BNC connector adapter socket-to-socket EB1305779150 — female BNC coupler

Inline BNC connector adapter socket-to-socket EB1305779150 is a female-to-female BNC coupler designed to join two BNC male cables. The adapter provides a direct mechanical and electrical connection for coaxial cables without the need for signal converters, maintaining the characteristic impedance of the line when used with compatible cables and connectors. Its compact form factor and standard BNC female terminations make it suitable for quick extensions or repairs of video, CCTV and RF coaxial runs.

Advantages

The female BNC coupler offers a simple push-and-twist connection that ensures reliable mating with standard BNC male plugs. Its inline design minimizes additional cable bulk and allows easy placement in tight installations. Because it is passive, the adapter does not require power or introduce active circuitry; it preserves existing signal paths and is compatible with common analogue and digital BNC-terminated equipment.

Suitable for

• Extending coaxial video leads in CCTV systems
• Joining RF cables for test and measurement setups
• Temporary or permanent repairs of BNC-terminated cables
• Connecting BNC-terminated devices such as monitors, DVRs, and cameras

Key specifications

• Connector type: female-to-female BNC coupler
• Compatibility: standard 50/75 Ω BNC plugs (use matching impedance cables)
• Function: passive inline mechanical and electrical coupling
• Application: video, CCTV, RF and general coaxial connections
• Form factor: compact inline coupler for minimal added length

How to use

To use the BNC connector adapter, align the male BNC plug on the first cable with one female end of the coupler and push the plug into the socket. Twist the plug until it locks into place. Repeat the same procedure with the second male BNC cable on the opposite end. Ensure both connections are fully seated and locked to maintain continuity and reduce signal reflections. For best performance, use cables and equipment with matching impedance and maintain secure physical routing to avoid strain on the connectors.

Usage recommendations

Use the coupler in non-weather-exposed indoor environments unless additionally sealed; if used outdoors, protect the connection from moisture and corrosion with appropriate sealing or enclosures. Avoid repeated excessive bending or tension at the connection points and choose matching impedance cables to minimize signal loss or mismatch.
