SMA Female to TNC Female BH Adapter

Description

The SMA Female to TNC 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 TNC Jack (Female) on the other. The body is specifically elongated and threaded on the TNC 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 TNC interface for internal SMA-terminated circuitry. The bulkhead design ensures that the connection remains fixed to the panel, preventing internal cable stress when external TNC cables are repeatedly connected or disconnected. Unlike bayonet-style BNC connectors, the threaded TNC interface provides superior mechanical stability in high-vibration environments. Precision-machined to ensure a constant 50 Ohm impedance, it is constructed with a heavy-duty nickel-plated brass body and PTFE (Teflon) insulation, maintaining exceptional signal integrity and low VSWR up to 11 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.

• Vibration-Proof Transition: The threaded TNC jack ensures a secure, locked connection that resists loosening under physical shock or extreme movement.

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

• 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.

Key Features

• SMA Female to TNC Female Interface: Consists of an SMA Jack (with socket and external threads) and a TNC Jack (with socket and external threads).

• Bulkhead Hardware Included: Comes complete with a mounting hex nut and lock washer for immediate panel installation.

• Nickel-Plated Brass Construction: Offers superior corrosion resistance and professional-grade durability for industrial, military, and test equipment applications.

• Premium PTFE Dielectric: Offers high thermal stability and maintains consistent electrical performance across its frequency range.

• Precision 50 Ohm Match: Specifically engineered to match standard high-performance wireless communication and microwave instrumentation.
