What is an MBX Coaxial Connector?
The MBX coaxial connector (Micro Bayonet X) is a type of RF connector designed for quick, secure mating with excellent shielding against electromagnetic interference (EMI) and radio-frequency interference (RFI). It combines the fast-connect feature of SMB connectors with the ruggedness of threaded connectors, making it a versatile option for demanding environments.
Key characteristics include:
Bayonet coupling mechanism for fast and reliable connections
50 Ohm impedance standard for optimal signal transmission
Compact size suitable for space-constrained circuit boards and cable assemblies
High vibration and shock resistance for use in harsh conditions
