Neutrik NBNC75BLP9X Rear twist crimp (hex 6.47 mm) UHD BNC. For cables: SC-Vector (RCB); 1 x 0,80; PVC 6,00 mm

The Neutrik NBNC75BLP9X is a broadcast-grade, true 75 Ohm rearTWIST UHD BNC male cable connector.

While Neutrik's standard HD lines are designed for 3G-SDI, the UHD/X-Series features a re-engineered insulator material and a scaled-down center pin contact geometry. This construction limits return loss at extreme frequencies, allowing you to transmit uncompressed 4K (12G-SDI) and 8K Ultra-HD digital video over a single coaxial run.

This specific "P9X" version is engineered with an internal guide chamber tailored to fit precision video coax lines with an outer diameter (OD) of 6.0 mm to 6.3 mm, making it a perfect match for the Sommer Cable SC-Vector (RCB) 1 x 0.80 with a PVC jacket.

Critical Crimp Dimensions & Tooling

To meet strict broadcast return loss standards at 12 GHz and beyond, the crimp tolerances on this UHD variant are highly precise. Using an incorrect or older standard-definition/HD die set will pinch the cable's dielectric, resulting in high return loss, impedance mismatching, and signal dropouts.

⚠️ Tooling Warning: Standard HD BNC connectors from Neutrik typically utilize a 1.60 mm center pin crimp cavity. However, this UHD connector requires a smaller 1.07 mm square pin crimp. You must use a UHD-compatible crimp frame, such as the Neutrik HX-R-BNC, fitted explicitly with the DIE-R-BNCX-PDG die insert to guarantee a proper, specification-compliant termination on your SC-Vector cable.

High-Frequency Performance Profile

• Ultra-High Definition Signal Integrity: Provides exceptional Voltage Standing Wave Ratio (VSWR) headroom designed to scale far past baseline transmission expectations:

  • Less than or equal to 1.06 VSWR / greater than 30 dB return loss up to 6 GHz (6G-SDI benchmark)

  • Less than or equal to 1.13 VSWR / greater than 24 dB return loss up to 12 GHz (12G-SDI / 4K Broadcast standard)

  • Less than or equal to 1.22 VSWR / greater than 20 dB return loss up to 18 GHz (8K Video streaming target)

• Dark Antraloy Plating: The outer shell features a specialized Antraloy electroplating finish. This unique alloy treatment offers high protection against oxidization and corrosion while maintaining low contact resistance across a lifespan of more than 1,000 mating cycles.

Key Mechanical Design Elements

• The rearTWIST Soft-Touch Boot: This mechanism completely eliminates the need to reach into high-density routing blocks or packed patch panels to twist a rigid metal locking collar. Instead, you twist the flexible rubber boot at the back of the connector assembly to smoothly lock or release the bayonet latch.

• Jacket Crimp Shielding Technology: The metal ferrule clamps over both the copper ground shield braid and the outer PVC jacket simultaneously. This structural design ensures that any unexpected pulling or tugging forces are distributed evenly across the rugged outer cable jacket rather than stressing the critical internal center pin contact.
