Belden 9729 is a low capacitance, digital audio cable used in EIA RS-232/422 applications. This cable has a nominal impedence of 100 Ohm and comes with 2 pairs of 24 AWG stranded tinned copper conductors. This cable is protected from RFI and EMI interference by a 100% Aluminum foil-Polyester tape Beldfoil® shield. Each conductor is individually shielded and insulated by Datalene® FPE. Datalene® insulation features low dielectric constant and a dissipation factor for high-speed, low distortion data handling. The jacket is CM rated PVC.
