Advanced Four Channel Male Hub for Electronic Control Units
The standout mechanical configuration of this harness lies in its specialized ECT 818B92066A master male interface block. Featuring a precise array of four high frequency center conductor pins within a unified black protective shroud, this plug is built to couple with a corresponding female docking receptacle on main vehicle domain controllers or camera processor modules. This rigid multi pin setup avoids improper alignment issues during assembly plant installation, creating a reliable mechanical junction that stands up to severe vehicle vibration and shock.
The robust perimeter locking tab on the male housing ensures a tight click style engagement that prevents accidental backing out or terminal loose contact. Precision manufacturing ensures the center conductor pins provide uniform contact force and exact alignment with female receptors on the opposing vehicle harness. This robust layout maintains an exact 50 ohm impedance throughout the main coupling junction, eliminating physical gaps that could lead to signal distortion or high return loss during high bandwidth operations.

Channel Routing and Multi Vision Distribution
This multi channel coaxial wire harness optimizes vehicle sensor wiring by grouping four separate high speed video feeds into a single compact master trunk interface. The central ECT male plug connects to the processing unit or central gateway, while the four shielded branches extend outward to hook up individual surround view vision modules or side mirror cameras. This structural separation cleans up messy engine bay layouts, providing a clean cabling framework that fits nicely within tight chassis channels.
Each individual branch wire consists of high grade RTK031 coaxial cable to guarantee top tier electromagnetic compatibility under complex vehicle environments. The dense braided shielding layer blocks external ambient electromagnetic noise and internal channel to channel cross talk, keeping the high frequency data streams totally isolated. This premium shielding configuration secures low latency signal transmission, allowing electronic control units to process flawless high definition video inputs without screen flicker or noise.
Product FAQ
Q1: Can I request different customized branch lengths for the four Rosenberger female outputs ?
A: Yes. Although we supply standard uniform lengths from 0.1 meter up to 5 meters, our factory fully supports custom wire harness manufacturing. You can provide your exact vehicle routing layout to order unique segment lengths for each Rosenberger 59Z163-003Z branch line.
Q2: Are both the master plug and the female branch connectors fully waterproof ?
A: Yes. The main ECT 818B92066A four cavity male plug and the four separate Rosenberger 59Z163-003Z straight female connectors feature integrated high grade sealing rings that achieve strict IP67 waterproof certification, making them qualified for harsh exterior automotive mounting exposed to rain and moisture.
Q3: What is the benefit of the Z Code configuration on the Rosenberger branch connectors ?
A: The Rosenberger 59Z163-003Z connectors use the standard universal Z Code designation. This neutral keying design allows them to connect mechanically with any standard colored Fakra male pins on the camera module side, providing wide hardware compatibility and simplifying assembly line installation.
Q4: Is the master ECT 818B92066A connector a male plug or a female jack ?
A: This model implements a standard male plug configuration containing internal center pins. It is engineered to pair with a matching female four cavity housing receptacle on your device side. Please double check your control module panel layout before submitting your order details.
Q5: Can this high speed coaxial harness support high frequency GMSL camera streams ?
A: Absolutely. The integrated RTK031 high frequency wire is fully optimized to meet modern high bandwidth automotive parameters, offering an ideal equivalent for Dacar302-4 and ECT302LL lines. It perfectly maintains low signal loss for Gigabit Multimedia Serial Link and FPD Link camera system protocols.
