Connected devices with advanced sensors and control capabilities are becoming more mainstream in industry. The Industrial Internet of Things (IIoT) is on the rise thanks to powerful connectivity technologies and manufacturers' automation needs. This has led to an increased focus on edge computing and advanced sensor/control technologies. The increased density of devices creates interconnection challenges that can be mitigated by industrial wireless networks, but often require physical connectivity and are not available everywhere. Single-pair industrial Ethernet (SPE) has emerged to address the specific issues of industrial wireless networks.
What is Single Pair Ethernet (SPE) connector?
Single Pair Ethernet (Single Pair Ethernet) is an Ethernet technology that transmits data through a single pair of copper wires, which breaks through the limitations of traditional Ethernet in terms of space occupation and cost, and provides a new solution for data transmission in the fields of industrial automation and Internet of Things. Single Pair Ethernet connectors (Single Pair Ethernet connectors, referred to as SPE connectors) is this new Ethernet connection technology.
Second, where are the advantages of SPE connectors?
1, POE support: SPE connectors support POE (Power Over Ethernet), making fibre-optic interconnect technology can be directly accessed through the Ethernet, and through the traditional Ethernet equipment power supply.
2, low cost: compared to traditional Ethernet requires two or four pairs of wires, SPE only needs a pair of wires, which helps reduce cost and weight.
3, small space occupation: single pair of copper wire design significantly reduces the cable size and space occupation. the volume of SPE connector is about 20% of the volume of the RJ45 connector.
4, high frequency: SPE connector transmission frequency of 1-600MHz, while the traditional RJ45 is only 1-250MHz. the higher the frequency, the longer the transmission distance supported by the connector. Therefore, the longest transmission distance of SPE connector can reach 1000 metres, while the traditional RJ45 is usually not more than 100 metres.
5, high speed: SPE connector can achieve 1Gbps transmission rate within 40 metres. In the range of 1000 metres can provide 10Mbps transmission rate, to meet the new generation of high-speed data transmission needs.
6, high reliability: SPE connectors use a single pair of twisted-pair double shielded cable for communication, which can effectively reduce signal interference and transmission loss, improving the reliability of communication.
7, high adaptability: SPE connectors are waterproof, dustproof, shockproof, corrosion-resistant, etc., very suitable for a variety of different environments in industrial applications.
Third, what are the application scenarios of SPE connectors?
SPE connectors are widely used in industrial applications such as robotics, automation control, industrial internet of things, digital factory and so on. It can also be used in fields such as smart cities to achieve interoperability of city data. Specifically, SPE connectors have significant advantages in the following areas: Building and industrial automation: SPE connectors enable unified Ethernet communication from sensors to the cloud, providing efficient data transmission and power supply for building and industrial automation. Robotics: In the field of robotics, SPE connectors support fast and reliable data transfer and power supply between robots and control systems. SPE cables with only one pair of wires are much thinner and therefore more flexible than standard Ethernet cables. The thinner the cable, the more bending and twisting it can withstand. The result is a longer service life and cost savings.
Transport industry: In the railway industry, SPE connectors are used for data transmission and power supply in critical areas such as train control systems and signalling systems. SPE cables are approximately 1.6 kg lighter per 100 metres than standard Ethernet cables, and with this weight reduction, train operators can save around 14,000 euros in operating costs.
