Description
The SMA Male 4-Hole Flange Panel Mount Connector is a precision RF component engineered for applications requiring maximum mechanical stability and electrical integrity. Unlike standard thread-on connectors, the 4-hole square flange allows the connector to be bolted directly to an enclosure or internal bulkhead. This creates an anti-rotation mount that protects internal solder joints from mechanical fatigue, even under high-vibration conditions.
Equipped with a solder-pin (solder-pot) terminal, this connector is optimized for direct internal wiring or PCB integration within a shielded box. The gold-plated brass body and PTFE (Teflon) insulator ensure a low-resistance signal path and exceptional thermal stability during the soldering process. It is widely used in aerospace, base station assemblies, and laboratory test fixtures where maintaining a consistent 50 Ohm impedance up to 18 GHz is critical.
Key Technical Advantages
-
Exceptional Mechanical Integrity: The 4-hole flange distributes physical stress evenly, preventing the connector from loosening or spinning during high-torque mating.
-
Superior Grounding Path: Flush mounting against a metal chassis provides a wide-area ground connection, significantly reducing EMI/RFI and signal leakage.
-
Low VSWR Performance: Precision-machined to maintain a strict 50 Ohm impedance, ensuring minimal signal reflection and high fidelity up to 18 GHz.
-
High-Purity Materials: Features gold-over-brass construction for maximum conductivity and lifelong corrosion resistance in demanding environments.
Key Features
-
4-Hole Square Flange: Allows for a flush, permanent mount on panels and racks using standard mounting hardware.
-
Solder-Pin Termination: Designed for clean and reliable internal electrical connections to coaxial pigtails or circuit boards.
-
Wide Frequency Range: Reliably supports high-speed data and microwave signals from DC up to 18 GHz.
-
Teflon (PTFE) Insulator: High-grade dielectric ensures stable electrical performance and high heat resistance during installation.
-
Standard SMA Male Interface: Features external threads and a gold-plated center pin for universal compatibility with SMA female jacks.
