The potential of Single Pair Ethernet is huge and experts consider it to be the next generation of communication architecture in automation. Originally developed for automotive applications, it promises nothing less than a continuous connection from the sensor to the cloud. And this is the case in practically every application, whether in industry, logistics, buildings or wherever data is generated. The concept behind it is essentially an extension of the Ethernet to the sensor, that is wherever "tracks" (in the literal sense) rather than data highways are needed in every inch of space within the plant – it is compact, flexible and offers extensive reach.

The increasing level of digitalisation of industrial plants calls for the further development of existing Ethernet cabling. For sensors and local, modular control units in particular, conventional cabling concepts are no longer able to meet the new demands with regard to space requirements and installation effort.

Single Pair Ethernet (SPE) is an Ethernet standard for data transmission over a single pair of wires (2-wire Ethernet). SPE is developed to simplify and improve data transmission in industrial applications by providing a simple and cost-effective way to build Ethernet networks over existing wires.

In the development of new industry standards, Weidmüller, together with partners (companies from the connection technology sector), relies on the innovative Single Pair Ethernet technology. Single Pair Ethernet enables the end-to-end connection of a large number of devices in the Industrial IoT, from the sensor to the cloud.
