中文简体BNC Connectors Flange Mount Connectors Manufacturer
Product Overview
The BNC Flange Mount Connectors are panel-mount termination solutions engineered for secure, vibration-resistant installation on instrument housings, chassis walls, and bulkheads. The flange—typically square or round—distributes mechanical load across multiple mounting points, making this connector family the preferred choice wherever repeated cable handling could otherwise stress a single-hole mount.
These connectors serve as the gateway between external coaxial cable infrastructure and internal circuit boards or instrumentation. Their panel-sealing options make them suitable for both pressurized and weather-protected enclosures, a requirement common in outdoor telecom installations, industrial control cabinets, and medical device chassis.
Key Features
Four-hole or two-hole flange patterns provide robust chassis attachment, dramatically reducing connector pullout risk compared to single-nut bulkhead styles.
Available in 50Ω and 75Ω versions with PTFE or other high-frequency dielectric insulation maintaining excellent electrical performance through the DC–4GHz band.
Solder cup, solder-post, and crimp rear termination options accommodate diverse PCB connection methods and cable assembly processes.
Panel cutout sealing option (with gasket) available for IP-rated installations where moisture ingress must be prevented.
Stainless steel or nickel-plated brass body variants available to address corrosion resistance requirements in marine or outdoor environments.
Standardized flange dimensions for drop-in replacement compatibility with industry-standard flange mount BNC footprints.
Competitive Advantages
With over 2,000 product SKUs across nearly 30 connector series, Jingcheng can consolidate BNC flange mount sourcing alongside related SMA, TNC, N-type, and MCX connectors—simplifying vendor management for procurement teams.
In-house electroplating and surface treatment processes ensure plating adhesion and thickness consistency that meet IEC and MIL-C plating specifications without relying on subcontracted finishing.
RoHS-certified materials throughout—solder-free termination options available for lead-free assembly lines, addressing environmental compliance requirements in EU, Japan, and California markets.
Factory-direct export experience with customers in the US, Germany, Japan, and Vietnam means export documentation (CO, test reports, material certifications) is routinely available and familiar to the sales team.
Typical Applications
Instrument and test equipment front/rear panels (oscilloscopes, signal generators, network analyzers)
Broadcast and AV equipment chassis BNC video input/output ports
Industrial IoT gateway and wireless sensor enclosures
Medical device RF port panels for patient monitoring and imaging systems
Telecom and network equipment rack-mount panels
FAQ
Q: Can the flange dimensions be customized to match our existing panel cutout pattern?
A: Yes. Custom flange hole patterns, bolt-circle diameters, and overall flange dimensions are available as engineering specials. Provide your panel drawing and we will confirm feasibility and lead time, typically within 3 business days.
Q: Is a sealed (IP-rated) version available for outdoor installations?
A: We offer versions with elastomer O-ring or gasket sealing at the panel interface. Please specify the required IP rating (e.g., IP65, IP67) and operating environment when requesting a quotation.
Q: What rear termination styles are available for PCB direct-mount versions?
A: Available styles include solder-post (through-hole PCB), edge-launch, and solder-cup for cable attachment. SMT footprint versions are not standard in the flange mount family but can be discussed for custom projects.
