SMP Male RF Coaxial Connector – Limited Detent, Microstrip Type, Flange Mounted
Product Overview
The SMP series is a next-generation blind-mate RF coaxial connector designed for high-frequency, high-reliability applications. With a compact push-on interface and limited detent (moderate retention force), it allows for axial and radial float, making it ideal for blind mating in densely packed modular systems such as between printed circuit boards, chassis, and enclosures.
Applications
Ideal for high-density RF systems including communication base stations, matrix antennas, radar systems, aerospace modules, and other environments where fast, secure, and vibration-resistant connections are essential.
Key Features
Limited detent interface for secure yet easily detachable blind-mating
Microstrip-compatible design for efficient PCB transitions
Two-hole flange mounting for stable mechanical installation
Supports high-frequency performance with excellent signal integrity
Compact size, strong seismic resistance, and easy soldering
Complies with relevant MIL and IEC standards for RF connectors
