The chances are you may have heard of single pair ethernet, or SPE for short, however rest assured the new industrial data transmission system is already on its way to becoming a megatrend in the industry.
Ethernet was originally developed back in the 1970's to connect wired computer terminals together locally, which became the birth of local area networks better known as LAN. In the 1980's fieldbus technology was taking hold in industry enabling communication between sensors and controls however couldn't communicate with Ethernet systems. In more recent years industrial communication protocols such as Profinet, Ethercat etc. utilise Ethernet as a core component in data transfer. The needs in industry are far more robust with higher IP6# requirements compared to the IP20 needs at the computer control levels.
The industrial internet of things, IIoT, and Industry 4.0 are driving new standards for data communication and connectivity in industrial automation and smart factories. The requirements do not require much power or high data rates however do need fast, reliable and secure data transmissions. SPE technology meets these new demands achieving seamless communication connections from the computer control level to the industrial factory floor. SPE uses lower transmission rates of up to 100Mbps however can achieve far greater data transfer distances of up to 1000 meters. The connection interfaces are far more compact than standard two and four wired devices which are predominantly using RJ45 connectors today. SPE will therefore support the trend towards more compact decentralised devices used in industrial and building automation applications.
Phoenix Contact are a major driving force behind the standardisation of the new interfaces utilised in SPE and are working alongside market leading partners to develop SPE technology.
For a really good introduction and explanation of this new mega trend in industry watch the SPE video included in this blog and watch this space for future updates.
