SMA F 4H panel Mount CRIMP for LMR100/RG174/RG316 Cable

Description

The SMA Female 4-Hole Flange Crimp Connector is the premier choice for high-reliability chassis mounting. Unlike bulkhead or 2-hole designs, the 4-hole square flange provides symmetrical tension across the mounting surface, eliminating any risk of the connector tilting or rotating under the weight of heavy mating cables. This design is preferred in military, aerospace, and high-precision laboratory equipment where physical port integrity is critical.

This connector is designed for thin, high-flexibility cables with an outer diameter of approximately 0.100″ (2.5mm). It utilizes a hex-crimp termination for the outer ferrule to ensure a vibration-proof ground connection. Constructed with gold-plated brass and a high-purity PTFE (Teflon) dielectric, it maintains a precise 50 Ohm impedance and low VSWR through 12.4 GHz, ensuring professional-grade signal performance in a ruggedized form factor.

Key Technical Advantages

• Maximum Mechanical Stability: The four-bolt pattern distributes mechanical stress evenly, preventing panel deformation and ensuring the connector stays perfectly perpendicular.

• Superior Anti-Rotation: Once bolted, the square flange makes it physically impossible for the connector to spin or loosen during cable installation.

• Broad Cable Support: Optimized for thin-profile low-loss cables like LMR100, RG174, and RG316, making it ideal for internal-to-external chassis transitions.

• Optimized RF Grounding: The large surface area of the square flange provides an excellent electrical bond to the metallic chassis, maximizing EMI/RFI shielding.

• High-Grade Materials: Gold plating over the entire body and center socket ensures low contact resistance and maximum protection against corrosion and wear.

Key Features

• 4-Hole Square Flange: Provides a secure, balanced mounting footprint (standard hole spacing is typically 12.7mm or 8.6mm square).

• Standard SMA Female Interface: Features external threads and a gold-plated beryllium copper socket.

• PTFE (Teflon) Insulator: Ensures consistent electrical properties and high thermal resistance for field or factory assembly.

• 3-Piece Crimp Design: Consists of the 4-hole flange body, the center contact socket, and the outer ferrule for a high-strength bond.

• Extreme Durability: Rated for a minimum of 500 mating cycles in demanding environments.
