SMC F CRIMP for RG58/RG142/LMR195/LMR200 Cable

Description

The SMC Female (Jack) Crimp Connector is a specialized threaded RF interface designed for environments where mechanical security and electrical precision are mandatory. Unlike the snap-on SMB series, the SMC utilizes a threaded coupling to ensure a semi-permanent, stable connection. This variant is precision-machined to accommodate the larger physical profile of standard 5mm to 5.5mm diameter cables, including the widely used RG58, the high-temperature RG142, and low-loss LMR195/LMR200 series.

Built for performance up to 10 GHz, this connector features a dual-crimp termination for both the center conductor and the outer ferrule, providing industrial-grade mechanical retention and excellent EMI/RFI shielding. The robust threaded design makes it particularly effective in high-vibration aerospace and mobile communications applications where accidental disconnection is not an option. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it maintains low VSWR and exceptional signal integrity across a wide range of operating temperatures and environmental conditions.

Key Technical Advantages

• Vibration-Resistant Threaded Security: The #10-32 threaded interface provides a secure mechanical lock that prevents signal interruption in high-motion environments, such as avionics and industrial machinery.

• Versatile 50-Ohm Cable Compatibility: Precision-calibrated for the specific geometry of RG58, RG142, and LMR200-style cables, ensuring a perfect mechanical fit and stable impedance.

• High-Frequency Performance: Engineered to support stable signal transmission up to 10 GHz, making it suitable for microwave communications and high-speed data links.

• Superior Pull-Off Resistance: The dual-crimp design ensures maximum mechanical strength, protecting the sensitive internal signal path from cable tension or displacement.

• Corrosion-Resistant Gold Plating: Premium gold-over-nickel plating on critical contact surfaces ensures low contact resistance and long-term protection against oxidation.

Key Features

• Interface Type: SMC Female (Jack) with 50-Ohm threaded coupling.

• Cable Compatibility: Optimized for RG58, RG142, LMR195, and LMR200 coaxial cables.

• Termination Method: High-reliability crimp for both the center pin and the outer ferrule.

• Premium Construction: Features a gold-plated brass body and a high-performance PTFE dielectric for thermal and electrical stability.

• Compact Subminiature Design: Ideal for high-density chassis and internal wiring where threaded security is required in a small form factor.
