H-MTD® – High-Speed Modular Twisted-Pair Data


Rosenberger H-MTD®, H-MTD®+ and H-MTD®e are differential connector systems up to 20 GHz for high-speed data transmission of up to 56 Gbps, contained in a compact yet robust automotive grade housing. Apart from ensuring high-bitrate data transmission, savings on installation space and weight, a further major advantage of this connector system is its modularity, providing the flexibility to support a wide range of Ethernet applications and industry protocols.

The application field of the Rosenberger H-MTD® is countless as it can be used with a variety of different cables including Shielded Twisted Pair, Unshielded Twisted Pair and new High-Performance cables. With H-MTD® the customer can count on an interface that accommodates future vehicle networks, applications and protocols.

Rosenberger H-MTD® is compliant to all common automotive standards.

Connector Position Assurance – CPA prevents Unintentional Disengagement
High-speed data connectors are increasingly required in safety applications such as autonomous driving and driver assistance systems. In response, Rosenberger has developed an optional CPA (Connector Position Assurance) solution which improves connection reliability.
The CPA cannot be activated if the connector has not been completely mated. When aligned correctly the CPA can be closed.
