Single Pair Ethernet

The network infrastructure for the Industrial IOT

Hardware for the Ethernet of the future

The increasing level of digitalization 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.

Weidmüller and partners from the field of electrical connectivity all rely on the innovative Single Pair Ethernet technology when developing new industry standards.

Turning four into one: The advantages of SPE explained in simple terms

Instead of two or four pairs of wires, Single Pair Ethernet cabling requires just one pair of wires for the transmission of data and power. The simple design and the associated reduction in weight, space requirements and installation costs offer many advantages in an industrial environment. Single Pair Ethernet enables the end-to-end, economical connection of a large number of terminal devices in the Industrial IOT, from sensors in the field to the cloud.

Advantages of SPE connectors

Particularly compact

Miniaturization of SPE connectors according to IEC 63171-2

Weidmüller has been developing user-friendly connectors for industrial use, according to IEC63171-2. With a pitch of 7.62mm the compact connector system saves up to 50% space in comparison to RJ45 interfaces. The vertical arrangement of the two contacts allows a very high packing density. This enables device manufacturers to save valuable space on the PCB and to build smaller devices. This reduces port costs in device construction and effectively saves space in the control cabinet.

Currently the smallest mating face according to IEC 63171 on the market
Doubling the Port-Density compared to RJ45 in the same housing contour
Only 20% of the volume of an RJ45 jack
Can be integrated into standard M8 housings and connectors as with I/O-Link or PROFINET
M8 connectors with male and female contacts available
Front and rear panel mounting with male and female contacts supported

Made for highest demands

The industrial suitability of SPE connectors

Originally developed for automotive applications, the aim of single pair ethernet technology was to realize the most efficient infrastructure capable of delivering high performance with as little cabling as possible. There are similar expectations within industry applications and building automation where the number of intelligent end devices in the plant is increasing but the amount of available space is not. Weidmuller SPE connector solutions deliver long cable lengths, a compact design that is simple, robust and vibration-proof, as well as being insensitive to electromagnetic influences.

Robust metal housing with metal snap-in hooks
Shock resistant and vibration resistant according to IEC 60068
Coupling attenuation at 600 MHz according to IEEE 802.3
Optimum shield connection on the PCB due to four symmetrical legs
PCB connectors for environments up to pollution degree 2

Easy to use

The simplicity of SPE connectors

Ethernet technology is too complex for many industrial applications. SPE components are clearly superior due to their simplicity. Compared to four-pair Ethernet, installation is less difficult and allows a significant reduction in space and weight. SPE connectors also enable robust cabling in a short time. At the same time, they offer extended cable lengths in an extremely compact design.

Industry standard plugs and sockets with metal Snap-in hooks locking
Simple assembly due to a two-part connector
Suitable for all commercially available SPE cables
Trouble-fee integration into M8 housings and connectors
Compatibility of IP20 and IP67 variants

Ready for the challenges of tomorrow

Future-proof SPE connectors

SPE is the next milestone in network technology, as it enables continuous intelligent networking across all levels. SPE is scalable, deterministic, and fully compatible, allowing all components to communicate with each other. As a comprehensive key technology for applications in the field of Industry 4.0 and IIoT, it will form the core of a wide range of industrial applications in the future.

Extensive support within the Single Pair Ethernet System Alliance
Suitable for various Ethernet applications with transfer rates from 10 Mbit/s to 1 Gbit/s
Bandwidth of up to 2.5 GHz
SPE technology can be used in standard M12 connectors

Standardization, the key to success

When developing new standards, the most important task is to establish a uniform and application-independent plug-in-connector face. Together with other manufacturers Weidmüller supports the currently submitted standardization variants according to IEC 63171-2 for IP20 and IEC 63171-5 for IP67.
