Product details

The 031-70552-12G: This is not a generic 50 Ohm RF BNC — the 75 Ohm impedance targets broadcast video, HD-SDI, and precision instrumentation applications where signal return loss matters. The 12 GHz maximum frequency is unusually high for a 75 Ohm BNC, putting this connector in the premium tier for high-bandwidth serial digital video links.

Cable Compatibility — Canare L-5.5CUHD and Beyond

The factory-specified cable is Canare L-5.5CUHD, a precision 75 Ohm broadcast coax with a 5.5 mm outer diameter. This connector is not listed as compatible with RG59 or Belden 1505F — those are different cable constructions with different dielectric diameters and impedance characteristics. Using this plug on an unspecified cable will shift the impedance and degrade the return loss at higher frequencies. For a BOM match, confirm the cable type before committing the line item.
