High-Performance 4.3-10 Male Connector for 1/2″ Feeder Cable
Product Introduction:
Meet the demands of next-generation cellular infrastructure with the 4310M-1/2CS 4.3-10 Male Clamp Connector. Designed specifically for 1/2″ flexible feeder cables (like 50-12 and LDF4-50A), this advanced 4.3 10 connector delivers industry-leading, ultra-low PIM performance (≤-163dBc) in a compact footprint. Rated IP67 for rugged outdoor use and operating efficiently up to 6GHz, it is the ultimate RF component for minimizing signal interference in high-density Distributed Antenna Systems (DAS), In-Building Antenna Systems (IBS), and mission-critical public safety networks.
The New Standard in Low-PIM RF Connectivity
As mobile networks evolve toward 5G and denser configurations, minimizing Passive Intermodulation (PIM) is more critical than ever. Trusted by global telecom partners—and showcased alongside our power splitters and directional couplers at major industry events like MWC Barcelona—Hefei BRI Electronic & Technology Co., Ltd. manufactures RF passive components that drive reliable connectivity.
This 4.3-10 connector is engineered to replace bulkier DIN connectors where space is at a premium, without sacrificing electrical or mechanical stability.
Ultra-Low PIM: Boasting an exceptional PIM rating of ≤-163dBc, this connector virtually eliminates unwanted noise, preserving data speeds and call quality in complex DAS environments.
Compact & Lightweight: The 4.3 10 connector design offers a significant reduction in size and weight compared to 7/16 DIN equivalents, allowing for denser port configurations on modern base station equipment.
Robust Weatherproofing: An IP67 sealing class ensures your connections remain completely protected against dust ingress and temporary water submersion.
Premium Materials: Built with a trimetal-plated brass body and silver-plated inner contacts for superior conductivity and long-term corrosion resistance.
