SSMB-Nano

The SSMB-Nano connectors are a minimized version of the standard SMB connector and incorporate a 'snap-on' latching action or a 'slide-on' coupling for ease of connection. Due to extremely precise manufacturing tolerances this range of connectors is suitable for use at high operational frequencies.

This connector range is suitable for the standard ranges of flexible and semi rigid cables and is also available in PCB and panel mount versions.

The characteristic impedance of the SSMB-Nano coaxial connectors is 50 ohm.

SSMB-Nano coaxial connectors meet the specification of IEC 169-19.
