Belden 1855A 006, Coax Sub Miniature 23 AWG PE FR PVC Light Blue

Belden 1855A 006 is a 75 Ohm SDI coax designed for high-performance digital video, including 6 Gb/s UHDTV and HD-SDI 1080p. This mini RG-59 style cable uses a 23 AWG solid bare copper conductor with PE - Polyethylene (Foam) insulation and a PVC jacket. Shielding combines Duofoil® tri-laminate tape (100%) with a 95% tinned copper braid, and return loss is verified through 6000 MHz. It carries a UL voltage rating of 300 V (CMR, CMG) and is specified for UL temperature 75°C with an operating temperature of -30°C to +75°C.
