SMB Dual-Crimp Cable Plugs
These SMB plugs feature crimp center contacts for fast assembly, with
reduced size and weight compared to standard SMB cable plugs.
Other features include:
• 50 ohm or 75 ohm impedance.
• For single or double-shielded cables.
• Gold-plated captive contact.
• Nickel plated body and crimp sleeve.
• Fast delivery from stock.
