Cables To Go 40518 50 ft Plenum 3.5mm Stereo Cable

50 ft Plenum Stereo Cable

The C2G 40518 is a 50 ft plenum-rated 3.5mm stereo male-to-male cable built for commercial and educational audio runs that must meet fire-safety codes for air-handling spaces. Its CMP-rated jacket and foil-shielded 27 AWG copper conductors deliver clean analogue audio without interference in ceiling plenums or wall cavities. Installers who need compliant cable for long-distance stereo connections will find it purpose-built.

Low-Profile Install in Tight Spaces

Low-profile connectors measuring 1.5 inches deep and a 0.25 inch cable diameter allow the assembly to fit inside standard wall-plate boxes and narrow conduit without forcing bends. The solid 27 AWG conductors are stiffer than stranded alternatives, so sharp corners should be avoided during the pull to prevent conductor damage. Terminations are moulded and non-serviceable; verify the run length before cutting any slack.

Analogue Stereo Distance Limits

The 3.5 mm stereo interface carries unbalanced analogue audio, so signal degradation and noise pickup increase with run length even with foil shielding. At 50 ft the cable is suitable for line-level sources such as mixers, paging amplifiers or classroom AV switchers, but not for microphone-level signals or runs that exceed typical commercial ceiling spans. Users needing balanced audio or longer distances should select a different cable type.
