Belden 643948 877U, Surveillance CCTV Cable RG59 CMP 20 AWG FEP, Natural Jacket

Belden 643948 877U is an RG-59 coaxial surveillance cable for CCTV camera and security video runs in plenum spaces. It features a 20 AWG solid bare copper conductor, foam FEP insulation, and a low smoke PVC jacket. The cable is CMP rated, tested to NFPA 262, and provides 75 Ohm nominal characteristic impedance. Sequential footage marking every two feet helps simplify measuring and pulls.

Belden 643948 877U Key Features

• RG-59 coaxial construction (RG type: 59) for surveillance and CCTV camera video runs.
• 20 AWG solid BC - bare copper conductor for a consistent signal path.
• 95% bare copper (BC) braid shield for coverage and shielding performance.
• Low smoke PVC - polyvinyl chloride jacket with CMP rating for indoor plenum installations.
• Tested to NFPA 262 for flammability / reaction to fire requirements.
• Nom. characteristic impedance: 75 Ohm.
• Sequential footage marking every two feet to simplify measuring and pulls.
