Harting Single Pair Ethernet is the key technology for the factory of the future


The Industrial Internet of Things (IIoT) is growing at a rapid pace. Experts agree that Single Pair Ethernet (SPE) will be one of the key technologies that significantly shapes the success of the IIoT. The factory of the future requires high data streams and the industrial sector needs connectivity which adapts itself to increasingly growing demands. This is most effectively achieved via standards that are developed and advanced through partnerships in an open eco-system.

HARTING has recognised the requirements of the factory of the future, driven the development of Ethernet connectivity for tomorrow’s networks and presented intelligent connectivity with solution packages for the Cloud, Edge and IIoT.

As an enabler of IIoT, HARTING is taking the step from a technology trend to a real application and customer solution. With an interface standardised according to IEC 63171-6, the technology group is consistently recognising trends, defining standards and delivering high-quality products.

Generations of network engineers, planners, installers and users have learned that Fast Ethernet (10/100Mbps) requires cabling with two wire pairs and Gigabit Ethernet requires four wire pairs. The new Single Pair Ethernet is pushing technology into the market that can transmit these TCP/IP-based data streams via just one pair of wires.

This technique, which is being driven by the automotive industry, is increasingly gaining importance in automation technology, where it is being further developed in a targeted manner. Due to its simplicity and the associated reduction in weight, space requirements and installation effort, this technology has a great future within industry, automation technology and the rail industry, among others.

SPE now makes it possible to bring digitisation, i.e. continuous IP-based communication, to the field level. Equipping simple sensors, cameras and reading and identification devices with Ethernet interfaces supports the implementation of Integrated Industry and IIoT. IP-based communication from the Cloud down to every sensor has long been a sought-after vision that now takes on a very real form.

Consistent compatibility of devices, cables and connectors

A prerequisite for the widespread use and successful marketing of SPE technology is the end-to-end compatibility of devices, cables and connectors. Since the beginning of the year, an ISO/IEC international selection process has been in progress for cabling and the selection of standardised SPE mating faces, involving more than 20 national expert committees. Because of this selection, two mating faces have prevailed:

  • for building wiring, the mating face according to IEC 63171-1, based on the proposal by CommScope
  • for industrial and industry applications, the mating face IEC 63171-6, based on the proposal by HARTING.

The core element of the new HARTING T1 industrial connector family is an always-uniform SPE mating face that is used for all versions, from IP20 up to IP65/67. HARTING has aligned its connector design accordingly and can achieve both 1GBit/s for shorter distances and 10Mbit/s for long distances with a mutually compatible mating face. f the new HART

HARTING develops solutions for Single Pair Ethernet with TE Connectivity


HARTING is cooperating with TE Connectivity (TE), a world leader in connectivity and sensors, to set Single Pair Ethernet (SPE) as the de-facto infrastructure solution to enable the Industrial Internet of Things (IIoT). The two companies will together drive solutions which will define the infrastructure for SPE.
There are several SPE standards in IEEE 802.3 covering wired Ethernet technology for LANs and WANs. The latest, 802.3cg 10Base-T1, for distances up to 1 km, will be released in 2019. SPE allows for a single open, scalable Ethernet-based network within the automation system. This significantly reduces complexity, costs and enables the technology to go beyond existing borders.

HARTING and TE Connectivity are inviting companies to partner up to drive Single Pair Ethernet as the infrastructure solution for the fast-growing IIoT market. “Single Pair Ethernet is the technology on which we will build the road to the future success of the IIoT,” said Eric Leijtens,Global Product Manager Industrial Communication, TE Connectivity. “With the new interconnection standard IEC 63171-6, we have an outstanding opportunity to reap the full potential of the Industrial Internet of Things,” added Frank Welzel, Director Global Product Management, HARTING Electronics.

Harting announces Rear mounting option available for Han® metal hoods and housings


The metal hoods and housings of the Han® B, EMC and M series now offer rear mounting options for contact inserts, a solution which greatly simplifies the preassembly of interfaces for control cabinets.

With the new Han® metal housings, it is possible to lock the prefabricated inserts directly from the rear into the bulkhead mounting housing from the interior of a control cabinet. In the past, Han® inserts had to be conducted from the inside of the cabinet through the panel cutout, before they could be preassembled outside. After that, they were pushed back and fixed into the bulkhead mounted housing.

By the end of this year, rear mounting inserts with a continuous 360°-degree shielding will also be available. With Han® EMC, the shielding is always on the metal hood or housing, with the hoods requiring special EMC cable glands.

With the new mounting options, the preassembly of cabinet components becomes simplified and increasingly efficient, as more elements of control cabinets, machine modules and cable harnesses can now be prefabricated separately. As a result, the proportion of prefabrication increases and the overall assembly costs decrease. Further cost savings are achieved as the new and old variants of the Han® metal hoods and housings are completely compatible with each other.

Mini Displayport added to Cliff’s FeedThrough Connecter Range


Cliff Electronics announces the addition of a Mini Displayport to its market leading range of FeedThrough connectors. Assembled into an industry standard XLR connector panel cut out the Mini DisplayPort (MiniDP or mDP) is a miniaturised version of the widely used DisplayPort audio-visual digital interface

Frequently fitted to PC and notebook motherboards and AV Systems, unlike its Mini-DVI and Micro-DVI predecessors, the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 (WQXGA) in its DisplayPort 1.1a implementation, and 4096×2160 (4K) in its DisplayPort 1.2 implementation. With an adapter, the Mini DisplayPort can drive display devices with VGA, DVI, or HDMI interfaces.

Cliff’s XLR format FeedThrough connectors take advantage of the standard 24mm panel cut out widely used in audio and broadcast systems and which is finding increasing popularity instrumentation, medical and industrial applications due to the format’s flexibility, security and reliability.

A true FeedThrough connector, the new Cliff Mini Displayport is connected on both sides of the control panel using standard cables, greatly simplifying system assembly. It is available with a plastic or metal faceplate, may be front or rear mounted to a panel and offers plain, countersunk or M3 threaded mounting holes.

John Hall, Managing Director of Cliff Electronics, comments; “We have a large market supplying pro-audio, broadcast and audio-visual OEMs and systems integrators. Our new Mini Displayport adds to our very successful range of FeedThrough connectors and comes a step closer to making us a one stop shop for system designers. All of our FeedThrough connectors are mounted in the widely used XLR footprint simplifying panel design and manufacture and improving system aesthetics. We can also supply our new Mini Displayport connectors pre-assembled into rack panels offering systems integrators fast and convenient system assembly.” 

Cliff’s Feedthrough connectors now provide  Analogue, Digital and Optical Feed-Through connectivity in formats including Firewire, GJ45, HDMI A-A and 50 ohm BNC versions, USB2 A-to-B and B-to-A “gender change” sockets high speed USB Type – C, USB3 to USB3 in all gender changing configurations – A-A, A-B and B-A. Also available are all popular data and Ethernet connectors including USB 2.0 and 3.0, LC and SC fibre (Duplex & Simplex), UTP and FTP RJ45s in both Cat6 and Cat5e (shielded and unshielded), Toslink, RCA Phono and HDMI and blanking plates.
