Aloha Ethernet!

The Evolution of Industrial Networks

When Professor Abramson from the University of Honolulu wanted to streamline communication between university locations with a data network in 1970, he had no idea how his ALOHAnet would go on to change the world. The world’s first data network provided the impetus for the development of the most widely used Ethernet communication standard for industrial plants and facilities today. Over several product generations, the HARTING Technology Group has played a key role in shaping and designing this evolution. Such future-proof solutions are particularly needed Especially for the infrastructure of IIoT such future-proof solutions will be essential. Let’s embark on a short journey through time...

Industrial networks: Robust and fail-safe

HARTING recognised the special requirements for cables and connectors for industrial networks at an early stage. These components had to be particularly robust and above all fail-safe. The RJ45 interface for Ethernet designed for the office sector was not suitable for industrial scenarios. There interfaces were not capable of standing up to shocks, vibration, electromagnetic influences and aggressive gases or liquids.

RJ Industrial® reliable in harsh environments

With the advent of RJ Industrial® connector, HARTING launched an optimized version of the RJ45 interface that meets industrial requirements. Easy field assembly combined with a shatterproof locking clip and effective shielding make it a bestseller in automation to this day. Whether in IP20 or protected IP65/67 PushPull version, with the RJ Industrial® users can rely on always having the right interface for reliable Ethernet networks.

All for Ethernet
Under the claim "All for Ethernet" HARTING sets new standards for industrial networks.

Award winning miniature

Devices and components are becoming increasingly compact and so are their interfaces as a result. HARTING meets the demand for miniaturized Ethernet interfaces with the ix Industrial®. The socket requires an impressive 70% less space in the device than RJ 45 sockets and is more powerful, shielded and robust at the same time. In addition, it features a metal locking mechanism and is standardized in accordance with IEC 61076-3-124. This rightly positions the ix Industrial® connector as one of the "famous" Little Giants heroes. Consequently, it comes as no great surprise that the connector has already won three awards:

  • 2017 the "Innovator of the year for ix Industrial®"
  • 2018 Winner "Best of Industry Awards" and "Winner in the Automation category
  • 2019 "Innovative Product Award", China


Straight from the cloud to the most compact sensor

According to the industrial Internet of Things (IIoT), the concept of Industry 4.0, "smart devices" communicate with each other. They constantly exchange data with each other for production processes and also enable the flow of data from the cloud down to the field level, right down to the most minute sensor. All this is enabled by by Single Pair Ethernet, the SPE technology, in which the transmission of Ethernet only runs over a single pair of copper wires. In this way, sensor/actuator networks are directly connected to the cloud with real-time capability. In addition, SPE in machines, robots or in railway technology contributes to weight and space savings. The entire cabling becomes simpler and can also be installed much faster. The T1 Industrial is HARTING's answer to this new transmission technology – a genuine game changer for the IIoT.

Ready for the future:

  • HARTING Technology for Ethernet supports IIoT.


For future decision-makers in industry:

  • More compact interfaces for successful miniaturization of industrial applications.
  • Award-winning technology.
