W3233
Multicore 75Ω coaxial cables used for HD TV RGB signal, VGA and CRT drive etc. are available in three versions. One small overall diameter version to meet shrink Dsub 15P connector and two large overall diameter version with less attenuation for longer runs offer the following outstanding features.
- Because of used XLCPE (Cross-Linked Cellular polyethylene) insulation, despite its compact overall diameter, lower attenuation value is realized. To reach the same attenuation level by regular solid PE insulated coax. cable, its overall diameter has to become more than 30% larger. Also, cross-linking makes this insulation more durable against soldering heat.
- All versions have featured MOGAMI flexibility so that they are convenient for handling, and its unique served (spiral) shielding construction and stranded center conductor helps easier wiring and installation.
- Medium overall diameter version is comprised of MOGAMI standard #W2964 (75W audio video cable), and one touch Push-Pull BNC male connector specifically designed for #W2964 cable is available so that your own original cable assembly and instant procurement from standard cable assemblies are both available. One touch Push-Pull BNC for large size version is also available.
