Description
The SMB Female (Jack) Crimp Connector is a subminiature RF interface engineered for rapid and reliable cable assembly in space-constrained applications. It is specifically precision-machined to accommodate the thin-profile dimensions of LMR-100, RG-174, and RG-316 coaxial cables. The design utilizes a high-strength crimp termination for both the center contact and the outer ferrule, ensuring a permanent mechanical bond and consistent electrical performance.
Built for the 50-Ohm impedance standard, the SMB interface features a snap-on coupling mechanism that allows for quick mating and unmating without the need for threading or tools. This makes it an ideal solution for internal signal routing and high-vibration environments where a standard SMA might loosen over time. The connector body is manufactured from high-grade brass with premium gold plating, which offers superior conductivity and protects against oxidation. With its compact footprint and broadband performance up to 4 GHz, this connector is widely used in telecommunications, base station hardware, and industrial wireless modules.
Key Technical Advantages
-
Triple-Cable Versatility: Engineered with exact tolerances to provide a seamless fit for LMR-100, RG-174, and RG-316 series cables, ensuring minimal VSWR and signal leakage.
-
Rapid Snap-On Integration: The spring-loaded mating mechanism ensures a secure, “click-lock” connection, significantly reducing assembly and maintenance time in the field.
-
High-Strength Crimp Termination: The dual-crimp design provides exceptional pull strength, ensuring the cable remains securely attached even under mechanical stress or constant motion.
-
Superior Signal Integrity: Gold-plated center and outer contacts maintain low contact resistance and high conductivity across thousands of mating cycles.
-
Vibration-Proof Design: The snap-on interface is inherently resistant to loosening caused by vibration, making it safer than threaded connectors in automotive or aerospace applications.
