Product Overview
The SBMA series is a new type of low-power blind-mate RF coaxial connector and a miniaturized version of the BMA series. It offers a compact design, high reliability, and is well-suited for the modularization of modern RF systems. Its slide-on interface allows for fast, alignment-free connections, ideal for high-density environments.
Application Scope
Blind mating between chassis and cabinet modules
Modular radar, communication, and electronic systems
High-frequency subsystem integration
Product Features
SBMA male connector with two-hole flange mounting
Compatible with 1# semi-rigid or semi-flexible coaxial cable
Compact size with wide bandwidth support
High mechanical reliability and easy blind connection
Ideal for space-constrained, modular installations
