The Amphenol RF 920-515P-51A is an HD-EFI series plug, male pin, built for 50 Ohm coaxial signal paths. The 50 Ohm impedance matches the standard RF system impedance for most wireless and telecom applications, so the connector presents a controlled characteristic impedance to the line. Rated to 6 GHz maximum frequency, it covers common cellular bands (LTE, 5G sub-6 GHz), Wi-Fi 6E, and ISM-band links without a significant impedance discontinuity at the interface. The snap-on fastening gives a quick, positive lock during mating — the coupling ring clicks into place, which is typical for HD-EFI connectors used in panel-mount applications where the cable assembly is frequently connected and disconnected. With 200 mating cycles rated, it's suited for field-serviceable equipment like base station antenna ports or test points, though not for high-cycle production test racks.
Complete Termination Kit for 1.13 mm Coaxial Cable
The kit is designed for 1.13 mm coaxial cable — a common micro-coax size used in compact RF assemblies for IoT modules, GNSS antennas, and internal device wiring. The end cap covers the crimp area for strain relief and environmental protection.
Panel Mount, Right Angle — Saves Depth in Tight Enclosures
The panel mount uses a snap-on retention ring (not threaded), so installation is tool-less: push the connector through the panel cutout until the snap ring seats. The body is beryllium copper and brass with gold and nickel finish, giving good conductivity and corrosion resistance for the RF path.
Wide Temperature Range and Materials for Harsh Environments
The dielectric is PTFE, which maintains stable electrical properties across that range.
