with bonded foil shields to withstand soil acidity and water exposure.
Temperature Tolerance:
High-temperature shields (e.g., nickel-plated copper) enable use in aerospace or automotive engine compartments.
4. Compliance with Regulatory Standards
Shielded coaxial cables meet stringent EMI and safety regulations across industries.
Key Standards:
FCC Part 15: Limits EMI emissions from electronic devices in the U.S.
IEC 61196: Specifies shielding requirements for RF coaxial cables.
MIL-DTL-17: Mandates shielding performance for military-grade cables.
Applications:
Medical devices (e.g., MRI machines) rely on shielded cables to comply with electromagnetic compatibility (EMC) directives.
5. Versatility Across Applications
Shielded coaxial cables adapt to diverse operational needs.
Broadband and Telecommunications:
Tri-shielded RG-6 cables (foil + braid + foil) reduce ingress noise in cable TV and broadband networks.
Defense and Aerospace:
Double-shielded Teflon cables resist jamming and eavesdropping in military communication systems.
Consumer Electronics:
Miniature shielded coax (e.g., micro coaxial cables) ensures noise-free signals in smartphones and wearable devices.
Shielding Types and Their Trade-offs
Shielding Type Structure EMI Protection Flexibility Cost
Single Braided Shield Interwoven metal strands (e.g., copper) 85–90% High Low
Foil + Braid Shield Aluminum foil + braided layer 95–99% Moderate Moderate
Tri-Shield Foil + braid + foil >99% Low High
Solid Conduit Shield Rigid metal tube (e.g., aluminum) 99.9% None Very High
