HD-EFI Micro-Miniature Interface Connectors

Amphenol RF HD-EFI Series Micro-Miniature Interface Connectors are designed to allow large board tolerance stack-ups, blind mating, and multiple RF lines. These products maximise radial and axial float while maintaining high-frequency RF performance. HD-EFI PCB jacks are available in through-hole, surface-mount, and edge-launch designs. The three-piece mating system uses a limited detent and a smooth bore PCB connector, joined by a floating bullet adapter in between. The generous gathering cone and unique bullet design allows for 1.4mm of axial float, and 1.4mm of radial float, with a maximum float angle of 5 degrees.
