A Multi-Pair Snake Cable, Belden 9729 is a low capacitance digital audio cable used in EIA RS-232/422 applications. Belden 9729 has a nominal impedance of 100 Ohm and comes with 2 pairs of 24 AWG stranded tinned copper conductors. It is protected from RFI and EMI interference by a 100% Aluminum foil-Polyester tape Beldfoil shield, plus a 90% tinned copper braid. The jacket is CM rated PVC.
Belden paired products deliver low voltage analog data signals within enclosures, from controllers and I/Os to devices such as temperature and pressure sensors, relays, valves, meters, thermocouples, solenoids, actuators, contacts, push buttons, and alarms. They also are applicable for computers, communications, instrumentation, sound, control, audio, data transmission, and many more applications.
Belden meets the demand for highly effective shielding technology with innovative, EMI/RFI-protective foil and braid designs like Beldfoil. Belden's patented Beldfoil shield is an aluminum/polyester foil construction that yields a lightweight, strong, flexible and thin shield that provides extra insulation and 100% shield coverage. Beldfoil is ideally suited for multiple-pair, individually shielded audio, communication, and data cables.
Datalene® insulation features include low dielectric constant and a dissipation factor for high-speed, low-distortion data handling. Physical properties include good crush resistance and light weight.
