Product Overview
The SMP series is an ultra-miniature, push-on/self-locking RF coaxial connector system known for its compact size, lightweight construction, broad frequency range, and strong vibration resistance. The limited detent interface allows for secure yet easily detachable blind mating, making it especially well-suited for high-density modular connections between PCBs, chassis, and enclosures.
Applications
Commonly used in antennas, communication base stations, radar systems, aerospace electronics, and other compact, high-performance RF assemblies.
Key Features
SMP male interface with limited detent (moderate retention force)
Two-hole flange mount for secure and stable installation
Compatible with coated CXN3506 RF coaxial cable
Small size and lightweight, ideal for dense system integration
Wide frequency bandwidth with excellent electrical performance
Strong resistance to shock, vibration, and environmental stress
