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.



Smallest compact design for implementing IIoT devices



Easy to connect for safe, fast installation



Future-proof design through international standards

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

White paper

In this white paper you will get detailed insights into the possibilities of the young Single Pair Ethernet technology, with a focus on applications, the state of standardization and the development of connectors.


In short clips our SPE expert explains why SPE is the network infrastructure of the Industrial IoT. Let us introduce you to the communication architecture of tomorrow.

Standardisation, the key to success

Standardisation, the key to success

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.
