Description
BNC Jack (Female) | Solder Attachment | 4 Hole Flange | Brass Body
TThe ROSNOL BNC2GFA70-2940A/H4 is a high-performance RF connector designed for precision and reliability in demanding microwave applications. Featuring a BNC Jack (Female) configuration with solder attachment and a 4-hole flange mount, this connector ensures secure mechanical integration. Its stub terminal design and 12.7mm (.500 inch) hole spacing provide compatibility with standard mounting requirements.Engineered for optimal RF performance, the connector operates across a frequency range from DC to 4 GHz with a maximum VSWR of 1.43 (≥15 dB Return Loss), ensuring minimal signal reflection and consistent transmission quality. The bayonet coupling mechanism supports ≥500 mating cycles, offering durability and ease of use.
Constructed with high-grade materials, the center contact is made of phosphor bronze with 3 µinch gold plating over an 80 µinch non-magnetic nickel-phosphorus underplating. The body is composed of brass with a copper-tin-zinc alloy finish, while the insulator is PTFE, providing excellent electrical insulation and thermal stability.
All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
