100 Ohm Quadraxial Plug for HSD Fakra Systems
The Amphenol HSDNCRPPCB12A is a 100 Ohm quadraxial plug from the HSD® Fakra connector family, designed for high-speed data transmission in automotive and industrial applications. This male pin connector uses the Code C keying variant, which prevents cross-mating with other Fakra color codes in a multi-connector harness.
Build and Termination Details
The connector body is a blue thermoplastic housing over a zinc alloy shell with nickel finish. The center contact is a copper alloy with gold plating, terminated by soldering to the PCB. The shield is also soldered to the board, giving a continuous ground path from the cable braid through to the PCB ground plane.
Temperature Range and Operating Environment
The thermoplastic dielectric and zinc alloy shell handle the thermal cycling without cracking or losing contact force. The 100 Ohm differential impedance is maintained across the temperature range, which matters for the signal integrity of LVDS or Ethernet data pairs running through the quadraxial contact set.
