By Impedance

50 Ohm BNC Connectors
Primarily used in RF and telecommunications applications, including radio antennas, test equipment, and data communication systems. They offer optimal signal integrity for high-frequency transmissions.

 

75 Ohm BNC Connectors
Commonly found in video and broadcast applications, such as CCTV cameras, HD-SDI video systems, and cable TV networks. These connectors minimize signal loss in video transmission.

By Mounting Method

Cable-Type BNC Connectors
Designed for terminating coaxial cables, these connectors are further categorized by their attachment method:

Solder-Type BNC: Requires soldering the center conductor and shield for a permanent connection. Often used in custom cable assemblies.
Crimp-Type BNC: Uses a crimping tool to secure the connector onto the cable, providing a robust and reliable connection. Popular in field installations.
Compression-Type BNC: Compresses the connector onto the cable for superior mechanical stability and weather resistance. Ideal for outdoor or harsh environments.

 

Panel-Mount BNC Connectors
Used for securing BNC connections to equipment panels or enclosures:

Bulkhead-Mount BNC: Installed through a drilled hole in a panel, secured with a nut. Provides a stable connection point for equipment interfaces.
Flange-Mount BNC: Features a flange for surface mounting, often used in rack-mounted systems or industrial control panels.

 

BNC PCB Connectors
Designed for direct integration with printed circuit boards (PCBs):

Through-Hole BNC: Soldered into plated through-holes on the PCB, offering strong mechanical retention.
Edge-Mount BNC: Mounted along the edge of a PCB, commonly used in modular test equipment.
Surface-Mount (SMD) BNC: Soldered directly onto PCB pads, saving space in compact electronic designs.

By Orientation

Straight BNC Connectors: The standard configuration where the connector aligns linearly with the cable or panel.


Right-Angle BNC Connectors: Features a 90-degree bend, useful in tight spaces where cable routing requires a low-profile connection.

By Polarity

Standard BNC Connectors: Follows conventional gender definitions—male connectors have a center pin, while female connectors have a socket.

 

Reverse-Polarity BNC (RP-BNC) Connectors: Swaps the gender of the center contact (female center pin in male housing, or vice versa) for security in specialized applications.

FAQ

 

 

Q: What types of BNC cables do you customize?

A: We offer custom BNC cables with 50-ohm or 75-ohm impedance, suitable for RF, video, broadcast, CCTV, and instrumentation applications. Available in straight or right-angle connectors, with various coaxial cable types (RG58, RG59, RG174, etc.).

Q: Can you produce BNC cables for both analog and digital signals?

A: Yes. Our BNC cable assemblies support analog signals (such as CVBS video) and digital formats like SDI (Serial Digital Interface), HD-SDI, and 3G-SDI, depending on your bandwidth and shielding needs.

Q: Do you offer custom lengths, colors, and overmolding for BNC cables?

A: Absolutely. We can manufacture cables in custom lengths, jacket colors, and offer strain reliefs or overmolded connectors for durability and branding.

Q: Are your BNC cables tested before shipment?

A: Yes. Every BNC cable is 100% tested for continuity, impedance, and signal integrity. High-frequency versions are also tested for return loss and insertion loss.

Q: Can you provide bulk production as well as low-volume or prototype orders?

A: Of course. We support everything from small-batch prototypes to large-volume production, with fast turnaround and consistent quality control.

Q: What is the difference between a BNC connector and a SMA connector?

A: Both BNC and SubMiniature version A (SMA) connectors are used in high-frequency applications, but they have different designs and specifications. SMA connectors are typically used in applications that require higher frequencies and tighter tolerances, while BNC connectors are less expensive and more widely available.

Q: How do I terminate a BNC connector on a cable?

A: Terminating a BNC connector involves stripping the cable, exposing the inner conductor and insulating layers. Carefully attach the connector and ensure a secure connection. Proper termination is crucial for maintaining signal integrity, especially in high-frequency applications.

Q: Could I use BNC connectors for 4K video transmission?

A: BNC connectors are suitable for transmitting high-definition video signals, including 4K. However, it's crucial to use high-quality cables with the necessary bandwidth to support the higher resolution. Ensure that both the connectors and cables are rated for the desired video quality to maintain a clear and reliable signal.

Q: What is the difference between BNC and RCA connectors?

A: While both BNC and RCA connectors are used in audio and video applications, they have distinct differences. BNC connectors provide a twist-and-lock mechanism for secure connections, often used in professional settings. RCA connectors, on the other hand, use a push-and-twist mechanism and are more common in consumer audio and video setups.

Q: Can I connect BNC cables to my TV?

A: Connecting BNC cables to your TV depends on the available ports. If your TV has BNC input ports, you can use BNC cables for video signal transmission. However, modern TVs typically use HDMI or other digital connections. In such cases, you may need adapters to connect BNC cables to your TV.
