SMA Female to BNC Female BH Adapter

Description

The SMA Female to BNC Female Bulkhead Adapter is a specialized “between-series” RF component designed for through-hole mounting on chassis, cabinets, or equipment panels. It features an SMA Jack (Female) on one side and a BNC Jack (Female) on the other. The body is specifically elongated and threaded on the BNC side to accommodate a “Bulkhead” installation, secured by the included hex nut and lock washer.

This adapter is indispensable for engineers who need to provide a rugged, external BNC interface for internal SMA-terminated circuitry. The bulkhead design ensures that the connection remains fixed to the panel, preventing internal cable stress when external BNC cables are repeatedly connected or disconnected. The BNC side utilizes a classic two-stud bayonet coupling for rapid attachment, while the SMA side provides a high-precision microwave interface. Constructed with a heavy-duty nickel-plated brass body and PTFE (Teflon) insulation, it maintains exceptional signal integrity and low VSWR up to 4 GHz.

Key Technical Advantages

• Secure Bulkhead Mounting: The integrated threading and mounting hardware allow the adapter to be fixed permanently to a panel, providing a stable external interface.

• Internal-to-External Bridge: Perfect for routing high-frequency signals from internal PCB-mounted SMA cables to a more accessible external BNC port.

• Rapid Connectivity: The BNC female interface allows for the quick attachment of probes and cables, making it ideal for high-traffic laboratory and diagnostic environments.

• Superior RF Shielding: The broad contact of the adapter body against the equipment chassis ensures an exceptional ground path, reducing EMI and signal leakage.

• Maximum Conductivity: High-purity gold or silver plating on both internal center contact sockets ensures ultra-low contact resistance and superior protection against oxidation.
