Single Pair Ethernet

Single Pair Ethernet

Ethernet finally goes the distance

Consistent data transmission in the Industrial Internet of Things.

Single Pair Ethernet stands for parallel, high-performance transmission of data and power via Ethernet through a single double wire via Power over Data Line (PoDL).

Phoenix Contact has launched compact device and cable connectors for the Single Pair Ethernet standard. The standardized SPE interfaces are ideally suited for efficient data transmission in factory and process automation. The application-specific, reduced cabling is therefore the basis for future-proof Ethernet communication from the field to the cloud.

Your advantages

  • Future-proof: Standardized connectors and cables in accordance with IEC 63171-2 (IP20) and IEC 63171-5 (IP67)
  • Cross-application: Ranges of up to 1,000 m, data rates of up to 1 Gbps, and powers of up to 50 W
  • Efficiently cabled: Plug and Play, even in existing cabling infrastructures
  • Compact: Pin connector patterns for single and multi-ports enable high packing densities
  • Easily integrated: Male and female versions for established inductive sensors and flying leads

Single Pair Ethernet technology

The evolution of 4- and 8-wire cabling systems toward simple and secure two-wire cabling has begun – and the result is Single Pair Ethernet.

Ethernet has already been the leading communication and network protocol in LAN applications since the 1980s, and since then it has been constantly advancing into new fields of application. Ethernet allows the seamless transmission of information via TCP/IP, and is viewed as the application-neutral communication protocol for local IoT networks. The unique compatibility of Single Pair Ethernet between new and old generations is the basis for the future.

Standardized pin connector patterns as the basis for future-oriented network communication  

Standardized pin connector patterns as the basis for future-oriented network communication

Standardized pin connector patterns form the basis for the barrier-free networking of the most diverse components, cables, and connectors. Here, Phoenix Contact is driving progress decisively with the development of a standardized pin connector pattern – from the IP20 to the IP6x connector.

In the long run, SPE will replace classic serial bus systems. Use a multifunctional pin connector pattern from the office to the sensor.

The M1 I1 C1 E1 pin connector pattern in accordance with IEC 63171-2  

The M1 I1 C1 E1 pin connector pattern in accordance with IEC 63171-2

The pin connector pattern M1 I1 C1 E1 has been developed for building automation in accordance with IEC 63171-2. This pin connector pattern makes it possible to connect up to four times as many devices as you can with existing passive infrastructure. This standard is often used in office buildings.

The M2/3 I2/3 C2/3 E2/3 pin connector pattern in accordance with IEC 63171-5  

The M2/3 I2/3 C2/3 E2/3 pin connector pattern in accordance with IEC 63171-5

The M2/3 I2/3 C2/3 E2/3 pin connector pattern in accordance with IEC 63171-5 has proven itself in industrial applications, even in harsh field environments. The pin connector pattern can be integrated into all conventional and standardized connector versions.

MICE is an abbreviation that describes the external conditions of an Ethernet interface.

  • M = Mechanical robustness
  • I = IP properties
  • C = Chemical and climatic resistance
  • E = Electromagnetic stability
