IEC 63171-7 standard for hybrid interfaces
CIE Magazine talks to Eric Leijtens, global product management and managing director, TE Connectivity about the IEC 63171-7 standard
CIE Magazine: Which core aspects does the IEC 63171-7 standard cover?
Eric Leijtens: The IEC 63171-7 standard is an important step forward in realizing Industry 4.0 ideals and advanced manufacturing concepts. It is intended to create broad consensus on an open standard, specifying an M12 connector interface, one of the most common sizes used in field-level automation applications. This widely used format will enable power transmission up to 11kW/8A and high-speed data transmission up to 1Gbps/600MHz in one cable.
What are the benefits of the IEC 63171-7 in industrial applications?
Today’s industrial networks are complex ecosystems that frequently require
connections that impair transparent communication and are more costly

than necessary. Single pair ethernet (SPE) technology enables the network to be IP-based and fully transparent from the sensor to the cloud, a significant challenge previously. Among many other advantages, adopting the “-7” standard allows engineers to easily integrate SPE with their existing ethernet infrastructure, eliminating the need for special and expensive connections to exchange data with individual sensors on the network. With broad industry
consensus, customers can be confident they are implementing a technology that will be supported well into the future.
For which applications is the IEC 63171-7 most suitable? Nearly any data-driven industrial application is a good candidate for SPE technology, particularly those applications where field-level connectivity is challenging. The “-7” hybrid interface, however, increases both data rates and power ranges/supply compared to previous options. This makes it an excellent solution for a wide range of high-power applications like DC servo drives, small three-phase drives, and many others.
To what extent do the SPE Industrial Partner Network and the SPE System Alliance support the IEC 63171-7 standard?
We are pleased to announce that both trade groups - in total, more than 80 companies - fully support the new “-7” standard. This specification sets a universal, open
standard that enables the entire industry to easily integrate SPE technology into their field devices. The common M12 format will provide the ability to work with multiple suppliers, ensure competitive pricing, and decrease the risk of production downtime.
Which roadmap does TE follow concerning the IEC 63171-7 standard?
The “-7” standard makes it simple to bring SPE technology to the network edge, transparently connecting the entire network from the cloud all the way down to field- level devices. In industrial applications, these devices are operating in harsh environments and customers need highly durable connections to realize the benefits of SPE. This means forming connections that are ingress-protected from dust, particulate matter, and water immersion. TE Connectivity will soon be releasing IP67- rated SPE connectors that are compliant with the IEC 63171-7 standard.
