In summary, single pair Ethernet can provide benefits in many different industries and can be used in several different application fields. Single pair Ethernet has the potential to close the Ethernet gap on the field level. It is a milestone in driving Ethernet multi-level interoperability in different market segments such as factory automation, building automation, and process automation. It also extends the length and the bandwidth compared to many existing fieldbus and I/O systems, and therefore can substitute the necessary gateways to run the link of various different existing fieldbus systems. It can reduce the “zoo” of different fieldbus protocols that still exist in the industry. Providing data and power over one SPE has the potential to significantly reduce the cost, weight, and installation efforts. Single pair Ethernet is the disruptive communication technology of the future, and Weidmüller provides a complete product range of connection technologies that are compact, robust, future-proof, and easy to use.
