Belden 8451 22/1 Pair Stranded Shielded Audio and Instrumentation Cable, TC, CM, PVC Jacket, Black

Engineered for reliable signal delivery in commercial installations, the Belden 8451 riser audio and instrumentation cable ensures clean, interference-free audio and sensor signals for security and surveillance systems. This 1-pair, shielded cable uses 22 AWG stranded tinned copper conductors to provide dependable conductivity and corrosion resistance while maintaining flexibility for fast, professional installations. The PVC riser jacket is rated for vertical building runs and protects the cable in conduit and plenum-adjacent spaces where riser-rated cabling is required.

Installers and system integrators benefit from the cable’s robust shielding that minimizes EMI/RFI—critical for clear monitoring, CCTV microphone feeds, access control, and instrumentation. The stranded construction makes termination and soldering straightforward, reducing labor time on large deployments. Designed by Belden, this cable delivers consistent audio fidelity and dependable instrumentation performance across security, surveillance and AV monitoring systems. Ideal for camera audio, intercoms, sensor lines and low-voltage instrumentation — specify Belden 8451 for your next riser installation and improve system reliability.
