Single Pair Ethernet

The network infrastructure for the Industrial IoT

Hardware for the Ethernet of the future

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.

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

SPE for the process industry: Ethernet-APL

Ethernet-APL as a dedicated definition of SPE standard 10Base-T1L enables the direct connection via a two-wire solution considering special requirements of the process industry.

Ethernet-APL compliant connection from the PCB to the field
10 Mbit/s communication for long ranges according to IEEE 802.3cg-2019
PoDL (Power over data line) remote power supply according to IEEE 802.3bu

Data connections for the factory of the future

SPE connections transfer data and power over just one twisted pair. This enables both end-to-end IP communication between sensor and cloud, as well as power supply in complex IIoT solutions.

Advantages of two-wire cabling in conjunction with end-to-end Ethernet communication right into the field
Particularly robust, industry-compatible design
Most compact design for implementing IIoT devices – savings > 50%

Advantages of SPE connectors

Particularly compact

Miniaturisation of SPE connectors

Currently the smallest mating face according to IEC 63171 on the market
Only 20% of the volume of an RJ45 jack, therefore doubling the port-density
Can be integrated into standard M8 housings and connectors as with I/O-Link or PROFINET

Future-proof SPE connectors

Standardisation, 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.
