Description
The SMB Male (Plug) Crimp Connector is a subminiature RF interface designed for rapid, tool-free integration in high-density electronic assemblies. Specifically optimized for the small-form factor of LMR-100, RG-174, and RG-316 cables, this connector provides a robust mechanical and electrical bridge for signal transmission. The design utilizes a high-precision crimp termination for both the center pin and the outer ferrule, ensuring an industrial-strength bond that maintains a stable 50-Ohm impedance.
Built to perform from DC up to 4 GHz, the SMB male interface features a snap-on coupling mechanism that “clicks” securely into place with any standard SMB female jack. This snap-on design is particularly advantageous in high-vibration environments—such as automotive or industrial machinery—where threaded SMA connectors may be prone to loosening. Manufactured with a high-grade gold-plated brass body and premium PTFE (Teflon) insulation, this connector ensures minimal signal attenuation and superior resistance to corrosion and thermal cycling.
Key Technical Advantages
-
Triple-Cable Precision Fit: Calibrated to the exact outer diameter and dielectric tolerances of LMR-100, RG-174, and RG-316 (approx. 2.5mm–2.8mm), ensuring a low VSWR and high shielding efficiency.
-
Vibration-Proof Snap-On Mating: The spring-loaded coupling mechanism provides a secure, vibration-resistant connection that significantly reduces installation time in the field or on the assembly line.
-
Superior Pull-Off Resistance: The dual-crimp design provides exceptional mechanical pull strength, protecting the signal path against accidental cable tension or rough handling.
-
High-Conductivity Gold Plating: Features premium gold-over-nickel plating on the center contact to minimize contact resistance and prevent oxidation over the connector’s lifespan.
-
Subminiature Space Efficiency: The compact profile allows for maximum port density on small PCB modules and wireless communication devices.
