IIoT - Single Pair Ethernet (SPE)

SPE - One Wire Pair - An Infinite Number of Applications

Single Pair Ethernet (SPE) reduces data transmission to a single twisted pair of wires and enables data rates of up to 1 Gbit/s at distances of up to 1000 meters. It supports multidrop networks, power supply and hybrid installations via the same cable and reduces cabling costs. Depending on the application, existing infrastructure can continue to be used.

SPE offers uniform, Ethernet-based communication from the sensor to the cloud and is a key technology for Industry 4.0 and the IIoT. Advantages such as space, weight and cost savings make it ideal for industrial and commercial applications.

Future-proof solutions are based on the upcoming IEC 63171-7 ED2 standard, preparing networks for Industry 4.0 and IIoT requirements.

The new IEC 63171-7 ED2 standard: Paving the Way for SPE Success

The new IEC 63171-7 ED2 standard, initiated by the PROFIBUS User Organization (PNO), forms an important basis for the further development and success of Single Pair Ethernet (SPE). Together with other PNO, Rosenberger is actively driving forward the development of a future-proof Single Pair Ethernet (SPE) connector. The IEC 63171-7 ED2 standard defines a universal mating face for applications in control cabinets and in the field. It ensures future-proof, multi-vendor interoperability, laying the foundation for widespread adoption of this technology.

Only through uniform, globally accepted standards can SPE reach its full potential and ensure long-term success in industrial and commercial applications.

Trends shaped by Rosenberger from Automotive to Industry

Rosenberger - established as a leading manufacturer of connectivity systems for Single Pair Ethernet (SPE) products in the automotive industry - offers a wide range of products specifically designed to meet the requirements of SPE in the vehicle, such as MTD^® and H-MTD^®. Space-saving (miniaturized), lightweight and robust differential connector systems that meet today's mechanical and environmental requirements.

Originally developed for automotive applications, SPE now offers the perfect balance of speed, distance and power for a wide range of IoT projects. Based on familiar Ethernet and TCP/IP protocols, SPE extends the reach of Ethernet everywhere - even to sensors located in the most remote corners of the system or in the field. Power over Data Line (PoDL) ensures that sufficient power is available to power a wide range of IoT components and sensors.

Industry often requires special solutions. These include longer cable runs, higher electromagnetic compatibility (EMC) and specific industrial protocols. To meet these requirements, Rosenberger is actively involved in the development and implementation of SPE standards and products.

Many years of experience with SPE technologies and products in the automotive industry are transferred to industrial applications. This makes Rosenberger the ideal partner for Single Pair Ethernet.

What are SPE connectors?

Single Pair Ethernet (SPE) connectors are designed to meet the needs of modern industrial networks. They enable compact and reliable connections that combine data transmission and power over a single cable. As data rates increase and smarter devices become smaller, lighter and faster, SPE connectors offer the ideal solution. Their low weight, small bend radius and compact design support space-saving and efficient applications. They meet the growing demand for high data rates and are ideal for ensuring the performance of today's networks.

SPE connectors are based on international standards (IEC 63171), enabling easy integration of sensors, actuators and other devices into Industrial Ethernet networks.

These standards promote compatibility and ensure reliable use in various applications.

SPE - simply explained

The SPE system simplifies data transmission by using only a single wire pair for communication. Classic Ethernet, long established in the upper levels of automation, often reaches its limits at the field level: It is too complicated to install, has too short a range, and is not designed for rugged use at the plant floor. This is where Single Pair Ethernet (SPE) comes in, improving Ethernet where it has been weak.

Advantages:

Standardized communication: Enables consistent Ethernet-based communication from sensor to cloud
Key technology: Paves the way for Industry 4.0 and IIoT
Efficient infrastructure: Low cabling costs by leveraging existing infrastructure
Long range: transmission distances of up to 1,000 m and more
High performance: Transmission speeds of 1 Gbps and more
Resource-efficient: Minimizes weight, space and installation requirements

SPE dramatically simplifies infrastructure and paves the way for future-proof industrial automation applications
