在工业以太网网络上的大部分焦点都以拓扑和数据传输和存储等方面为中心。收到的关注远远不太关注。
所有类型的工业布线都没有工业连接器不足，包括例如M5到M23的连接器系列，用于数据和电力传输。但是，尽管市场上存在多个住房并在市场上形成要素因素选项，但是当谈到以太网时，标准的连接方法仍然是RJ45连接器 - 就像你在家或前台使用的那样。当然，对于工业应用，RJ45连接器更坚固苛刻，以防止环境因素。但RJ45连接器本身在很大程度上是相同的。
But that doesn't mean engineers aren't working to improve on the RJ45 for industrial Ethernet applications.
At TE Connectivity, for example, they have developed the Mini I/O connector system, which has a mating face envelope that is only 25 percent of the size of an RJ45 Jack.
TE Connectivity partnered with another connector supplier, Amphenol FCI, to develop the original Mini I/O plug as well as enhanced versions that feature EMI (electro-magnetic interference) shielding and CAT6A signal integrity performance to meet expected future industrial communication standards. In late 2017, the Mini I/O connector was adopted by the International Electrotechnical Commission (IEC) under the international standard IEC 61076-3-122.
在Mini I / O的IEC标准化下，连接器可以处理高达1 Gbps的数据传输速度。
京特·Feldmeier,全球标准化和缺点ortia leader of TE Connectivity’s industrial business unit, said that with acceptance of the technology under IEC 61076-3-122, the Mini-IO became “the first standardized, miniaturized industrial communication connector for an IP20 environment. Beyond its advantages for industrial applications in harsh environments, the small dimensions of the connector enable use of smaller devices and, therefore, higher packing densities inside cabinets.”
The Mini I/O connector differs from the RJ45—which was originally developed for use in telephone wiring—in that it was developed to be smaller and more reliable compared to the RJ45. According to a TE Connectivity white paper detailing Mini I/O connector technology, “The [Mini I/O] mating interface envelope reduction was realized by choosing fully enclosed metal shells, which…provide tight tolerances and mating interface stability.”
The white paper details testing of the Mini I/O against the RJ45 in comparable connection scenarios that exceeded the requirements of IEC 60603-7-3. In these tests, according to the paper, the Mini I/O performed best on several key performance criteria that are critical for industrial applications:
- Short discontinuities during vibration were lower due to a stable mechanical interface and double spring/double contact point layout.
- Resistance during cable movement was very stable during interface motions after environmental stress tests.
- EMI—screening attenuation of the Mini I/O was significantly better compared to all other RJ45 connectors tested.
