Version 1

H-MTD x2+6P to H-MTD x2+6P Cable

This version connects H-MTD x2+6P interfaces at both ends, providing a direct extension for two independent high-speed data channels together with six auxiliary contacts. It is suitable for extending connections between compatible vehicle modules without changing the original interface architecture.

Cable length and auxiliary wiring can be customized according to the system layout, making it suitable for ECU relocation, prototype vehicle wiring, HIL test benches and dual-channel Automotive Ethernet extension.

Version 2

H-MTD x2+6P to 2× H-MTD Female Cable

This breakout cable converts one H-MTD x2+6P interface into two individual H-MTD female connectors, allowing the two high-speed channels to be routed separately to different vehicle devices.

The two-branch design provides flexible installation when cameras, sensors or ECUs are located in different positions. Branch lengths can be customized for ADAS integration, ECU development, prototype harnesses and distributed vehicle network connections.

Version 3

H-MTD x2+6P to 2× H-MTD Male Cable

This configuration breaks out the H-MTD x2+6P interface into two H-MTD male connectors, providing separate access to each high-speed data channel for vehicle-side equipment and engineering test systems.

The male interfaces are well suited for connection with compatible ECU ports, test fixtures and validation equipment. Typical uses include HIL testing, ECU debugging, Automotive Ethernet measurement and laboratory network validation.

Version 4

H-MTD x2+6P to 2× MATEnet Female Cable

This version routes the two high-speed channels from an H-MTD x2+6P interface to two separate MATEnet female connectors, providing an efficient transition between H-MTD and MATEnet based vehicle networks.

Each MATEnet branch operates as an independent connection, making the cable suitable for systems using different Automotive Ethernet connector families. It is ideal for domain controller integration, ADAS development, mixed-interface prototypes and network adaptation.

Version 5

H-MTD x2+6P to 2× MATEnet Male Cable

This configuration combines one H-MTD x2+6P interface with two MATEnet male connectors, providing two independent data paths for connecting MATEnet-equipped modules within mixed-interface vehicle networks.

The male breakout design offers an alternative mating configuration for specific ECU and equipment interfaces. Cable length, branch length and auxiliary wiring can be customized for vehicle gateway integration, ECU interconnection, prototype network routing and Automotive Ethernet interface conversion.

Application Scenarios

Typical Applications

ADAS Sensor Network Integration

Routes two independent high-speed data channels to cameras, radar, LiDAR or other ADAS modules through H-MTD or MATEnet breakout connections.

HIL & ECU Validation

Provides separate access to both high-speed channels for ECU debugging, signal measurement and hardware-in-the-loop testing with flexible breakout interfaces.

Mixed-Interface Vehicle Networks

Supports vehicle systems using both H-MTD and MATEnet interfaces, enabling flexible dual-channel connections between domain controllers, ECUs and development modules.

Product Features

Dual High-Speed Channels in One Connector

The H-MTD x2+6P architecture integrates two independent differential data channels into one compact connector, supporting space-efficient high-speed connectivity for modern vehicle electronics.

Five Flexible Interface Configurations

Available with H-MTD x2+6P, dual H-MTD or dual MATEnet outputs, with male and female breakout options to match different ECU, controller and test-system interfaces.

Core Benefits

Product Advantages

Reduced Harness Complexity

Combines multiple connection paths into a more organized harness architecture, helping reduce separate cable runs and simplify wiring around ECUs, domain controllers and test platforms.

Easier System Upgrades

Allows existing vehicle network equipment to connect with different interface layouts without requiring major changes to the surrounding harness, making prototype revisions and system upgrades easier to manage.

Faster Installation & Maintenance

Clearly separated branches make individual device connections easier to identify, install and replace, reducing handling time during vehicle assembly, troubleshooting and laboratory work.

Project Ready Customization

Multiple standard lengths from 0.5 m to 5 m are available, with custom cable length, branch dimensions and wiring arrangements supported for different installation layouts and project requirements.

Connection & Ordering Notes

For 99K1HG-1CAZ5-Z H-MTD x2+6P cable assemblies, the mating interface, coding and pin assignment should be confirmed before production to ensure correct system integration.

Confirm H-MTD or MATEnet breakout interface and connector gender.
Verify mating connector, coding and cable requirements.
Define the 6 auxiliary contact pin assignments according to the project.
Confirm cable length and branch length before ordering.

For frequent connection or disconnection, operate the connector through its locking mechanism rather than pulling the cable to help protect the termination and maintain reliable mating.

WHY H-MTD x2+6P FOR MODERN VEHICLE NETWORKS?
