Single Pair Ethernet (SPE) is an Ethernet technology that transmits both data and power over a single twisted pair. This enables seamless, IP-based communication from the sensor to the cloud - while reducing space requirements, weight, and cabling complexity.
Especially in industrial applications, Single Pair Ethernet provides an efficient solution for integrating sensors, actuators, and IoT devices into modern Ethernet networks.
SPE was specifically developed for industrial applications where space, weight, and reach are critical factors. Conventional Ethernet often reaches its limits at the field level - due to complex cabling, limited range, or insufficient robustness.
SPE enables the direct integration of sensors, actuators, and other devices into a seamless Ethernet network - without the need for additional gateways. This results in a streamlined, scalable, and future-proof communication infrastructure.
Rosenberger has many years of experience in developing Single Pair Ethernet solutions for the automotive industry. Connector systems such as MTD® and H-MTD® were specifically designed for demanding vehicle environments and meet the highest requirements in terms of robustness, compactness, and reliability.
Rosenberger leverages this expertise for industrial applications. As a result, customers benefit from proven technology across the entire value chain - from development to the implementation of high-performance SPE networks.
The new IEC 63171-7 ED2 standard β initiated by the PROFIBUS User Organization (PNO) β forms the basis for the success of Single Pair Ethernet (SPE).
The standard defines a universal mating face for Single Pair Ethernet in industrial applications.
It ensures:
Together with other PNO members, Rosenberger is actively driving the development of this standard forward.
Single Pair Ethernet (SPE) connectors reliably transmit both data and power (PoDL) over a single twisted pair.
This makes them ideal for industrial applications with high device density and limited installation space.
Thanks to international standards (IEC 63171), sensors, actuators, and other devices can be seamlessly integrated into Ethernet networks.
Power over Data Line (PoDL) extends Single Pair Ethernet (SPE) by adding reliable power delivery - enabling a streamlined, efficient, and future-ready infrastructure. This allows end devices to operate without a separate power supply.
PoDL enables modern, high-performance, and cost-efficient networks - perfect for robotics, industrial automation, building systems, and IIoT applications.
Seamless communication from the sensor to the cloud is essential in the factory automation. Comprehensive data networking and analysis are necessary to predict maintenance cases, plan raw material requirements, and efficiently implement individual customer requests. The challenge lies in ensuring that data is transmitted reliably and quickly. It is also vital that it functions quickly and reliably over longer transmission distances, and that it is easy and flexible to integrate into both IT and OT.
Ethernet down to field level with SPE and PoDL
Single Pair Ethernet (SPE) opens up new possibilities for industrial production and communication. It provides reliable Ethernet connectivity via a single twisted pair of cables, reaching directly up to the sensor and actuator level. This reduces space requirements, simplifies installation, and enables the creation of consistent IP-based networks. SPE is used in areas such as intelligent device communication, sensor technology, and monitoring, for example for barcode readers, camera systems, and user interfaces.
Another advantage is that Power over Data Line (PoDL) enables power and data to be transmitted via a single cable. This eliminates the need for separate power cabling, saving time, costs and space.
Future-proof infrastructure for Industry 4.0
SPE and PoDL enable standardised, Ethernet-based communication from sensors to the cloud. As key technologies, they pave the way for a new generation of industrial automation that is powerful, compact and networked. Automation
Precise and fast data transmission is essential in modern robotics. This enables complex movements, real-time control and interaction with the environment.
In addition, space and weight savings are decisive factors for mobile or collaborative robots. Rigid cabling restricts the flexibility of robot arms, accelerates wear and tear, and limits their use in confined or dynamic environments. Lighter, slimmer cabling can significantly increase the agility and service life of systems. As sensors and actuators transmit and require power, a compact, flexible power supply is essential.
One cable. Two functions
Single Pair Ethernet (SPE) optimises miniaturisation of communication infrastructure in robotics. Compared to classic fieldbus systems, SPE provides:
Increased manoeuvrability for robotics
Combining SPE and PoDL allows for the development of powerful robotic systems with leaner, more flexible and durable cabling. This improves manoeuvrability, reduces maintenance costs, and makes integration into flexible production environments easier β a decisive step towards flexible robotics.
The increasing automation of industrial processes results in a constantly growing number of sensors and actuators. These need to communicate reliably and quickly over long distances. In addition, they often operate in space-critical or hard-to-access areas. As well as requiring a stable power supply, they also need a standardised connection to higher-level systems β from the field level to the cloud.
Single Pair Ethernet (SPE) and the PoDL standardize device connections
Single Pair Ethernet (SPE) is a forward-looking solution that enables Ethernet communication via two wires in a single cable, connecting directly to sensors and actuators. The standardized interface allows the integration of the smallest field devices, which can be operated over long distances (up to 1000 metres) without signal amplifiers. In combination with Power over Data Line (PoDL), data and power can be run over the same cable. This eliminates the need for additional power lines and significantly reduces cabling costs β a decisive advantage when integrating sensors, detection modules, or actuator systems.
Typical applications:
Temperature, pressure and proximity sensors
Barcode and image processing systems
Actuators, valves and dosing systems
HMI elements and operating units at field level
Lean, connected and ready for the future
SPE and PoDL provide an efficient, space-saving and scalable infrastructure for sensors and actuators. Whether in robotics, building automation or networked production environments: This technology enables the integration of smart devices in line with the principles of Industry 4.0.
Rosenberger collaborates with leading companies from the connector industry, automation technology and the cable sector as part of the Single Pair Ethernet System Alliance. The goal is to further develop and promote Single Pair Ethernet technology. Through close cooperation and focused knowledge sharing, partners from around the world are combining their expertise to drive its advancement and adoption of SPE technology across various applications. Together, we are shaping and driving this future-proof Ethernet technology.
SPE transmits both data and power (Power over Data Line β PoDL) via a single twisted pair instead of four pairs used in traditional Ethernet. This enables simpler, lighter, and more cost-efficient network infrastructures - from the field level to the cloud.
Yes, SPE is compatible with classic Ethernet architectures. By using media converters or switches with SPE ports, it can be integrated into existing networks. Standardized SPE connectors ensure interoperable and seamless communication.
The right connector depends on the application environment. For consistent and future-proof communication, standardized SPE connectors should be used.
Non-standard versions can be suitable for specialized use cases, but standardized SPE connectors according to IEC 63171-7 ED2 ensure long-term compatibility, interoperability and investment security.
Yes. Power over Data Line (PoDL) allows simultaneous transmission of data and power over the same pair of wires.
This eliminates the need for separate power supplies and simplifies network design.
On the hardware side, compatible PHYs, connectors, and cables are required. On the software side, no changes are necessary, as the Ethernet protocol remains the same.
SPE provides advantages in numerous industries, including:
The SPE ecosystem is growing: the first sensors, actuators, and controllers with SPE interfaces are already available. An increasing number of manufacturers are integrating SPE ports, particularly into industrial and IoT devices.
