SMZ (75 Ohm SMB)


The SMZ connectors incorporate a '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 SMZ coaxial connectors is 75 ohm.

SMZ coaxial connectors (75 ohm) meet the specification of
IEC 169-28.
