BNC 75 Ohm RGB Cables

High Resolution 75 Ohm RGB Cables

Video, Computer, High Frequency Work Stations
These cables are excellent for the latest video or computer work stations using RGB signals. Each cable uses a high-resolution 75 ohm mini-coax available in 3, 4, or 5 #28 gauge conductors. Complete assemblies with BNC, DB9, or DB15 connectors or in bulk cable rolls.

Multi-Conductor Coax Cable

The cables used in the manufacture of these assemblies exhibit fast rise times and are excellent for any type of application where miniature 75 ohm cable is required. Each conductor is double shielded, color-coded, and uses a #28 AWG 0.127mm coax.

MOGAMI 75 Ohm Coax Cable - W3145

Designed by MOGAMI for computers with Super VGA and higher scan rates, this heavier gauge cable carries the red, green, and blue signals and both syncs in one 0.385" jacket. It can be used as the "WRGB" above where top-of-the-line performance or any other computer or RGB application using five coax conductors is required.

Conductors are stranded for high definition with very low resistance for good conductivity.
