Belden MRG5800 Series Coaxial Cable, 50Ω Characteristic Impedance, 500m Cable Length - MRG5800.00500
This coaxial cable is designed for signal transmission and high-voltage DC applications across a wide temperature range. It combines a stranded tin‑plated copper central conductor with a polyethylene outer sheath and a characteristic impedance suited to 50 Ω systems. The construction and materials support deployment where low smoke zero halogen fire behaviour is required and CE conformity is recorded.
Features and Benefits:
• 4000V DC insulation offers safe high‑voltage handling
• 20 AWG stranded core provides flexible conductor performance
• 19 x 33 AWG core structure enhances signal consistency
• Polyethylene jacket delivers Durable environmental protection
• IEC 60332‑1‑2 LSZH rating reduces smoke and halogen emissions
• 20 AWG stranded core provides flexible conductor performance
• 19 x 33 AWG core structure enhances signal consistency
• Polyethylene jacket delivers Durable environmental protection
• IEC 60332‑1‑2 LSZH rating reduces smoke and halogen emissions
Applications
• Suitable for RF systems requiring 50 Ω impedance
• Ideal for 500 metre cable runs on reels
• Used with test equipment needing high‑voltage tolerance
• Can be used for installations needing LSZH fire behaviour
• Suitable for outdoor or controlled‑temperature installations

• Suitable for outdoor or controlled‑temperature installations
What conductor material is used to reduce corrosion risk?
The central conductor is MADE from tin‑plated copper strands which combine conductivity with improved oxidation resistance.
How does the cable perform at low temperatures?
It remains operational down to -40°C without loss of specified electrical characteristics.
What is the cable’s outer diameter and construction type?
The cable has an outside diameter of 4.95mm and uses a stranded conductor format.
Which approval verifies regulatory conformity for this cable?
It carries CE approval indicating conformity with applicable EU safety requirements.
How many conductor strands form the core and what gauge is the overall wire?
The core comprises 19 strands of 33 AWG each, producing an overall 21 AWG conductor.
