All SSMB Connector

SSMB Plug Connector

SSMB Jack Connector


SSMB connector are a minimized version of the standard SMB connector with snap-on mating design. This latching design allows easy installation and permits rapid connection and disconnection in small space especially in inaccessible working environment.

SSMB connector have 50 ohm impedance. These SSMB connectors are mainly used in miniaturized high frequency coaxial modules in subminiature devices at frequency up to 3 GHz and for internal equipment cable connections.
