Neutrik NC3FXX-B 3-Pole XLR Female Cable Connector – Black/Gold

The Neutrik NC3FXX-B is a 3-pole XLR female cable connector featuring a black KTL-coated zinc diecast shell and gold-over-nickel contacts, representing Neutrik’s next-generation XX Series successor to the globally adopted X Series. The female contact uses a unique cage design for low contact resistance and a built-in solder barrier that prevents solder from running into the mating area during assembly—a common source of contact failure in other connectors. An improved solid metal latch is larger and easier to operate than the previous generation, and additional ground spring contacts improve shell ground continuity. The upgraded chuck-type strain relief provides higher pull-out resistance and faster assembly, while a polyurethane boot gland protects the cable entry from bending stress.

Key Features

• Cage design female contact — unique geometry delivers low contact resistance (≤3 mΩ) and high connection integrity
• Solder barrier — built into the female contact to prevent solder from flowing into the mating area during termination
• Gold-over-nickel contacts — 0.2μm Au hard alloy over 2μm Ni on bronze (CuSn8) contacts for reliable, long-term performance
• Improved solid metal latch — larger and easier to handle than previous X Series; secure latch lock engagement
• Additional ground spring contacts — improve shell ground continuity for better shielding performance
• Upgraded chuck-type strain relief — higher pull-out force than previous generation; faster and easier assembly
• Polyurethane boot gland — protects the cable entry point from repeated bending stress
• Black KTL shell coating — zinc diecast shell with black coating for a sleek, professional appearance
• Protected internal shell thread — recessed to prevent damage during assembly and handling
• Colored ring and boot options available — for channel coding and cable identification
