HARTING has released its Han HC DoubleContact Technology series, which features a design that allows current to flow through two parallel paths. Laboratory testing confirmed that these connectors carry up to 20 percent more current than previous standards.
Why it matters
This advancement aims to improve thermal performance and reduce contact resistance, allowing engineers to use more compact components in their hardware. By selecting specific performance classes, users can avoid the need for oversized equipment while maintaining high power delivery.
The new contact series includes the DCT CU 18, DCT CU 22, and DCT CU 30 models, which provide a significantly larger effective contact area than older iterations. These connectors utilize internal pins and surrounding tabs to facilitate power transmission while featuring touch protection on both ends.
The players
HARTING
HARTING is a global developer and manufacturer of industrial connectivity solutions including electrical connectors and device interfaces.
The details
The design includes rotatable contacts that lock into the insulating body, enabling the connector to move freely after installation to compensate for mechanical cable stress. This structural change provides a pathway for manufacturers to develop smaller and lighter connector units for industrial robotics and heavy-duty applications.
Timeline
October 13, 2026: The Han HC DoubleContact Technology series was officially launched.
The Tech Race
This development represents a shift toward higher efficiency in industrial power transmission, directly challenging the limitations of the existing HC-Modular connector system. By optimizing contact geometry, HARTING is positioning its technology to replace bulky, less-efficient legacy power interfaces.
Engineers and hardware designers can now implement smaller, lighter connector setups without sacrificing power delivery capabilities. This change simplifies assembly in constrained industrial spaces and may lead to reduced overall weight in robotics and manufacturing equipment.
The takeaway
This technology demonstrates that precision in contact geometry can significantly outperform traditional physical scaling when seeking higher power efficiency. Designers should review the new performance classes to see if their current hardware configurations can be downsized for better weight management.
