SPE Competence

We are proud to be part of the Industrial Partner Network for Single Pair Ethernet. We are fascinated by the ease of use of this technology. This concept will certainly be an accelerator for IoT solutions: open communication solutions, high efficiency, real-time communications and, most importantly, all within a standardized echo system. This technology will take us one step closer to green electronics. Our contribution to the network is magnetic solutions, e.g. a specially designed SPE transformer.
