Description
The SMA Female 2-Hole Flange Crimp Connector is an industrial RF component engineered for permanent panel installations. Unlike single-hole bulkhead designs that can loosen or spin under torque, the 2-hole flange is secured with two screws, ensuring a rigid, stationary interface. This makes it ideal for external antenna ports on equipment where a secure, tamper-proof connection is required.
Optimized for thin-profile cables with an outer diameter of approximately 0.100″ (2.5mm), this connector utilizes a hex-crimp termination method for the outer ferrule. This creates a 360-degree mechanical bond between the cable braid and the connector body for maximum pull-strength. Constructed with gold-plated brass and high-purity PTFE (Teflon) insulation, it maintains a stable 50 Ohm impedance and low VSWR across frequencies up to 12.4 GHz, providing a professional-grade solution for telecommunications, aerospace, and test instrumentation.
Key Technical Advantages
-
Anti-Rotation Flange Mount: Two-hole bolt-on design prevents the connector from rotating or loosening during repeated cable mating cycles.
-
Space-Efficient Integration: The compact flange footprint (typically 15.88mm x 6.35mm) allows for high-density connector layouts on custom panels.
-
Broad Sub-Miniature Support: Fits multiple popular thin cables including RG174, RG316, and LMR100, simplifying inventory for custom pigtail manufacturing.
-
Enhanced Grounding: The flat flange provides a larger surface area for electrical contact with the chassis, ensuring excellent EMI/RFI shielding.
-
Maximum Conductivity: High-purity gold plating on the internal socket and body ensures low insertion loss and protection against environmental oxidation.
Key Features
-
2-Hole Flange Mounting: Designed for secure screw-down attachment (typically 12.7mm center-to-center hole spacing).
-
Standard SMA Female Interface: Features external threads and a gold-plated beryllium copper socket.
-
Premium PTFE Dielectric: High-grade insulator ensures thermal stability and low signal attenuation at high frequencies.
-
3-Piece Crimp Assembly: Includes the flange body, center contact socket, and outer crimp ferrule for reliable installation.
-
High Mechanical Strength: Machined from brass and rated for at least 500 mating cycles.
