单对以太网和 ix 工业技术

Helukabel 数据、网络和总线技术产品/销售经理 Horst Messerer 告诉 IEB，塑造工业网络和影响一代工业以太网发展的关键技术趋势是单对以太网技术。

“采用单对以太网技术的数据电缆与以前的解决方案不同，它们只有一对铜线。除了通过以太网进行数据传输外，这些电缆还能同时为终端设备提供高达 50 瓦的电源，Messerer 告诉《工业以太网手册》。

“到目前为止，这需要两对甚至四对电线，具体取决于传输速度和电源等级。对于用户而言，这种差异在几个方面是有利的。电缆更细更轻。这开辟了许多新的应用可能性——即使是在迄今为止使用传感器电缆或传统总线系统的地方。”

Messerer 说，另一个趋势是以太网接口 ix Industrial。这是一种插入式连接，比现有的 RJ45 标准要小得多，同时也更坚固。

“ix Industrial 根据 IEC 61076-3-124 进行了标准化，将数据传输和电源集成在一个接口中，从而显着减少了连接技术所需的安装空间。我预计这项技术将在众多应用中取代 RJ45 连接器，”他说。



 

这些新趋势提供了许多有助于先进工业网络解决方案的技术优势。

“与早期的两对和四对解决方案相比，单对以太网技术具有众多优势，”Messerer 补充道。“电缆直径减少了大约 25%，电缆重量也减少了 50%。此外，两个核心当然比四个或八个核心更容易和更快地连接——这减少了组装所需的工作量。”

他说，此外，更小的弯曲半径是可能的，这在铺设过程中创造了更大的灵活性。借助 PoDL（数据线供电），数据线还能够处理高达 50 瓦的电源。由于需要较少的原材料，单对以太网在更环保方面也具有优势。该技术使以太网的使用达到传感器级别，并使过程自动化的速度显着提高，从以前的 31.25 kBit（Profibus 和 Foundation Fieldbus）提高到 SPE 10BASE-T1L 标准的 10 Mbit。

关于ix Industrial技术，它以各种方式展示了它对工业以太网的好处。首先，插座和连接器通过两个卡扣实现双重锁定，确保了高抗冲击和抗振性。

多亏了 Cat.10，带有 10 个针脚的连接器专为高达 10 Gbit/s 的以太网而设计。6A 性能，并且由于它的电力传输选项也适用于混合电缆 - 以及总线、以太网和控制电缆。显着缩小的结构空间还允许将设备设计成更小的尺寸。

Horst Messerer, Product/Sales Manager – Data, Network and Bus Technology for Helukabel, told IEB that a key technical trend shaping industrial networking and influencing the development of the latest generation of Industrial Ethernet is Single Pair Ethernet technology.

“Data cables with Single Pair Ethernet technology differ from previous solutions in that they have only one pair of copper wires. In addition to data transmission via Ethernet, these cables simultaneously enable a power supply to end devices of up to 50 watts Messerer told the Industrial Ethernet Book recently.

“Up to now, this required two or even four pairs of wires, depending on the transmission speed and class of power supply. For users, this difference is advantageous in several ways. The cables are both thinner and lighter. This opens up numerous new application possibilities – even in places where sensor cables or traditional bus systems have been used up to now.”

Messerer said that another trend is the Ethernet interface ix Industrial. This is a plug-in connection that is significantly smaller and, at the same time, more robust than the existing RJ45 standard.

“The ix Industrial is standardised according to IEC 61076-3-124, combines data transmission and power supply in one interface and thus significantly reduces the required installation space for the connection technology. I expect that this technology will replace the RJ45 connector in numerous applications,” he said.

Technology benefits

These new trends are offering numerous technical benefits that are contributing to advanced industrial networking solutions.

“Single Pair Ethernet technology offers numerous advantages compared to the earlier two- and four-pair solutions,” Messerer added. “The cable diameter is reduced by around 25 percent and so is the cable weight by up to 50 percent. Moreover, two cores are of course much easier and faster to connect than four or eight cores – which reduces the effort required for the assembly.”

He said that, in addition, smaller bending radii are possible which creates more flexibility in the laying process. Thanks to PoDL (Power over Data Line), the data cables are also able to handle a power supply of up to 50 watts. As fewer raw materials are needed, Single Pair Ethernet also has an advantage in terms of being more environmentally friendly. The technology enables the use of Ethernet up to the sensor level and enables a significant speed boost in process automation from the previous 31.25 kBit (Profibus and Foundation Fieldbus) to 10 Mbit with the SPE 10BASE-T1L standard.

In regard to ix Industrial technology, it shows its benefits to industrial Ethernet in various ways. Firstly, there is the double locking of the socket and connector with the help of two snap-in hooks, which ensures high shock and vibration resistance.

The connector with ten pins is designed for up to 10 Gbit/s Ethernet thanks to Cat. 6A performance and is also suitable for hybrid cables because of its power transmission option – as well as for bus, Ethernet and control cables. The significantly smaller construction space also allows devices to be designed in smaller sizes.
