Belden BAV 179DT 010, Coax Sub Miniature 28 AWGH PE SH PVC Black

Belden BAV 179DT 010 is a low loss serial digital coax in ultra-miniature RG-179/U form for precision 75 Ohm video and telecom signal paths. It features a 28.5 AWG solid bare copper conductor with gas-injected foam PE insulation and a PVC jacket. Dual shielding combines Duofoil® (100%) with a 95% tinned copper braid, and the cable is rated Riser-CMR with a UL voltage rating of 300 V RMS.

Key Features

• This low loss serial digital coax uses an ultra-miniature RG-179/U form for precision 75 Ohm signal paths.
• It has a 28.5 AWG solid bare copper conductor (1 conductor).
• Gas-injected foam PE insulation uses a white color code.
• Dual shielding combines Duofoil® (100%) with a tinned copper braid (95%).
• A PVC jacket provides a Riser-CMR rating for indoor riser environments.
