Charting a course to the IIoT


Digitalisation is rapidly changing traditional industrial processes. HARTING is closely monitoring the current trends and developments shaping industrial transformation and producing robust, practical connector innovations and infrastructure solutions that provide easy access to the IIoT.

Ethernet is being deployed across more and more areas of automation and is the connecting element for both IT and OT (Operational Technology). To allow customers to implement correspondingly robust networks for industrial use, HARTING is constantly developing and refining its reliable Industrial Ethernet connectivity range.

With regard to Fast Ethernet and Gigabit Ethernet, the company has developed new variants of the robust RJ Industrial Multifeature interface. This solution assists with the fast assembly of network infrastructure, thanks to an integrated cutting tool that shortens assembly times by 25% and ensures a uniform finish. The Multifeature also comes with additional features such as a sturdy cable fastening and variable cable outlet direction.

Similarly, the preLink RJ45 is another time-saving tool. This unique system splits the cable and connector into two separate units; the first unit consists of connectors, sockets, couplings, or PCB terminals, whilst the preLink termination block is the second unit. It can accommodate up to eight stranded or solid wires, which can be simultaneously shortened and connected in one step. The cable, which can be assembled on-site, now fits in every preLink component and can be inserted, removed, or replaced at any time.

Fitting work for Ethernet applications in the field can often be awkward due to tight space conditions or time pressures. The M12 PushPull, with standing and recessed device sockets, offers a solution with handling, time, and reliability benefits and complies with the new IEC 61076-2-010 standard.

Traditionally, M12 connectors are attached via a screw connection, with a tool being used to achieve the necessary torque. The M12 PushPull uses a tool-free technique, whereby the two sections are simply clicked into place by hand. This method also means the assembly density can be significantly increased, helping to save valuable space.

Users of PROFINET-compatible cabling solutions should take a look at the miniaturised ix Industrial connector, which offers users a compact and industry-compatible interface for demanding applications in the PROFINET environment. It delivers Cat. 6A performance for 1/10Gbit/s Ethernet at the control level, whilst its high current-carrying capacity supports both existing and future Power over Ethernet (PoE) applications.

HARTING has slashed the PCB jack size by a substantial 70%, enabling manufacturers to use it in much smaller devices, which can then more easily meet the needs of miniaturisation. In addition, it combines both data transmission and power supply into a single interface, further reducing the area required for connectors within devices.

As well as significant space savings, the ix Industrial has been specifically designed and built to withstand the rigours of industrial environments. This resolves the issues associated with the RJ45, whose plastic locking tabs are easily broken in busy manufacturing environments, which can lead to contact problems as the connection works loose.

Finally, the development of new variants of the T1 Industrial interface for Single Pair Ethernet are also playing a special role, especially the interface standardised according to IEC 63171-6 in M12 and M8 housings. In addition, the new hybrid concepts for SPE plus Power according to IEC 63171-7 have been developed to meet power requirements beyond the possible 50W of Power over Data Line.

With the aim of making SPE technology accessible to further industrial application areas, HARTING has made the first solutions for single-pair connection via PCB terminal available. Terminals simplify the connection of SPE to an even greater extent, helping to bring Ethernet to the field level and simplify handling. This is particularly interesting within the context of SPE and IIoT with low data rates from 10 Mbit/s and transmission lengths of up to 1km in industry, building and process automation.
