Plug-to-Jack HFM Extension Cable
The AMK14K-1M4Z5-Z to AMS14D-1M4Z5-Z cable assembly is a four-port HFM Mini FAKRA Z-code extension cable designed to extend or reposition an existing automotive coaxial connection. One end uses a Rosenberger AMK14K-1M4Z5-Z jack, while the opposite end uses an AMS14D-1M4Z5-Z plug.
Unlike a jack-to-jack equipment interconnect, this complementary plug-to-jack configuration can be inserted into an existing compatible HFM link without changing the connector family or the four individual coaxial signal paths. It is suitable for prototype integration, module relocation, test access, service work and harness-routing adjustments.
The standard assembly uses LEONI DACAR 302-4 automotive coaxial cable and provides four straight-through 50-ohm channels. Standard lengths are 0.5 m, 1 m and 2 m, with custom lengths available after confirmation of the complete link and application requirements.
Connector-End Definition
| Interface Item | P1 End | P2 End |
| Connector Part Number | Rosenberger AMK14K-1M4Z5-Z | Rosenberger AMS14D-1M4Z5-Z |
| Interface Form | 4-port HFM Mini FAKRA jack | 4-port HFM Mini FAKRA plug |
| Connector Coding | Z Code | Z Code |
| Protection | IP67 when correctly mated | IP67 when correctly mated |
| Connection Function | Receives the corresponding HFM plug interface | Mates with the corresponding HFM jack interface |
Both ends contain four separate coaxial interfaces. This product should therefore be described as a four-port or four-channel coaxial cable assembly rather than a conventional four-pin electrical cable.
When an HFM Extension Cable Is Required
A plug-to-jack extension cable can be used when the original HFM connection does not provide sufficient routing length or when a connected module must be moved without replacing the complete vehicle or equipment harness.
| Installation Situation | Extension-Cable Function |
| Module relocation | Adds routing length between the original harness and the connected camera, display or control module. |
| Prototype vehicle integration | Allows temporary equipment positioning during development, installation and validation. |
| Bench testing | Brings the HFM interface to a more accessible location for test and measurement work. |
| Service access | Provides additional working length when inspecting, diagnosing or replacing connected modules. |
| Harness-routing correction | Compensates for an installation route that is longer than the original cable connection allows. |
Straight-Through Channel Continuity
The standard PCM-ZC-0196 construction maintains direct channel continuity between the jack and plug interfaces. Each coaxial center conductor and its corresponding shield are routed independently through the extension.
| P1 Jack Channel | P2 Plug Channel | Standard Connection |
| Pin 1 center and shield | Pin 1 center and shield | Straight-through |
| Pin 2 center and shield | Pin 2 center and shield | Straight-through |
| Pin 3 center and shield | Pin 3 center and shield | Straight-through |
| Pin 4 center and shield | Pin 4 center and shield | Straight-through |
The cavity positions appear mirrored when the mating faces of the plug and jack are viewed from the front. Production and inspection must follow the numbered connector cavities and approved drawing rather than visual left-to-right position alone.
Specified Assembly Performance
| Parameter | Drawing Requirement |
| Internal Product Series | PCM-ZC-0196 |
| Cable | LEONI DACAR 302-4 automotive coaxial cable |

| Nominal Impedance | 50 Ohm |
| Specified Frequency Range | DC to 6 GHz |
| VSWR | 1.80 Max. |
| Dielectric Withstanding Voltage | 800 VRMS Min. |
| Cable Retention | 110 N Min. |
| Operating Temperature | -40°C to +105°C |
| Production Inspection | 100% continuity test |
Length Selection and Installation
Extension length should be limited to the distance required by the installation. Adding cable and an additional mated connector pair changes the complete transmission path and may affect insertion loss, return loss and available signal margin at higher frequencies.
| Part Number | Nominal Length | Typical Selection Purpose |
| PCM-ZC-0196-0.5M | 500 ± 15 mm | Short module relocation or test access |
| PCM-ZC-0196-1M | 1000 ± 20 mm | General extension and prototype routing |
| PCM-ZC-0196-2M | 2000 ± 20 mm | Longer bench or vehicle-development connection |
The complete installation should be reviewed for total link length, operating frequency, routing radius, available connector clearance and environmental exposure. Protocol-level performance must be validated in the finished customer system.
