Available Configurations

4 Port Z Coded Male to 4 Port Z Coded Male
Both ends are the H-MTD 4 port Z coded male, water blue housing with pink latch.Use it as a 4 port to 4 port extension when a factory H-MTD 4 port female pigtail is too short, or when bridging two 4 port Z coded female panel receptacles.
The male to male gender keeps both factory pigtails unchanged, and the GG2SPEED 251 shielded cable keeps all four multi gigabit channels clean. The 0.5 m to 5 m range covers tight ECU jumps to full trunk runs.
4 Port Z Coded Male to 4 Port Z Coded Female
One end is the 4 port Z coded male, E6S10D-1CAZ5-Z, and the other end is the 4 port Z coded female, E6K10D-1CAZ5-Z, both water blue.
Use it when you need to adapt a 4 port male pigtail to a 4 port female socket, such as bridging two factory harnesses that have opposite genders. The male end plugs into a female receptacle and the female end accepts a male plug. The 0.5 m to 5 m range covers dashboard and trunk routing.


4 Port Z Coded to 4x Single Port Z Coded
The 4 port Z coded male end plugs into a factory 4 port Z coded female pigtail, and the cable fans out to four H-MTD single port Z coded female receptacles, part number E6K10A-1CAZ5-Z, water blue.
Use it when the four multi gigabit channels need to reach four separate single port female devices, such as four cameras or four radar sensors. Each single port female accepts a standard H-MTD male pigtail. The 0.5 m to 5 m length range covers dashboard to sensor and trunk routing.
4 Port Z Coded to 4x Single Port Z Coded
The 4 port Z coded male end plugs into a factory 4 port Z coded female pigtail, and the cable fans out to four H-MTD single port Z coded male plugs, part number E6S10A-1CAZ5-Z, water blue.
Use it when the four devices on the other end have single port female sockets, such as four female ended cameras or test jigs. Each single port male plugs directly into a female socket without an adapter. The 0.5 m to 5 m lengths cover sensor to ECU and bench test routing.


4 Port Z Coded Male to 4x Bare Cut Wires
The 4 port Z coded male end plugs into a factory 4 port Z coded female pigtail, and the other end is left as four bare cut wires with the pairs exposed.Use it when you need to terminate the other end yourself, such as soldering to a test board, mating to a non H-MTD connector, or building a custom harness.
The 4 port male end gives you a certified H-MTD interface, and the bare ends let you define your own termination. The 0.5 m to 5 m range covers bench to device routing.
4 Port Z Coded Female to 4 Port Z Coded Female
Both ends are the H-MTD 4 port Z coded female, part number E6K10D-1CAZ5-Z, water blue housing.Use it as a female to female extension when a factory H-MTD 4 port male pigtail is too short, or when bridging two 4 port Z coded male panel receptacles.
The female to female gender keeps both factory pigtails unchanged, and the GG2SPEED 251 shielded cable keeps all four multi gigabit channels clean. The 0.5 m to 5 m range covers tight ECU jumps to full trunk runs.

Applications
| Application | How It Is Used | What It Enables |
| Gender change | Adapt a 4 port male pigtail to a 4 port female socket. | Bridges two factory harnesses with opposite genders. |
| Bench test rig | Wire H-MTD 4 port ECUs to four single port test instruments. | Repeatable 10G test links instead of four hand built cables. |
| 4 port extension | Extend a factory H-MTD 4 port pigtail with male to male or female to female. | Reaches a relocated ECU without cutting the factory harness. |
| Custom harness build | Use the bare wire end to terminate to your own connector. | A certified H-MTD interface with custom termination on the other end. |
| Zonal controller fan out | Break the 4 port Z coded male out to four single port sensors. | Four multi gigabit channels reach four cameras or radar units from one ECU port. |
Closing line: because all four channels run through factory terminated H-MTD connectors on the same shielded GG2SPEED 251 cable, the multi gigabit links stay impedance matched end to end.

Product FAQ
Q1: What data rate does it support?
Up to 10 Gbps over the GG2SPEED R 251 fully shielded twisted pair, built for multi gigabit automotive Ethernet, and backwards compatible with gigabit and 100 Mbps links.
Q2: Is this a genuine Rosenberger H-MTD connector?
Yes. The 4 port Z coded male housing is genuine Rosenberger HDCS H-MTD, part number E6S10D-1CAZ5-Z, water blue with pink release latch. The cable is original GG2SPEED R 251 fully shielded 10G automotive Ethernet.
Q3: What is the difference between the 4 port and single port H-MTD?
The 4 port housing carries four independent channels in one connector. The single port housing carries one channel. Configs 3 and 4 break the 4 port out to four single port connectors when the devices on the other end each have their own single port socket.
Q4: What is the difference between the six configurations?
Config 1 is 4 port male to 4 port male for extension. Config 2 is 4 port male to 4 port female for gender change. Config 3 fans out to four single port females. Config 4 fans out to four single port males. Config 5 terminates to four bare cut wires. Config 6 is 4 port female to 4 port female for extension.
