BNC Jack Connectors (Female) Guide
What Are BNC Jack Connectors (Female)?
Tyclon’s BNC jack female connectors provide a dependable solution for coupling BNC interfaces in instrumentation, broadcast systems, and general RF applications. Manufactured with Japanese precision, they deliver stable impedance control and consistent electrical performance within the typical operating range of BNC systems.
Available in multiple configurations and mounting styles, our BNC jacks integrate seamlessly into oscilloscopes, signal generators, communication equipment, and custom assemblies. Each connector is engineered for secure bayonet locking, smooth mating, and reliable performance across standard RF environments, ensuring long-term usability in demanding professional applications.
50 Ω vs. 75 Ω
50 Ω is specialized for radio/data transmission (power transfer), while 75 Ω is optimized for broadcast/video transmission (minimal loss). Connecting different impedances causes reflection, making it essential to match the system impedance, especially above 200 MHz.
Mating of BNC Connectors
The BNC connector uses a bayonet lock system that connects and locks with a simple quarter-turn motion. This design makes it ideal for quick connections in CCTV, video, audio, antenna, and network applications.
BNC connectors mate through male and female interfaces, securely joining their center contacts. These BNC jacks (female) are designed to mate with BNC plugs (male). They are available in various configurations, including flange mount and bulkhead types, to support different equipment connection needs.
BNC Jack Connectors (Female) by Type
The BNC jack features a female interface on the mating side, while the opposite end is designed for connection to a coaxial cable.Within the BNC connector family, three primary jack types are available: straight jacks, bulkhead jacks, and flange jacks.
Trivia: Receptacle
The terms “plug” and “jack” refer to products designed for specific coaxial cable types.
Example:
- BNC plug for 3D-2V cable: BNCP-3
- BNC jack for 3D-2V cable: BNCJ-3
Another type of product designed for attachment to coaxial cables is the receptacle. Like jacks, receptacles typically have a female interface.
A receptacle can be installed on various coaxial cables as long as the diameter of the connector’s center contact matches the diameter of the cable’s center conductor. However, because it does not engage with the cable’s outer jacket, the connection is mechanically weaker. For this reason, receptacles are commonly used for internal wiring inside equipment enclosures rather than external connections.
Note: There are also “plug receptacles” with a male interface, though they are less common.

Insulated BNC Jack Connectors (Female)
The outer housing is constructed from insulating resin, preventing exposure of metal surfaces and helping protect sensitive equipment from overcurrent and overvoltage conditions. This connector remains fully compatible with standard BNC interfaces, making it ideal for electronic measuring instruments and recording equipment.Made-to-order product only.
Examples of BNC Plug Connectors (Male) Usage
Bulkhead jacks and flange jacks are differentiated by how they are secured to the equipment chassis.
Straight Plug (Male):Connects directly without bending, making it simple and versatile for general use where space behind the device is not limited.
Right-Angle Plug (Male):Also called a right-angle plug. Useful when the jack (female) on your device is positioned so that a straight plug would be inconvenient. Ideal when equipment must be placed against a wall or in a tight space with little room behind it.
BNC Jack Connectors (Female) Cable Installation Guide
BNC Jacks (female type) are typically mounted on equipment panels, but types designed to be attached directly to the end of a cable also exist, often serving as cable extensions or adapter cables. The basic installation procedure is as follows:
1. Connection of the Cente Contact and the Conductor
The inner conductor (core wire) of the cable is connected to the center pin (female side) of the jack. The connection method varies by product, but mainly includes the following processes:
- Soldering: The cable's core wire is fixed to the jack's center terminal using solder.
- Crimping (Compression): The center contact is fixed to the core wire by crimping it with a specialized tool.
2. Connection of the Connector Body and the Outer Jacket
The outer shield (braid) or outer jacket of the cable is secured to the connector body. This is crucial for ensuring the signal's ground connection and guaranteeing the cable's tensile strength.
The connection method is chosen based on the BNC Jack's design, such as crimping (fixed with a sleeve) or screw tightening (clamped between parts).
3. Cable Compatibility Check
BNC Jacks require compatible products that match the cable type to be connected. You must select the connector that suits the cable you intend to use.

BNC Jack Connectors (Female) FAQs
QWhat is the standard impedance of the BNC Jack (Female) connectors offered by Tyclon?
QWhat is the standard impedance of the BNC Jack (Female) connectors offered by Tyclon?
The standard impedance for Tyclon's BNC Jack female connectors is 50 Ω. This is essential for ensuring maximum signal transfer and minimum reflection loss when used in radio frequency systems.
QWhat is the primary coupling mechanism used by BNC connectors?
QWhat is the primary coupling mechanism used by BNC connectors?
BNC connectors utilize a quick and reliable bayonet locking mechanism. This design allows for fast connection and disconnection, while still providing a secure electrical and mechanical interface.
QWhat are the three main types of BNC Jack configurations available?
QWhat are the three main types of BNC Jack configurations available?
Tyclon offers three primary configurations for BNC Jacks: the Straight Jack for standard cable connections, the Bulkhead Jack for panel mounting, and the Flange Jack for secure four-hole mounting.
QHow does the Bulkhead Jack differ from the Flange Jack in terms of mounting?
QHow does the Bulkhead Jack differ from the Flange Jack in terms of mounting?
The Bulkhead Jack is secured to an enclosure by passing it through a hole and fastening it with a nut. The Flange Jack utilizes four holes for bolts or screws, providing a robust and stable mounting solution.
QWhat is a BNC Receptacle and where is it commonly used?
QWhat is a BNC Receptacle and where is it commonly used?
The BNC Receptacle has a female opening but usually connects only to the center conductor. It is mainly used for internal wiring applications inside a protective enclosure, where robust external attachment is not necessary.
QWhat is the maximum frequency range supported by the standard BNC 50 Ω series?
QWhat is the maximum frequency range supported by the standard BNC 50 Ω series?
The standard BNC 50 Ω series is designed to handle signals within a frequency range up to 4 GHz. This makes the connectors suitable for numerous radio frequency applications in communication and measurement instrumentation.
QCan you provide an example of a BNC Jack cable attachment method using solder and tightening?
QCan you provide an example of a BNC Jack cable attachment method using solder and tightening?
