Dual Port H-MTD Power Pin Automotive Cable

Dual Port H-MTD+6, Z Code, Female Jack, 99K1HG-1CAZ5-Z

100Ω Nominal

●    Integrated Data, Power and Auxiliary Signal Transmission

The P1 end employs the Rosenberger 99K1HG-1CAZ5-Z dual-port H-MTD+6 modular connector head, which integrates 6-pin MQS contacts onto the H-MTD automotive Ethernet data interface. The H-MTD channel is responsible for high-speed data communication, while the MQS return path consists of 2-core 20AWG power lines and 4-core 22AWG signal lines, which can be used for device auxiliary power supply, control, detection, or state feedback. Multiple electrical functions are concentrated at the same connector end, helping to reduce the number of separate power plugs, control interfaces, and wiring harnesses, resulting in a more compact and clear layout around the vehicle's equipment.

●    Function-Specific Automotive Wire Configuration

The MQS section uses a mixed-gauge configuration selected for different electrical functions. Two 20AWG conductors are assigned to auxiliary power circuits, providing a larger conductor cross-section to help reduce resistance and voltage drop over the cable run. Four 22AWG conductors are available for auxiliary data, control or sensing signals. Keeping power and auxiliary signal circuits on separate conductors supports application-specific pin assignments and simplifies electrical testing, fault identification and future harness servicing.

●    Genuine Rosenberger Z-Coded Mating Interfaces

The wiring harness employs Rosenberger's original H-MTD series connectors: the P1 end features a 99K1HG-1CAZ5-Z dual-port H-MTD+6 Z coding female connector, while the P2/P3 ends have an E6S10A-1CAZ5-Z 2-pin H-MTD Z coding male connector. The corresponding male-to-female configuration enables clear interface compatibility, with the Z coding mechanical positioning aiding in identifying the correct insertion direction, thereby reducing the risk of misinsertion, incorrect insertion, or mixed interface usage during assembly. The straight-line wiring structure is suitable for axial wiring between vehicle equipment, central gateways, domain controllers, and camera modules.

●    Dedicated High-Speed Channel and Shielded Transmission

The automotive Ethernet channel uses GG 2Speed 251 high-speed cable and remains electrically separate from the 6-pin MQS power and auxiliary signal conductors, helping reduce direct coupling between circuits with different functions. Its shielded construction helps suppress electromagnetic interference generated by motors, DC/DC converters, switching power supplies and densely routed vehicle harnesses, supporting improved signal integrity and communication stability. The dedicated data path also simplifies continuity, short-circuit, pin-assignment and transmission-performance testing during production.
