HARTING releases new Han®4B series connectors
HARTING Technology Group officially launched the Han® 4B series of industrial connectors. The HARTING Han size 4 series now includes three products: Han® 4B, Han® HPR 4, and Han-Eco® Modular 4. This series precisely fills the size gap between the existing Han® 3A and Han-Eco® 6B, providing engineers in industries such as mechanical manufacturing, robotics, energy, and rail transportation with a new option that balances compact size with high current carrying capacity.
Solving a Long-Standing Industry Selection Dilemma
The launch of the Han® 4B series directly addresses this industry pain point. While retaining the same two-module capacity as the 6B, this series reduces the panel opening size by 20% (Han® HPR 4 can be reduced by 40%), while achieving a target price lower than the 6B, providing engineers with an ideal solution of 'smaller size, lower cost, and no performance reduction'.
Five Key Technological Highlights Leading Industry Innovation
Compact Design, Freeing Up Panel Space
The Han® 4B panel opening is reduced by 20%, and the Han® HPR 4 achieves an even greater reduction of 40%, allowing for more flexible enclosure design and enabling more interfaces to be placed on the same panel.
Bridging the Gap Between Two Standards: The existing larger Han-Eco® 6B cannot meet the needs of all energy applications, while the smaller Han® 3A cannot handle the required 70A current.
Compatible with Over 100 Modules: Modular Combination Units
Innovative Snap-on Frame Concept
The Han® HPR 4 shares a unified frame with the Han® 4B, featuring push-in wiring technology (PE grounding supports a maximum wire diameter of 6mm²), significantly improving field installation efficiency. Integrated coding effectively prevents mis-insertion and ensures system safety.
Lightweight design, suitable for rail transit and sports applications.
