SMA Female RF Coaxial Connector – Flange Mount, Stainless Steel, 18GHz Frequency Durability

Model: SMA-KFD964G

Product Overview

The SMA series is among the most widely used RF connector types due to its small size, wide frequency bandwidth, and superior mechanical and electrical performance. This 4-hole flange mount version is engineered for reliability in high-vibration and harsh environments, making it ideal for mission-critical systems.

Applications

  •     Aerospace & aviation systems
  •     5G base stations
  •     Precision instrumentation and meters
  •     Automotive and marine electronics
  •     Military and communication infrastructure

Product Features

  •     4-hole flange mount for secure panel installation
  •     Stainless steel housing ensures high strength, corrosion resistance, and thermal stability
  •     Slotted inner conductor (0.5 mm wide, 1.5 mm deep) provides elastic contact, reducing resistance and insertion loss
  •     Uniform point mortise structure enhances grounding and signal integrity
  •     Operates reliably in environments with shock, vibration, and extreme temperatures
  •     Complies with global SMA standards for full interchangeability
