Extron MHR-5P BNC/50 (part number 26-378-05) — a 50 ft (15.2 m) plenum-rated five-conductor BNC cable assembly for building-scale analogue video runs.

Once a run reaches fifty feet, the five RGBHV legs have to be treated as one cable or they will not stay matched. Extron builds them that way from the start: five 26 AWG, 75 ohm coaxial conductors sharing a jacket, each colour coded, each double shielded against its neighbours, and each terminated in a 75 ohm BNC. The mini high resolution coax keeps the finished bundle manageable at this length, and the NEC CMP plenum rating means the run can take the ceiling route rather than the long way round.

Key Capabilities

• 50 ft (15.2 m) length, measured tip-to-tip including connectors
• Five 26 AWG, 75 ohm coaxial conductors under one jacket
• Double shielded so the five legs do not interfere
• NEC CMP plenum rated for ceiling and return-air routing
• 75 ohm BNC connectors on all ten terminations
• Factory-matched leg lengths, no field trimming required

Where It Is Used

Equipment room to auditorium projector runs, control room to display wall links, and campus AV where an Extron switcher or distribution amplifier feeds a display in another part of the building over legacy RGBHV infrastructure.
