N Male Coaxial Crimp Connector for 1/2" Superflexible Cable

N Male Coaxial Crimp Connector for 1/2″ Superflexible Cable

High-Fidelity Connectivity for Demanding RF Networks

When routing cables through tight spaces in complex In-Building Antenna Systems (IBS) and public safety infrastructure, superflexible cables are essential. To match that flexibility without sacrificing signal integrity, Hefei BRI Electronic & Technology Co., Ltd. has engineered the NM-1/2″S.

This premium n male coaxial crimp connector is precision-manufactured specifically for 1/2″ superflexible RF cables. Built to stringent ISO 9001:2015 standards, this coax n type connector delivers the low-loss, low-PIM performance that modern Distributed Antenna Systems (DAS) require to maintain seamless, high-bandwidth cellular coverage.

Key Engineering Advantages

  • Optimized for Superflex: The specialized straight male design allows for secure, reliable termination on 1/2″ superflexible corrugated cables, ideal for tight routing in IBS deployments.

  • Ultra-Low PIM Performance: With a PIM3 rating of ≤-155dBc (2*43dBm), this connector virtually eliminates passive intermodulation, ensuring pristine audio and data transmission for critical public safety and telecom networks.

  • Extreme Weatherproofing: Engineered for both indoor and outdoor harsh environments, the IP68 sealing class guarantees complete protection against dust and water (submersible up to 1 meter for 24 hours).

  • Premium Trimetal & Silver Plating: The brass body and nut feature advanced trimetal plating, while the inner contacts are silver-plated. This combination drastically reduces insertion loss (≤0.10dB) and offers superior corrosion resistance over a long lifespan.
