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