Snap In connectors for motor controls allow robotic assembly
27 November 2025 
Schneider Electric has adopted Weidmüller’s Snap In connection technology for its TeSys motor management system, allowing stripped conductors to be inserted directly into terminals without any preparation. The preloaded terminals can be used immediately, simplifying and accelerating the wiring process. The tool-free connection technology also opens up the possibility of robotic wiring of motor controls – a capability which Schneider demonstrated at its recent Innovation Summit in Denmark.
Since Weidmüller launched the Snap In technology in 2021, it has changed the way electrical components are wired. For installers and panel-builders, it avoids the need for ferrules, crimping, tools and time-consuming preparation. It also ensures safety – incorrect contacts as a result of inadequately inserted conductors are said to be “almost impossible”.
The technology is re-usable, and is suitable for maintenance and retrofitting activities. A green “pusher” indicates the switching status of the terminal and provides visual, haptic and acoustic feedback. An audible “click” confirms the secure contact. The contact can be released using a screwdriver.
The technology can be used in confined places, and by non-expert personnel. Weidmüller says that wiring times can be reduced by up to 75%.
Since Weidmüller launched the Snap In technology, it has used it in many of its products, including its Klippon Connect terminal blocks, Omnimate PCB connectors, RockStar heavy-duty connectors, Push Pull Power connectors and Pro Eco II power supplies. Now, after less than 12 months of development, Schneider has developed suitable sub-assemblies and set up an automated production line to use the technology in its TeSys motor controls. Jürgen Stawartz, vice-president of Schneider’s Power Products business, describes the development as “a real milestone”.
In Denmark, Schneider demonstrated a collaborative robot picking up and inserting wires with conductors up to 6mm2 into TeSys Deca terminals.
