SMA Female RF Coaxial Connector – Slotted, Flange Mount Socket, 18GHz
SMA Female RF Coaxial Connector – Slotted, Flange Mount Socket
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
