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
