BNC Plug Connectors (Male) Guide
What Are BNC Plug Connectors (Male)?
Tyclon’s male BNC plug connectors deliver reliable bayonet-coupled connections with excellent impedance matching and low VSWR. Precision-engineered for stability and durability, they ensure consistent signal performance in test equipment, broadcast systems, and general RF applications. Built to Japanese standards, Tyclon connectors deliver dependable, long-lasting RF performance.
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 openings, securely joining their center contacts. Adapters are available in various configurations, including male-to-male, female-to-female, and male-to-female. Some designs also feature connectors with three mating interfaces to support more complex connections.
BNC Plug Connectors (Male) by Type
Male BNC plug connectors feature a male interface on the mating side and connect to a coaxial cable on the opposite end.In the BNC connector series, two main plug configurations are available: straight plugs and right-angle plugs, allowing flexibility for different installation layouts and space requirements.
Trivia: Plug Receptacles
Plugs and jacks vary for each type of coaxial cable.
Another type of connector for coaxial cables is the receptacle. Receptacles can fit any coaxial cable as long as the connector’s center contact matches the cable’s center conductor. However, because they don’t connect to the cable’s outer sheath, the joint is weaker, so they’re often used for internal wiring inside enclosures.
While receptacles usually have a female opening, BNC also offers plug receptacles with a male opening.
Examples of BNC Plug Connectors (Male) Usage
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):
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 Plug Connectors (Male) Waterproof Type
This plug is suitable for both indoor and outdoor use, including areas near water, places exposed to rain or wind, or humid environments.
Insulated BNC Plug (Male)
Designed with a fully molded resin housing, this connector eliminates exposed metal surfaces to prevent accidental contact. This insulation protects sensitive precision equipment from overcurrent and overvoltage risks. Fully compatible with standard BNC interfaces, it is the ideal solution for electronic measurement instrumentation and data recording devices.
BNC Plug Connectors (Male) Cable Installation Guide
BNC plugs are connectors used to attach coaxial cables, mainly for video signals and measurement equipment. The basic installation steps are as follows:
1. Connecting the center contact to the cable conductor
Insert the cable’s inner conductor (core wire) into the connector’s center pin. The connection method varies by product and can include soldering, nut tightening, compression (crimping), or screw fastening.
2. Connecting the connector body to the outer jacket
Secure the cable’s outer shield or jacket to the connector body. Depending on the BNC plug and cable type, this can be done by crimping or tightening.
3. Checking cable compatibility
BNC plugs are designed for specific cable types and sizes, so choose a connector that matches the cable you’re using.
