What Is a Waterproof H-MTD Automotive Ethernet Cable ?
H-MTD, or High-Speed Modular Twisted-Pair Data, is a high-speed modular differential twisted-pair connector system developed by Rosenberger primarily for automotive high-speed digital communication.
Compared with conventional multi-pin low-speed connectors, H-MTD places greater emphasis on high-speed differential signal integrity, controlled impedance, EMC, modular interface design and high-density installation.
H-MTD uses two signal contacts to form one differential pair and combines them with metallic shielding to create a high-speed differential transmission path.The H-MTD technology platform can support Automotive Ethernet as well as various high-speed SerDes applications. Its value therefore comes not from one individual protocol, but from providing a standardized, high-speed and compact physical interconnection platform for next-generation vehicle networks.
What Is H-MTD Z Code ?
Coding is an important mechanical mismating-prevention feature in automotive high-speed connector design.
Different codings use housing and keying geometries to mechanically distinguish interfaces so that connectors assigned to different functions cannot easily be incorrectly mated.
PCM-ZC-0097 uses water-blue Z coding. When several visually similar high-speed data interfaces are located in the same vehicle area, coding helps assembly personnel, service technicians and automated production equipment identify the correct connection point more accurately.
Therefore, H-MTD cable selection should not be based only on "single port" or "2 pin"; the coding must also be verified.
Pain Points
PCM-ZC-0097
PCM-ZC-0097 uses two Rosenberger E6K14A-1CAZ5-Z waterproof straight H-MTD Z-Code female connectors to create a female-to-female high-speed extension configuration.
Each H-MTD interface contains Pin 1 and Pin 2 high-speed signal contacts forming one differential pair.
The connectors are joined by GG 2Speed 251 FL09YBCY 2×0.14mm² shielded automotive data cable designed around a nominal 100Ω differential impedance.
Through appropriate connector-shell termination, the cable shield establishes an EMC shielding path for the high-speed data link, helping reduce the influence of the vehicle's complex electromagnetic environment on differential data transmission.
Designed for up to 10Gbps-class automotive links, supporting high-bandwidth data connectivity for cameras, sensors, ADAS and central computing.
● 100Ω Impedance & Dual Shielding
100Ω controlled differential impedance with foil and tinned-copper braid shielding helps reduce signal reflections, crosstalk and automotive EMI.
● Waterproof & Wide-Temperature Capability
Waterproof H-MTD interfaces with a -40°C to +105°C design range support moisture, condensation, splash and demanding automotive temperatures.
● Reliable Mechanical Connection
Automotive H-MTD locking with a minimum 110N cable-retention design provides mechanical reliability for vibration, long-term routing and stable connections.

Compatibility Statement
Compatibility Verification
PCM-ZC-0097 uses Rosenberger E6K14A-1CAZ5-Z waterproof H-MTD Z-Code female connectors at both ends, but sharing the H-MTD interface does not ensure interchangeability.
Verify the exact P/N, gender, coding, keying, pin mapping and mating interface, together with 100Ω differential definition, PHY, protocol and data rate. Full compatibility requires mechanical, electrical and system-level matching.
Technical Compatibility Notice
H-MTD is a high-speed differential interconnect system, not a specific communication protocol, so the interface alone does not confirm 10GBASE-T1 or 10Gbps operation. DC–10GHz describes frequency-domain performance, not a 10Gbps data rate.
High-speed links must also consider impedance, PHY, protocol, cable length and link budget, with insertion loss, return loss, mode conversion and signal integrity re-evaluated as cable length increases.
How to Select a Waterproof H-MTD Automotive Ethernet Cable ?
Confirm Exact P/N, Gender and Z Coding
Do not select a cable based only on the term "H-MTD." First confirm the complete Rosenberger P/N of the ECU, camera, radar or switch interface, including jack/plug, male/female configuration, Z coding, waterproof construction and mating interface.
PCM-ZC-0097 uses E6K14A-1CAZ5-Z waterproof female connectors on both ends, so the target equipment must provide the correct mating interface for this version.
Confirm the Target Data Rate According to PHY and Protocol
If the system uses 100BASE-T1, 1000BASE-T1, 2.5GBASE-T1, 5GBASE-T1 or 10GBASE-T1, confirm that the ECUs or switches on both ends use the corresponding PHY.
Do not determine the complete vehicle-system data rate solely from the statement that "H-MTD supports 10Gbps."
The connector, cable and PHY must be evaluated together as a complete channel.
Select 2m, 5m or 10m According to the Link Budget
Cable length affects not only installation space but also high-speed electrical performance.
A 2m cable generally introduces lower cable loss. When the length increases to 5m or 10m, insertion loss, return loss, mode conversion and the channel margin allowed by the PHY should be carefully evaluated.
For high-data-rate applications such as 10Gbps links, system validation using the actual ECU, cable assembly and mating connectors is recommended before volume deployment.
Confirm Waterproofing and Shielding According to the Installation Environment
If the cable is installed in a protected cabin area, environmental protection requirements may be relatively low. If it is routed near the vehicle body, cameras, external sensors or areas exposed to moisture, the waterproof connector, seal, shield termination and cable jacket should be evaluated carefully.
The shielding structure should also be reviewed against the vehicle EMC requirements of the specific project.

Product FAQ
Does PCM-ZC-0097 Always Operate at 10Gbps ?
An absolute conclusion cannot be made based on the cable assembly alone.
PCM-ZC-0097 is designed for automotive high-speed data links up to the 10Gbps class, but the final data rate is determined by the ECU PHY, switch PHY, cable length, connectors, mating interfaces and complete channel.
For 5m and 10m versions in particular, link validation using the actual system is recommended.
Does DC–10GHz Mean 10Gbps ?
No.
GHz describes the frequency domain, while Gbps describes the digital data rate. They are not parameters that can be converted directly on a one-to-one basis.
DC–10GHz describes the high-frequency electrical performance range of the product, while actual 10Gbps communication also depends on encoding, PHY characteristics, S-parameters and channel loss.
Can PCM-ZC-0097 Connect to Every H-MTD Interface ?
No.
The complete P/N, gender, coding, housing, keying and mating interface must be verified.
Even if two connectors belong to the H-MTD family, different coding or mechanical structures may prevent them from mating.
Why Use a Waterproof H-MTD Connector ?
Waterproof versions are mainly used in vehicle locations that may be exposed to moisture, condensation, splash or more demanding environmental conditions.
They provide the high-speed data interface with a sealing structure better suited to harsh automotive environments.
Actual IP performance requires the complete mating connector to be properly engaged and used under the specified installation conditions.
Why Does GG 2Speed 251 Use Both Foil and Braid Shielding ?
Foil provides broad high-frequency shielding coverage, while a tinned-copper braid helps create a low-impedance shield path and adds mechanical strength.
Combining these two structures can improve shielding effectiveness in complex automotive EMC environments.
Actual EMC performance still depends on the connector shell, 360-degree shield termination, grounding and overall vehicle layout.
How Should I Choose Between 2m, 5m and 10m ?
Choose the most appropriate length that satisfies the installation route rather than automatically selecting the longest version.
In high-speed links, longer cables generally introduce greater insertion loss and may reduce system margin.
Cable length should therefore be determined according to actual equipment distance, PHY requirements, routing reserve and the complete link budget.
