Waterproof 4 in 1 Mini FAKRA to FAKRA Cable
As ADAS, surround-view cameras, e-mirrors, smart cockpits and connected-vehicle systems continue to add high-speed coaxial links, vehicle architectures must accommodate more camera and RF connections while addressing connector space, harness routing and reliable connectivity in environments exposed to moisture, dust and vibration.
Premier Cable's TE waterproof 4-in-1 Mini FAKRA to FAKRA automotive coax cable uses a TE 2-2354439-9 series four-channel sealed Mini-FAKRA interface on the main side. Four coaxial connections are consolidated into a compact multi-port architecture and then broken out into four independent waterproof FAKRA interfaces.
The series is available in two primary configurations:
1. TE Waterproof 4-in-1 Mini FAKRA Female → 4 × Waterproof FAKRA Female
2. TE Waterproof 4-in-1 Mini FAKRA Female → 4 × Waterproof FAKRA Male
The primary function is not protocol conversion. Instead, the cable assembly provides physical interface adaptation and harness-topology conversion between a multi-port Mini-FAKRA interface and individual FAKRA connections while maintaining four independent coaxial paths.
Waterproof 4-in-1 Mini FAKRA Female to FAKRA Female Cable
This configuration uses a TE 2-2354439-9 series sealed four-channel Mini-FAKRA interface as the consolidated connector and breaks it out into four independent waterproof FAKRA female interfaces.
It is suitable for harness architectures in which the destination device, camera module, RF module or validation system requires female FAKRA connections. Compared with using multiple separate adapters, an integrated four-channel breakout harness reduces intermediate connection points and makes individual coax channels easier to identify, route and manage.
For ADAS validation benches, camera ECUs, domain-controller testing or customized vehicle harnesses, the coding, cable length and channel mapping of each branch can be configured according to the actual equipment interface.
Waterproof 4-in-1 Mini FAKRA Female to FAKRA Male Cable
The second configuration retains the same four-channel sealed Mini-FAKRA main interface while using four waterproof FAKRA male connectors on the breakout side.
Its main value appears in projects requiring a different mating-interface gender. FAKRA male branches can be selected directly according to the camera, ECU, antenna module, deserializer board or test-equipment interface without adding separate gender changers.
Because automotive FAKRA selection involves not only male/female gender but also coding, mechanical keying and cable compatibility, the exact equipment-side part number should be verified before production rather than selecting an interface by color or appearance alone.
Typical Applications
Product Features
Four-Channel Consolidated Coax Interface
Four independent coaxial paths are consolidated into one multi-port Mini-FAKRA interface, helping reduce connector-area requirements and simplify harness routing around ECUs, camera controllers and automotive electronic modules.
Sealed Connector Architecture
Sealable Mini-FAKRA and FAKRA architectures support harness development for installation areas exposed to moisture, dust or demanding vehicle environments. Final harness protection ratings should be validated based on connectors, seals, cables and assembly processes.
Four Independent Breakout Channels
The four FAKRA branches can correspond to separate camera, antenna or ECU channels, with customizable branch lengths, labels and channel identification for easier vehicle assembly and service.
Selectable FAKRA Gender
The FAKRA side can be configured with female or male interfaces according to the target device, allowing direct mating-interface matching and reducing the need for additional gender adapters.
Product Advantages
● Fewer Intermediate Connections
An integrated Mini-FAKRA-to-FAKRA harness reduces the additional mating points introduced by multiple standalone adapters, simplifying both the system BOM and installation path.
● Designed for High-Density Vehicle Architectures
The consolidated four-channel structure is well suited to camera ECUs, ADAS controllers and zonal architectures where connector counts are increasing while installation space remains limited.
● Greater Harness Engineering Flexibility
FAKRA gender, coding, overall length, individual branch lengths, cable type, labels and channel mapping can be engineered around project requirements for OEM, Tier 1 and validation-equipment applications.
● Better Suited to Demanding Installation Areas
Compared with conventional unsealed adapters, a sealed interface architecture is better suited to installation areas potentially exposed to moisture, splash and contaminants, while final waterproof performance should still be validated under the intended application conditions.
Why Use 4-in-1 Mini-FAKRA Instead of Four Separate FAKRA Interfaces ?
Traditional FAKRA connections are generally arranged as individual coaxial channels. When an ADAS ECU connects to multiple cameras, several separate interfaces may therefore be required.
A four-channel Mini-FAKRA architecture consolidates multiple coaxial channels into a compact housing, reducing connector-area requirements and creating a more organized multi-camera harness.
However, "4-in-1" does not mean that four signals are electrically combined. They remain separate coaxial channels within the cable assembly.
↕ Select FAKRA Male or Female Based on the Device Interface
First verify the actual mating interface of the camera, ECU, antenna module or test equipment. Select the 4-in-1 Mini-FAKRA female to 4× FAKRA male version when male FAKRA interfaces are required, or choose the 4-in-1 Mini-FAKRA female to 4× FAKRA female version when female FAKRA interfaces are required. Do not determine gender by appearance alone; verify the exact device-side part number.
□ Verify Coding and Channel Mapping for All Four Channels
The four FAKRA branches may connect to front cameras, rear cameras, surround-view cameras, GPS/GNSS modules or other automotive devices. Therefore, specify the FAKRA coding, mechanical keying and channel mapping for every branch. For GMSL or FPD-Link camera links, each channel should also correspond correctly to the designated ECU port rather than being selected by housing color alone.
◉ Define Cable, Length and Sealing Requirements for the Application
After defining the interfaces, select the appropriate cable type, overall length, branch lengths and sealing requirements for the installation environment. ADAS camera and high-speed SerDes applications should evaluate impedance, frequency range, insertion loss and link budget. For locations exposed to moisture, dust or splash, verify that the connectors, seals, cable and completed assembly meet the required environmental protection standards.
Product FAQ
Is 2-2354439-9 a Standard FAKRA Interface ?
No. This cable architecture connects a TE four-channel Mini-FAKRA / MATE-AX consolidated interface to individual FAKRA branches. Mini-FAKRA / MATE-AX and conventional FAKRA differ significantly in mechanical structure, interface size, and channel integration density.
Does This Cable Harness Combine Four Signals into One ?
No. "4-in-1" describes four interfaces consolidated within one housing; it does not mean that the four signals are combined. The four coaxial paths remain independent and connect individually to their corresponding FAKRA branches.
Does Mini-FAKRA to FAKRA Require Protocol Conversion ?
Normally no. This is a passive coaxial cable assembly designed primarily for physical-interface adaptation and coaxial signal connectivity between Mini-FAKRA and FAKRA. It does not contain an active SerDes, PHY, or protocol-conversion IC.
Can It Be Used for GMSL or FPD-Link ?
The assembly can be engineered for automotive SerDes coaxial links such as GMSL and FPD-Link, but system compatibility cannot be determined by connector type alone. Cable type, operating frequency, insertion loss, return loss, impedance, and the complete SerDes link budget must also be verified.
Can the Four FAKRA Connectors Use Different Codings ?
Different codings can be assigned to the four FAKRA branches according to the vehicle interface architecture, helping distinguish individual channels and reduce mismating risks. However, the mechanical key, housing, gender, and exact part number of each target device must be confirmed rather than relying on housing color alone.
