The CBJ70TL Twinax/Triax connectors are used when signals require protection form noise through non-signal-carrying shielding. These interfacing connectors must provide contact surfaces isolated from each other and isolated from the outer shield. Trompeter twinax/triax connectors have two concentric contacts that are isolated from each other and the shielding connection. The CBJ70TL are Twinax/Triax TRB Concentric
