Weidmüller uses this SPS Nuremberg 2025 booth tour to show how cabinet building can be treated as a data-driven, semi-automated production line rather than a manual craft. Robots like “Snappy” work with the Wire Processing Center to cut, strip and crimp conductors, then feed them into SNAP IN terminal blocks that lock with a single click and require no ferrules, making wiring faster and less error-prone. This interview walks through how those mechanics, terminal blocks and software all fit together in real cabinet production environments. https://www.weidmueller.com/en/solutions/technologies/snap_in_connection_technology/index.jsp

HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

From there the tour dives into “next level cabinet building”: automated wiring cells, a rail assembler that populates DIN rails with relays and terminal blocks directly from engineering data, and guidance systems that lead operators step by step through wiring and marking to avoid mistakes. The long-term partnership with Schneider Electric and the TeSys range shows how SNAP IN can be adopted in mainstream low-voltage gear as well. A dedicated area highlights Weidmüller’s ergonomic hand tools and wire processing equipment that combine cutting, stripping and crimping in one motion, connecting today’s demo to a 175-year history that started with mechanical snap fasteners for clothing and evolved into electrical connectivity for industry.
On the automation side, the booth shows how the u-mation portfolio ties hardware and software together: u-remote I/O, web-based controllers such as u-control, and Linux-based platforms like u-OS for edge computing and Industrial IoT. Dashboards visualize energy consumption, machine status and production KPIs, while automated reporting helps factory managers see where bottlenecks or inefficiencies are. Extension modules and open interfaces let OEMs treat control hardware as a modular platform, combining real-time control with data aggregation for analytics, predictive maintenance or cloud integration. Filmed at the SPS trade fair in Nuremberg 2025, the discussion emphasizes openness, from standard fieldbuses to containerized runtime environments.
A large part of the booth is devoted to connectivity across the whole signal chain: PCB and device connectors, feed-throughs for easy maintenance without opening the cabinet, and an extensive range of field connection products. Viewers see M8, M12 and M23 circular connectors, rugged RockStar heavy-duty connectors and push-pull M12 designs that support quick, tool-less mating in harsh environments. High-current interfaces for rail and other demanding sectors illustrate how power, signal and data can be combined in compact form factors, enabling denser cabinets and more integrated machines without sacrificing serviceability.
The highlight on communication is Single Pair Ethernet, presented as the next step in Ethernet-based factory networking. Instead of eight conductors in a traditional RJ45 cable, SPE uses just one twisted pair while still supporting power over data lines (PoDL), up to 10 Mbit/s over 1 km for sensor networks and higher data rates such as 25 or 40 Gbit/s over shorter distances. The smaller connectors, simplified wiring and clear polarity reduce installation effort and error risk, while enabling end-to-end IP communication down to the field device. Combined with Weidmüller’s global engineering presence and strong German R&D base, the SPE and SNAP IN portfolios position the company as a key player in making control cabinets more modular, networked and easy to assemble.
