Description
The SMA Female 2-Hole Panel Mount Connector is a precision RF interface engineered for applications where space is at a premium but mechanical stability remains critical. Unlike 4-hole variants, the 2-hole flange reduces the mounting footprint, making it ideal for high-density panels and compact electronic housings. The connector is secured to the chassis using two screws, providing an anti-rotation mount that protects internal solder joints.
Featuring a solder-cup or stub terminal, this connector allows for direct, low-resistance internal wiring. Its construction typically involves a gold-plated brass body and a Teflon (PTFE) insulator, ensuring superior signal clarity and thermal stability during the soldering process. It is a staple in Wi-Fi equipment, base stations, and satellite communication systems, maintaining high signal integrity across frequencies up to 18 GHz.
Key Technical Advantages
-
Compact Footprint: The 2-hole flange design allows for closer connector spacing on dense interface panels compared to 4-hole models.
-
Low VSWR & High Fidelity: precision-machined to ensure a consistent 50 Ohm impedance, minimizing signal reflection and insertion loss.
-
Superior Grounding: The flat flange provides a broad surface contact with the metal chassis, creating a low-impedance ground path to reduce EMI/RFI.
-
Exceptional Durability: Built to withstand over 500 mating cycles with a gold-plated finish that prevents environmental oxidation and corrosion.
-
High Frequency Range: Capable of handling high-speed data and microwave signals from DC up to 18 GHz.
Key Features
-
2-Hole Rectangular Flange: Provides a secure, permanent mount that prevents the connector from spinning or loosening.
-
Solder-Type Termination: Features a gold-plated solder cup or pin for reliable and easy internal electrical connections.
-
Premium Dielectric: Utilizes high-purity Teflon (PTFE) for stable electrical performance and high heat resistance.
-
Standard 1/4-36 Thread: Fully compatible with all standard SMA male (plug) interfaces.
-
Gold-Plated Beryllium Copper Contact: Ensures maximum conductivity and reliable mating force over time.
