SMB & SMC Coaxial Connector - Gender Explained

We are often asked what is the correct gender scheme of the SMB and SMC coaxial connector.


Unlike more common coaxial connectors such as BNC, N, SMA, UHF, etc.  The SMB and SMC connectors do not utilize the standard gender scheme.  Typically speaking a coaxial plug refers to a male center pin and the coaxial jack refers to a female center hole; however, this configuration does not apply to SMB and SMC connectors.


The SMB and SMC coaxial connector has a non-conventional gender system.  The SMB and SMC plug has a female center hole and the SMB and SMC jack has male center pin.
