Description
The SMB Female (Jack) Crimp Connector is a precision-machined RF interface designed to provide a reliable signal path for cables with an outer diameter of approximately 4.9mm to 5.0mm. This variant is specifically optimized for high-performance 50-Ohm cables, including the flexible RG58, the high-temperature/high-power RG142, and low-loss LMR-195/LMR-200 series. The connector utilizes a heavy-duty crimp termination for both the center pin and the outer ferrule, ensuring an industrial-strength mechanical bond that withstands cable tension and environmental stress.
Designed for seamless operation from DC up to 4 GHz, the SMB interface features a spring-loaded snap-on coupling mechanism. This allows for rapid “click-lock” mating without the need for threading, making it an ideal choice for high-density panels or internal chassis wiring where space for a torque wrench is limited. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, this connector ensures minimal signal attenuation and superior protection against oxidation in demanding outdoor or industrial environments.
Key Technical Advantages
-
Broad Cable Versatility: Precision-calibrated to fit the specific dielectric and jacket dimensions of RG58, RG142, LMR-195, and LMR-200, ensuring a perfect 50-Ohm impedance match and low VSWR.
-
Rapid Snap-On Integration: The tool-free mating mechanism ensures a secure, vibration-proof connection, significantly reducing installation and maintenance time in the field.
-
Industrial-Strength Crimp: The dual-crimp design provides exceptional pull strength and shielding effectiveness, protecting the signal path against mechanical failure.
-
Superior Signal Integrity: High-conductivity gold plating on all critical contact surfaces ensures low contact resistance across thousands of mating cycles.
-
Vibration-Resistant Design: The snap-on interface is inherently resistant to loosening caused by mechanical shock or vibration, providing higher reliability than threaded connectors in mobile applications.
