Harting is driving the development of the standardisation of the new Single Pair Ethernet (SPE) technology forward. Now, in a multi-stage selection process, international standardisation committees have decided in favour of the Technology Group’s SPE mating face.

Single Pair Ethernet (SPE) is a new Ethernet technology that requires only one pair of wires (instead of four pairs) to transfer data and power. This technology, which is driven by the automotive industry, is also gaining increasing importance in automation technology, where its development is advancing in a targeted manner. Thanks to its simplicity and an associated reduction in weight, space requirements and installation effort, a great future is seen for the technology within the industrial sector, automation technology and the rail industry, among others.

SPE now makes it also possible to implement digitisation down to the field level, i.e. end-to-end IP-based communication. Equipping simple sensors or cameras, reader and identification devices, etc. with Ethernet interfaces supports the implementation of Integrated Industry and IIoT.

End-to-end compatibility of devices, cables and connectors

The end-to-end compatibility of devices, cables and connectors is a prerequisite for the widespread use and consequently the successful marketing of SPE technology. This is ensured by international standardisation (ISO/IEC and IEEE). Since the beginning of the year, there has been an internationally drafted selection process for the cabling and selection of standard SPE mating faces via ISO/IEC involving more than 20 national expert committees. As a result of this selection, two mating faces have prevailed

Based on this mating face, the company is preparing a comprehensive product portfolio for the industrial sector. The technology had been driven forward in the past two years in close cooperation with customers.
