Description
The BNC female 4-hole panel mount connector with a 12.7mm flange is a precision RF component designed for maximum space efficiency without compromising mechanical integrity. This variant features a 12.7mm square flange, providing the smallest standard footprint for a flange-mounted BNC interface. This makes it the premier choice for high-density equipment faces where space is at an absolute premium. The 4-hole mounting pattern ensures the connector remains perfectly fixed, providing far superior anti-rotation and vibration resistance compared to miniature bulkhead designs.
As a female interface (jack), it features the standard bayonet housing for rapid, secure mating with BNC male plugs. This model utilizes a solder cup termination for the center contact, ensuring a permanent, low-resistance electrical connection. This design is highly versatile and compatible with thin-diameter 50-Ohm coaxial cables typically used for internal chassis routing, such as RG178, RG174, or RG316. Manufactured with a durable nickel-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent signal integrity and reliable performance up to 4 GHz.
Key Technical Advantages
-
Ultra-Compact 12.7mm Flange: The miniature flange size allows for the highest possible port density on small equipment faces and modular sub-assemblies.
-
4-Hole Secure Mounting: Despite its small size, the four anchor points provide exceptional mechanical stability and resistance to torque during frequent mating cycles.
-
Universal Solder Termination: The rear solder cup allows for a direct electrical connection, making it ideal for custom micro-electronics and specialized internal wiring.
-
Standard Bayonet Housing: Features the industry-standard BNC female interface for rapid, tool-less mating that remains mechanically stable under physical stress.
-
Superior Corrosion Resistance: Features a precision-machined nickel-plated body and gold-plated center socket to ensure low contact resistance and long-term protection against oxidation.
