Bochuang Spacetime 4-Hole Flange SMA Female RF Connector — Secure Panel Mount for High-Frequency Signal Transmission Through Walls
In complex industrial communication and microwave systems, signal entry points on equipment enclosures are often the weakest link in the entire chain. Bochuang Space-Time's4-hole flange
SMA Female ConnectorRF connectorsDesigned specifically to solve signal penetration and mounting challenges for chassis, shielded rooms, and base station panels. It's not just a connector—it's
A critical barrier ensuring the system's electromagnetic compatibility and mechanical stability.
Core Advantages & Technical Highlights:
Four-hole flange mounting for ultimate anti-vibration and anti-loosening performance:
Unlike standard nut-based fastening, this connector uses a standardFour-Hole Square Flange DesignTighten with four screws diagonally for extremely uniform
Force distribution. In environments with vehicle-mounted radar, aerospace systems, or heavy machinery vibration, it effectively prevents interface loosening and displacement due to prolonged vibration, ensuring absolute physical connection integrity.
Secure.
Precision 50Ω impedance matching, low VSWR transmission:
The internal insulator is made of high-performance PTFE (polytetrafluoroethylene) with a stable dielectric constant. Precision machining ensures the characteristic impedance is strictly controlled within50Ω ±1ΩFan
Within the range, maintain an extremely low Voltage Standing Wave Ratio (VSWR < 1.3) across a wide bandwidth of DC-18 GHz (and even higher frequencies) to minimize signal reflection.
Ensure complete transmission of weak signals.
Full gold-plated construction for superior conductivity and corrosion resistance:
The center pin and external thread are bothFull gold platingUnlike local plating, this process provides a thicker protective layer that effectively resists salt spray corrosion and oxidation.
For devices exposed to outdoor or harsh industrial environments, it ensures extremely low contact resistance even after thousands of mating cycles, preventing signal degradation.
Superior shielding performance, no signal leakage:
The brass body and panel fit tightly together, and the grounding design with the metal flange creates a complete360-degree electromagnetic shielding ringThis effectively blocks external electromagnetic interference.
Seal the device interior while preventing high-frequency signal leakage, meeting stringent EMC standards.
Broad Compatibility, Standardized Installation:
Complies with industry-standard flange dimensions, ensuring perfect compatibility with various standard SMA male cables and adapters. Widely used inRF module，5G micro base stations, satellite communication
Antennas, Vector Network Analyzers, Microwave Components, Military Communication EquipmentIdeal for high-end applications. A cost-effective choice for system integrators assembling and maintaining equipment.
