The Han® 1A series offers a compact, robust and universally deployable rectangular connector system for transmission in all lifelines of Industry 4.0 (i.e., data, power, signals). Industrial devices are becoming smaller and smaller. Therefore, miniaturized connectivity solutions are strongly required, for example in engineering and robotics. In order to make optimal use of the available installation space, rail vehicle designers look for minimized interfaces. With the Han® 1A, HARTING presents a small and powerful interface that clearly undercuts the dimensions of the smallest rectangular industrial connector so far, the Han® 3A.
