Rosenberger Dual HFM to Waterproof FAKRA Z Cable
This cable series connects a Rosenberger dual cavity HFM Mini FAKRA interface with waterproof FAKRA Z or another compatible dual HFM connection. It gives automotive engineers several connector layouts without forcing every installation into the same cable direction.
The dual HFM side is available in horizontal and vertical configurations, while waterproof FAKRA male and female options cover different mating requirements. Standard cable lengths include 0.5 m, 1 m, 2 m and 3 m.
The compact paired interface is useful in automotive electronics where two coaxial connections need to stay together and installation space matters. Typical projects include camera systems, ECUs, telematics hardware, antenna modules and vehicle development platforms.
Two Coaxial Connections in One HFM Interface
The dual cavity HFM design keeps two coaxial connections together in one compact connector housing. This can make the connector area easier to manage on cameras, ECUs and other automotive electronic modules where available space is limited.
Horizontal and vertical HFM versions address another practical issue: cable exit direction. The best orientation depends on where the mating port sits and how the cable needs to leave the module.
Before ordering, confirm the HFM orientation, connector gender, mating interface and required cable length. A connector that looks similar may not be the correct mating version.
Horizontal Dual HFM Female to Waterproof FAKRA Male
This configuration combines a horizontal dual HFM female interface with a waterproof straight FAKRA male connection.
The horizontal HFM layout is practical when the mating port sits along the edge of an ECU, camera controller or electronic module and the cable needs to leave in the corresponding direction.
Choose this version when both the HFM orientation and FAKRA mating gender match the actual equipment.
Horizontal Dual HFM Female to Waterproof FAKRA Female
This version keeps the horizontal dual HFM female layout but changes the opposite end to a waterproof straight FAKRA female connector.
It is intended for equipment where the installation direction suits the horizontal HFM arrangement but the FAKRA mating port requires the opposite gender from Version 1.
Check the FAKRA mating connector on the camera, ECU, antenna module or existing harness before selection.
Vertical Dual HFM Female to Waterproof FAKRA Male
The vertical version pairs a vertical dual HFM female interface with a waterproof straight FAKRA male connector.
Its different HFM orientation can be useful where the connector position, enclosure or nearby components make a horizontal cable exit inconvenient.
It provides another routing choice without changing the basic dual HFM to FAKRA connection architecture.
Vertical Dual HFM Female to Waterproof FAKRA Female
This configuration combines the vertical dual HFM female arrangement with a waterproof straight FAKRA female termination.
It suits installations where the vertical HFM orientation works with the module layout and the opposite device presents the corresponding FAKRA male mating interface.
Orientation and gender should both be checked rather than selecting the cable from connector appearance alone.
Horizontal Dual HFM Female to Horizontal Dual HFM Female
This version keeps both ends within the dual HFM connector family, using a horizontal female configuration at each end.
It is useful when two compatible HFM equipped modules need to be linked without transitioning to a separate FAKRA interface.
The same orientation at both ends can also make routing more straightforward when the two mating interfaces follow a similar module layout.
Vertical Dual HFM Female to Vertical Dual HFM Female
This cable uses a vertical dual HFM female interface at both ends for compatible equipment designed around the same connector arrangement.
It can be used for module extension, prototype wiring or paired coaxial connections where both mating ports favor the vertical HFM layout.
Keeping the connection inside the HFM family avoids adding an unnecessary intermediate connector type.
Vertical Dual HFM Female to Horizontal Dual HFM Female
This mixed orientation cable uses a vertical dual HFM female connector at one end and a horizontal dual HFM female connector at the other.
It is a useful option when two compatible modules use the same dual HFM connector family but their mounting positions call for different cable exit directions.
Instead of twisting the installation around one fixed orientation, the cable can follow the physical layout of the two connected devices.
Typical Applications
Built Around the Installation
Dual Cavity HFM
Two coaxial connections share one compact HFM housing, helping keep paired interfaces organized around the module.
Horizontal or Vertical
Two HFM orientations help the cable follow different connector positions, enclosure layouts and cable exit directions.
Waterproof FAKRA Options
Male and female waterproof FAKRA configurations can be selected according to the mating connector already used by the equipment.
0.5 m to 3 m
Four standard lengths cover short module connections, general vehicle wiring and longer prototype routing.
Why This Dual HFM Cable Series Is Practical
● Two Coaxial Lines Stay Together
The dual cavity housing keeps two related coaxial connections together instead of placing two separate connector housings around the module.
● Cable Direction Can Follow the Hardware
Horizontal and vertical HFM options make it easier to work around the actual ECU position, enclosure space and cable exit direction.
● Match the Existing Mating Port
Different FAKRA genders and HFM combinations let the assembly follow the interfaces already present on the equipment rather than adding unnecessary adapters.
● Useful from Prototype to Vehicle Integration
The same product family can cover short development connections, ECU integration and longer vehicle routing by changing orientation, termination and cable length.
Why Use a Dual Cavity HFM Connector?
The idea is straightforward: two coaxial connections can be grouped into one compact connector housing.
This becomes useful on automotive electronic modules where connector space is limited and two related coaxial paths need to arrive at the same device.
The paired housing can also make cable identification and routing easier because the two connections remain together rather than being handled as separate loose connectors.
When replacing an existing cable, confirm the connector P/N, cavity arrangement, orientation and mating interface. Similar size does not automatically mean two HFM connectors are interchangeable.
Horizontal or Vertical HFM: Which One Should I Choose?
The difference is mainly about how the connector mates with the equipment and where the cable needs to go after leaving the port.
Horizontal HFM: Choose this version when the mating connector and available cable path correspond to the horizontal arrangement.
Vertical HFM: Useful when the equipment interface or surrounding installation space requires the alternative connector orientation.
If you are replacing an existing harness, the safest starting point is the original connector P/N or a clear photo showing the mating interface and cable exit direction.
Choosing the Right Cable Length
| Length | Suggested Use |
|---|---|
| 0.5 m | Short ECU, camera or module connection |
| 1 m | General automotive prototype and equipment wiring |
| 2 m | Extended module connection and in vehicle routing |
| 3 m | Longer prototype vehicle or equipment routing |
Product FAQ
Is Dual HFM the same as a standard single Mini FAKRA connector?
No. The dual HFM configuration places two coaxial connections within one paired connector housing.
Should I choose horizontal or vertical HFM?
Match the orientation to the mating connector and cable exit direction on the actual module. If replacing an existing cable, check its connector P/N first.
How do I know whether I need FAKRA male or female?
Check the mating connector on the camera, ECU, antenna module or vehicle harness. A clear interface photo or connector P/N can also be used for confirmation.
Can I replace a horizontal HFM cable with a vertical version?
Do not assume they are interchangeable. The mating interface, connector arrangement and available cable exit direction should all be checked.
Does the dual HFM connector carry two coaxial connections?
Yes. The dual cavity design groups two coaxial connection paths within one connector housing.
Which cable length should I choose?
Choose according to the real routing path rather than straight line distance. Standard options are 0.5 m, 1 m, 2 m and 3 m.
Can you make a connector combination not shown here?
Yes. Send the connector or mating P/N, required orientation, opposite connector, cable length, application and quantity for configuration review.
