SINGLE PAIR ETHERNET (SPE)
SPE cables and wires for highly flexible and harsh use in industrial environments
The digital revolution is not only resounding throughout the land but hasalready found its way into many companies. In connection with Industry 4.0 the demands on data transmission in real time are growing considerably as well as the rapidly increasing degree of networking in production.
The increasing networking and communication of machine components requires the treatment of larger data volumes that have to be transmitted reliably even under difficult conditions.

How are Single Pair Ethernet cables constructed? How does this compare to classic Industrial Ethernet technology?
Due to the high mechanical and transmission requirements of single pair Ethernet cables, the demands on the design and production are also significantly higher compared to multi-pair stranded Ethernet cables. The exact manufacturing specifications must be met 100 %.
All Single Pair Ethernet Cables are designed as single pair cables (2 x AWG 26/7) and can also be designed as hybrid cables depending on the application. SAB expects a lot of application-related special solutions, e.g. with power supply for motors and sensors. Especially in this area SAB sees itself well positioned and would like to offer individual solutions.
Depending on the application, there are different requirements for the design. For drag chain applications, a permanently flexible design with a specially adapted stranding technique was chosen for the CATLine SPE C-Track cable. For use in robot applications, the design was adapted so that flexible use for a torsional application of +/- 180° can be guaranteed.
Benefits of SPE cables
Compared to a classic 4-pair Ethernet cable, there are space savings up to 30% and weight advantages up to 35%. The potential savings in euros are therefore enormous if you extrapolate the amount of cable laid in km. In the course of a life cycle, e.g. for a railway, this quickly amounts to 6-digit euro sums.
Use in robots & drag chains
According to the current status, SPE does not require more bandwidth than Cat.7A. Single Pair Ethernet cables from SAB have already been successfully tested.
Special solutions for special applications
The production possibilities of SAB do not only include standard types and dimensions but also special cables that are manufactured acc. to the respective requirements of the customer. SAB is able to realize productions already for small batches that are of interest for small or pilot series.
