Communication via SPE

Single Pair Ethernet – Direct from the sensor to the cloud

Time-consuming installations are now a thing of the past. After all, the new sensors with SPE from JUMO enable you to connect directly to the cloud. For the power supply and data transmission, SPE sensors require only a single pair of wires, making installation simple and straightforward.

SPE: Your benefits at a glance

  • Consistent concept through uniform, Ethernet-based communication from the sensor to the cloud
  • Future-oriented key technology for Industry 4.0 and IIoT
  • Reduced cabling effort due to reduction to only one wire pair
  • Flexible installation due to ranges of up to 1000 m
  • Power supply via Power over Data Line (PoDL), no separate power supply required


Communication via Single Pair Ethernet

What is Single Pair Ethernet (SPE)?

The direct path from the sensor to the cloud

SPE is an Ethernet-based communication that forms the basis for a wide range of transmission protocols. The consistent concept enables direct communication between the sensor and the cloud, which allows individual stages of the automation pyramid to be combined and applications to be simplified.

How does Single Pair Ethernet work?

High flexibility with low cabling effort

Transmission speeds of up to 1 Gbit/s and cable lengths of up to 1000 m allow high flexibility with simultaneous high transmission rates. By using only one pair of wires ("single pair"), the cabling effort is considerably reduced and existing cabling can continue to be used. In addition, the individual sensors are supplied with power directly via the SPE line (PoDL = "Power over Data Line"), which further reduces the installation and cabling effort.
