Single Pair Ethernet – M12 Hybrid System


Hybrid transmission of SPE and power in just one cable and connector is intrinsically important for future IIoT applications. Devices are shrinking, the space for cables and interfaces is decreasing and at the same time the requirements for network connection and power supply are increasing. The hybrid SPE + Power interface M12 hybrid according to IEC 63171-7 is available in seven codings, each serving a specific power level, depending on the application. This makes the interface a useful extension of the functionalities of the M8 hybrid interface defined in IEC 63171-6.

Single Pair Ethernet – Cable standards and construction

Single Pair Ethernet is the technology that perfectly meets the industry's new network technology requirements in the context of Industry 4.0 and IIoT. Central elements of the standard are the Single Pair Ethernet cables. The International Electrotechnical Commission (IEC) has defined and standardized the structure and the high electrical properties in the IEC 61156 series of standards. This application note describes the cable standardization and its design in detail.
