Harting has launched the Han HC DoubleContact Technology series, which utilizes a dual-path design to increase current capacity by 20 percent compared to legacy standards. This product line is currently available for industrial use.
Why it matters
By increasing the effective contact area, these connectors allow engineers to reduce the footprint of electrical systems without sacrificing performance. This advancement addresses the ongoing industry demand for smaller, lighter, and more thermally efficient power infrastructure.
Laboratory testing confirms the new contacts carry up to 20 percent more current than prior standards, expanding upon current HC-Modular ratings of 250 A, 350 A, and 650 A.
The players
Harting
A German manufacturer specializing in industrial connectivity, power distribution, and data transmission components for robotics and factory automation.
The details
The technology works by splitting current between an internal pin in the socket and a surrounding tab, which together provide a larger effective contact surface area. To manage mechanical stress, the design features rotatable contacts that lock into the insulating body, allowing the connector to rotate freely and compensate for cable loads. The system also includes integrated touch protection on both the pin and socket sides to improve safety during assembly.
Timeline
October 13, 2026: The Han HC DoubleContact Technology series was officially launched.
The Tech Race
This release updates the performance capabilities of the established HC-Modular system. It marks a push to improve power density in robotics and automation hardware by iterating on the fundamental contact architecture.
Engineers and system integrators can now select from these new performance classes to optimize power delivery in industrial robotics and machinery. By choosing these connectors, designers can avoid the need for oversized components, leading to lighter and more compact mechanical assemblies.
The takeaway
The move to double-contact architecture represents a clear shift toward higher power density in standard industrial connectors. Engineers should monitor integration documentation to see if these components allow for the downsizing of existing power supply form factors in upcoming hardware iterations.
