Belden 639948 877, PTZ CCTV Power Audio Cable CMP RG6 18 AWG, Natural Jacket

Belden 639948 877 is a PTZ (CCTV + Power/Audio) composite cable for surveillance and CCTV camera installations in indoor plenum spaces. It combines 1-RG6 18 AWG solid bare copper coax with foam PE - Polyethylene (Foam) insulation and a 95% bare copper braid, plus 1-18 AWG stranded bare copper pair for power/audio/control. The Siamese Flamarrest® jacket is rated CMP with NFPA 262 flammability, and the coax is specified for 75 Ohm with 16.1 pF/ft capacitance. Supplied in a natural jacket and 1000’ length, it helps keep video and power/audio pulled together on longer PTZ runs.
