Description
The SMA Male Crimp Connector for LMR240 is a precision RF component designed for applications requiring high signal integrity and mechanical durability. LMR240 is a popular low-loss cable, and this connector is sized to accommodate its specific dimensions, including the 0.240-inch outer diameter and foam dielectric.
The termination process utilizes a hex-crimp method for the outer ferrule, while the center pin can be either crimped or soldered depending on the specific model. This creates a permanent, 360-degree mechanical bond that ensures maximum pull-strength and superior electrical grounding. Constructed with a gold-plated brass or stainless steel body, these connectors maintain a strict 50 Ohm impedance and are typically rated for reliable performance from DC up to 6 GHz, with high-precision variants reaching 12.4 GHz.
Key Technical Advantages
-
Optimized for 240-Series: Specifically designed for the dielectric and shield diameters of LMR240, ensuring a perfect fit and preventing signal leakage.
