The Extron 5 Conductor MHR Plenum Bulk Cable is a high-performance, plenum-rated cable designed for professional AV installations requiring reliable transmission of RGBHV video, component video, or composite video signals along with control or audio lines. Featuring five 26 AWG mini high-resolution (MHR) coaxial conductors with individual 95% tinned copper braid + aluminum foil shielding, this cable delivers excellent signal integrity, low attenuation, and superior rejection of electromagnetic interference over long runs. The plenum-rated CMP jacket complies with NEC requirements for use in air-handling spaces, making it suitable for in-ceiling, in-wall, conduit, or riser applications in educational facilities, corporate boardrooms, auditoriums, houses of worship, and large-scale presentation systems.

With a compact 0.295" (7.5 mm) outer diameter and flexible construction, the cable is easy to pull through tight pathways while maintaining structural integrity and performance. The blue jacket aids in quick identification during installation and termination, and the cable is optimized for use with Extron BNC connectors, crimp tools, and termination accessories to ensure consistent, high-quality connections in demanding AV environments.
