The 19th Connector User Conference in Würzburg once again provided a central platform for exchange between research, development, and industrial application in the field of connection technology. With a combination of technical fundamentals, in-depth specialist presentations, and practical applications, the event was aimed at experienced engineers as well as young professionals and career changers.
Right at the start, the so-called PreConference provided sound basic knowledge. The content ranged from contact physics and materials science to plastic-compatible design and the importance of surface coatings. The topic of electromagnetic compatibility (EMC) also played an important role – an aspect that is becoming increasingly relevant in complex electrical systems. This introduction proved to be a valuable foundation for a deeper understanding of the subsequent technical presentations, especially for newcomers.
A special highlight on the first day was the “Poster Slam.” Six young scientists each presented their research in five minutes – clearly, practically, and concisely. The audience ultimately chose Konstantinos Panos as the winner. His work on X-ray fluorescence measurement technology for nickel-phosphorus coatings impressed with its scientific depth and high practical relevance.
The second part of the congress focused more closely on current market trends and technological developments. The topic of Single Pair Ethernet (SPE) played a central role. In several presentations, experts from Phoenix Contact, Rosenberger, and others demonstrated how SPE functions as a key technology for industrial digitalization, offering advantages in terms of weight, space requirements, and data transmission. The presentations made it clear that SPE is not only suitable for new applications, but can also efficiently complement existing cabling standards.
Sustainable material strategies and resource conservation were also discussed. In particular, the role of the metal recycling industry, i.e., the recycling and recovery of raw materials such as copper and tin, showed how strongly ecological requirements are now also finding their way into connection technology. Technological innovations such as media-tight connectors for battery systems and laser-structured contact surfaces also illustrated how much the industry is focused on precision, quality, and service life.
Freya Stonawski from Lapp Holding SE gave a groundbreaking keynote speech. She highlighted how innovation management must be structured today in order to make companies more agile, creative, and at the same time more structured. Her key message: Innovation requires not only ideas, but also flexible structures and entrepreneurial courage.
The congress program was complemented by numerous workshops and networking opportunities. Participants were able to learn about design guidelines, digital simulation methods, and AI-supported product development in a practical way—topics that are becoming increasingly important in the development and testing of connectors.
Conclusion:
The 19th Connector Congress impressively demonstrated how dynamically the field of connection technology is developing – caught between miniaturization, sustainability, digitalization, and system integration. The exchange between industry, research, and young talent makes the event an important source of inspiration for the industry.
