SMB Type RF Connector FAQs
QWhat is the difference between SMA and SMB connectors?
QWhat is the difference between SMA and SMB connectors?
SMB connectors are more compact than SMA types. SMAs feature a threaded coupling offering superior vibration resistance. SMBs use a quick snap-on coupling, ideal for easier connections in space-constrained areas where vibration is less critical. You might also be interested in these other compact connector families:
