100 Ohm HSD Fakra Quadraxial Plug — Right Angle PCB Mount
The Amphenol HSDNARPPCB7B is a 1-port HSD Fakra Quadraxial plug with male pin contacts, designed for 100 Ohm differential signal paths in automotive infotainment and camera systems. It belongs to the HSD (High-Speed Data) Fakra connector family, the standard for coaxial and quadraxial links carrying LVDS, USB, or Ethernet signals in vehicle harnesses.
What the 100 Ohm Impedance Means for the Signal Path
The 100 Ohm characteristic impedance is the defining electrical spec for this connector — it matches the differential impedance of the quadraxial cable and the PCB trace pair, minimising reflections at the interconnect. This is not a generic power connector; the impedance control governs the signal integrity for high-speed data links up to several GHz, making it the right choice for a camera-to-ECU or head-unit-to-display link where bit error rate matters. The gold-plated centre contacts support the low and stable contact resistance needed to maintain that impedance over the connector's 25 mating cycles.
Right-Angle Mount and Latch Lock — Board Layout and Retention
This is the orientation for a board-edge I/O connector that plugs into a mating receptacle from the side of the enclosure. The latch lock provides positive mechanical retention — the plug clicks into the mating half and stays mated under vibration, which is the expected duty in an automotive or industrial environment where the harness sees constant movement. The zinc alloy body with tin finish gives the shell the durability to handle the 25 mating cycles without galling on the latch mechanism.
Temperature Range and Dielectric — Built for the Engine Bay
The thermoplastic dielectric maintains its dimensional stability and dielectric properties across that range, so the 100 Ohm impedance stays within tolerance as the connector heats and cools. The black housing colour is the standard Fakra visual identifier for the A-code keying, which prevents cross-mating with other Fakra code variants in a multi-connector harness.
