Belden Security & Sound, #22-4c BC, Shielded Multi-Conductor Cable, 4 Conductors, 22 AWG, Bare Copper, CMR, 300V, Grey PVC Jacket

Running low-voltage wiring for security systems, sound installations, or data links often means fighting noise, crosstalk, and unreliable connections. This Belden Security & Sound cable solves that with a Beldfoil® shield and drain wire that reject interference, while four 22 AWG bare copper conductors deliver clean, stable signals over long runs.

Who is it for

Installers and integrators who need a dependable multi-conductor cable for EIA RS-232/422 data, security sensors, or audio feeds in commercial and residential projects. It suits anyone who values proven Belden quality and a riser-rated jacket for in-wall vertical runs.

Main features

• 4 conductors, 22 AWG (7x30) bare copper for excellent conductivity and flexibility
• 100% Beldfoil® aluminum foil-polyester shield with 24 AWG tinned copper drain wire
