The SMB connectors incorporate a SMB 'snap on' latching action for ease of connection. 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 SMB coaxial connectors is SMB 50 or 75 ohm. The 75 ohm version is also known as SMZ coaxial con- SMZ nector. SMB coaxial connectors (50 ohm) SMB meet the specification of IEC 169-10 and MIL-C-39012. SMZ coaxial connectors (75 ohm) SMZ meet the specification of IEC 169-28. Read more at: www.imscs.com
