Coaxial Contacts
SHIELDED COAXIAL CONTACT
These contacts are required for high frequency interconnection. High speed Coax contacts within a connector provide the shielding protection in order to eliminate interferences from outside electrical sources, and many cases the RF/Microwave performance needed in the circuitry of many applications.
FEATURES AND BENEFITS Large crimping area assures low contact resistance and high tensile strength Back insulator provides closed entry for socket inner contact against axial loads Front insulator provides closed entry for socket inner contact Recessed inner contact is protected Outer contact has rugged wall section for durability
MATERIALS AND FINISH Body: Copper alloy Finish: Gold over nickel on mating parts Insulators: High Performance Fluorocarbon

GUIDELINE TO CHOOSE THE RIGHT COAXIAL CONTACT Choose the contact application : Standard Frequency, High Frequency or very high Frequency Standard Frequency: Non Impedance Matched Contacts ( VSWR: 1.5:1) High Frequency: Impedance Matched Contacts (VSWR: 1.2:1 +.04F (GHz) up to 3GHz) Very High Frequency: BMA / BMZ Interface contacts
Check the cable diameter versus the contact size : Sometimes we can use a smaller contact Sometimes the wire is bigger than the contact
