Belden 7789A B59, Coax Bundled Miniature 5C 23 AWG PVC Black Matte
Description
Belden 7789A B59 is a digital coax snake cable built as a 5-sub-miniature Mini 59 bundle for 75 Ohm video and broadcast applications. It uses 23 AWG solid BC - Bare Copper conductors with PE - Polyethylene (Foam) insulation and gas injected construction. Shielding is braid over foil, using Tri-Laminate (Alum+Poly+Alum), Duofoil®, 100% plus a Tinned Copper (TC), 95% braid. Designed as a Riser-CMR cable with a PVC - Polyvinyl Chloride jacket, it supports SMPTE 2081-1 6 Gb/s UHDTV, SMPTE 424M 3 Gb/s HD-SDI 1080p, and SDI/HDTV digital video.
