At the center of the interconnection system is the core module. It comprises the cable (TP, UTP, STP), the terminals (NanoMQS receptacle contacts), and the fixation element. Two NanoMQS contacts are crimped onto the two wires for termina- tion. After that the metal fixation element is crimped onto the insu- lation and the 2 position module holding the NanoMQS terminals. This module gets inserted into the frame. The frame gets inserted into the connector/header. The scalable approach (Fig. 5) makes it possible to combine any wire type (TP, UTP, STP) and shielding level within one layout. This approach was chosen to give the OEM a maximum of flexibility: Ideally Automotive Ethernet net- working shall be done with sim- ple and cost-efficient TP or UTP cable. This can be done neither with upscaling nor with downscaling efforts. This enables high flexibil- ity for TE's customers in regards to implementation strategies depending on the required EMC levels needed. From a cabling perspective and using MATEnet interconnection technology, all the OEM needs to do now is to replace the cable and the frame to use the higher shielding within the installed system. The header/ connector on the ECU remains the same. On the other hand an OEM may start with STP cable but testing might reveal that UTP would meet the application requirements just as well. In that case the cable can simply be downgraded without any layout changes at the ECU interface because again, the only change required is using a different MATEnet frame and cable. The core module with the terminals and crimps always remains the same. MATEnet connectors support different wire gauges (from 0.13 mm 2 to 0.35 mm 2 ), but 0.13 mm 2 is currently considered to be the most relevant.
