Lightweight Beryllium Bronze RF Coaxial Connector With SMP Female Interface

Lightweight Beryllium Bronze RF Coaxial Connector With SMP Female Interface

Model: SMP-KB2-2

Product Overview

The SMP series is an ultra-miniature, push-on/self-locking RF coaxial connector designed for high-frequency and high-density modular applications. Made with high-performance beryllium bronze, this SMP female connector offers superior elasticity, conductivity, and mechanical reliability. Its design allows limited axial and radial float, enabling blind mating in space-constrained environments.

Applications
Widely used in radar systems, antennas, test and measurement equipment, quantum computing, and other applications requiring lightweight, high-frequency, and vibration-resistant RF connections.

Key Features

•     SMP female interface compatible with 2# semi-rigid or semi-flexible coaxial cables
•     Compact and lightweight, ideal for dense system integration
•     High-frequency performance with excellent electrical characteristics
•     Easy to solder and integrate into modular assemblies
•     Strong vibration resistance and mechanical stability
•     Suitable for blind-mate applications with axial/radial misalignment tolerance
