About Belden 9540 Cable
Computer EIA RS-232 Cable, 24 AWG stranded (7x32) tinned copper conductors, semi-rigid PVC insulation, overall Beldfoil shield (100% coverage), 24 AWG stranded tinned copper drain wire, PVC jacket.
Optimal Signal Protection for Sensitive ApplicationsBelden 9540's combination of individually shielded pairs and an overall aluminum foil shield with tinned copper drain wire minimizes electromagnetic interference and signal loss. This makes it especially suitable for sensitive control systems, industrial instrumentation, and secure audio or data circuits that demand clear signal transmission.
Built for Long-Term Reliability and Easy InstallationEngineered for fixed indoor use, Belden 9540's tough PVC jacket and insulation withstand operation and storage temperatures from -20C to +75C. Its stranded round 20 AWG conductors offer flexibility for routing, while a maximum pull tension of 35 lbs and a 3-inch bend radius support smooth, damage-free installation.
FAQ's of Belden 9540 Cable:
Q: How does the shielded design of the Belden 9540 cable enhance performance?
