SMC M CRIMP for LMR100/RG174/RG316 Cable

Description

The SMC Male (Plug) Crimp Connector is a subminiature threaded RF interface designed for mission-critical environments where mechanical stability is paramount. While sharing a similar footprint with the snap-on SMB series, the SMC utilizes a #10-32 threaded coupling to ensure a secure, semi-permanent connection. This threaded interface maintains constant contact pressure and is highly resistant to loosening caused by mechanical shock and vibration, making it a preferred choice for onboard avionics, ruggedized industrial sensors, and mobile telecommunications equipment.

This variant is precision-calibrated for high-performance micro-diameter 50-Ohm cables, including LMR100, the flexible RG174, and the high-temperature RG316. It features a robust dual-crimp termination system for both the center conductor and the outer ferrule, providing an industrial-strength mechanical bond and excellent electrical continuity. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, the connector supports stable signal transmission and low VSWR (Voltage Standing Wave Ratio) from DC up to 10 GHz.

Key Technical Advantages

• Vibration-Resistant Threaded Security: The #10-32 threaded coupling prevents accidental disconnection and maintains signal integrity in high-motion environments where snap-on connectors may fail.

• Universal Micro-Cable Compatibility: Specifically engineered for the standard dimensions of LMR100, RG174, and RG316 (approx. 2.5mm–2.8mm OD), ensuring a secure mechanical grip and optimized signal path.

• Extended Frequency Performance: Precision-machined to support stable RF and microwave signal transmission up to 10 GHz, suitable for high-frequency GPS and wireless broadband applications.

• High-Strength Crimp Termination: The dual-crimp design ensures maximum pull-off resistance and superior EMI/RFI shielding effectiveness for sensitive data streams.

• Superior Corrosion Protection: High-grade gold-over-nickel plating on all critical surfaces ensures low contact resistance and prevents oxidation over long-term deployments.

Key Features

• Interface Type: SMC Male (Plug) with 50-Ohm threaded coupling.

• Cable Compatibility: Optimized for LMR100, RG174, and RG316 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 internal equipment wiring where threaded security is required in a small form factor.
