中文简体4.1-9.5 Connectors for Semi-Rigid & Semi-Flexible Cable Manufacturer
Product Overview
Semi-rigid and semi-flexible cables offer a unique combination of shielding effectiveness and controlled impedance that is difficult to achieve with conventional flexible coaxial cables. The 4.1-9.5 connector series for semi-rigid and semi-flexible cable is precision-machined to create a seamless, low-reflection mechanical and electrical interface between the cable and the system port. These connectors are specifically designed to maintain the outstanding phase stability and amplitude repeatability that semi-rigid and semi-flexible cable assemblies are valued for — particularly in bench and rack-mounted test instrumentation, high-density antenna feed networks, and RF distribution systems where cable routing precision is paramount.
Key Features
Precision-machined inner and outer conductors ensuring tight dimensional tolerances and consistent 50 Ω impedance
Purpose-designed ferrule and crimp/solder termination structures matched to common semi-rigid outer diameters (e.g., 0.085", 0.141", 0.250") and semi-flexible cable profiles
Shielding continuity: the connector body maintains full circumferential contact with the cable outer conductor, preserving the cable's inherent shielding integrity
Excellent VSWR and insertion loss performance across DC to 6 GHz operating range
Gold-plated or silver-plated center pin options for optimized conductivity and corrosion resistance
Stainless steel or passivated brass body options to suit indoor and outdoor installation environments
Low PIM design: careful control of plating processes and contact geometry minimizes passive intermodulation generation
RoHS compliant materials throughout
Competitive Advantages
Source Factory: Direct manufacturing with no intermediaries — factory pricing, consistent quality, and full traceability from raw material to finished connector.
25+ Years Experience: Founded in 1999, our engineering team has accumulated deep application knowledge in RF interconnect design for telecom, defense, and instrumentation markets.
Advanced Machining: Hanwha CNC lathes deliver micron-level tolerances on center pins and connector bodies, critical for achieving low VSWR in semi-rigid applications.
Triple Certification: ISO9001 quality management, ISO14001 environmental management, and GJB9001A military standard certification — the only way to credibly serve commercial and defense markets simultaneously.
Custom Capability: We accommodate non-standard cable OD sizes, special plating requirements, and customer-specified mechanical configurations with short lead times.
Typical Applications
5G base station antenna feed assemblies and phase-matched cable harnesses
Remote Radio Unit (RRU) and Active Antenna Unit (AAU) interconnects
Microwave backhaul and point-to-point link equipment
RF test and measurement bench setups requiring phase-stable interconnects
Defense and aerospace radar, communication, and electronic warfare subsystems
High-density RF distribution panels in DAS and small-cell deployments
FAQ
Q: What cable types are compatible with your 4.1-9.5 semi-rigid connectors?
A: Our connectors are available in versions matched to the most common semi-rigid outer diameters including 0.085", 0.141", and 0.250" copper-jacketed cable, as well as popular semi-flexible formats. Custom versions for non-standard ODs are available — please contact our engineering team with your cable specifications.
Q: How do you ensure consistent PIM performance in production?
A: We control PIM at the process level: precision plating thickness monitoring, burr-free machining of all contact surfaces, and 100% dimensional inspection. Our manufacturing facility references IEC 62037 guidelines for PIM-sensitive connector design.
Q: Can I get a sample for evaluation before placing a bulk order?
A: Yes. We support pre-production sample requests for qualified projects. Please provide your cable type, application frequency range, and environmental requirements and our sales engineering team will arrange samples promptly.
