Twinax Connectors Amphenol RF Twinax Connectors are used with 78Ω and 95Ω conductor cables and operate from 0MHz to 200MHz. Due to the improved shielding characteristic (>,30dB), these connectors are used in balanced low level and high sensitivity circuits. Amphenol RF Twinax Connectors meet the applicable sections of MIL-DTL-3655. They feature keyway polarization to ensure system integrity and prevent signals from being mixed. These connectors are ideal for computer network applications.
