HARTING's Han-Eco series comprises robust connector housings made of glass-fiber reinforced high-performance plastics. The series has established itself on the market thanks to its ability to offer advantages such as weight savings and savings in time during assembly and installation. The monoblock inserts have been developed for use in the hoods and housings from the Han-Eco series. They have also managed to retain the proven Han-Eco "click and mate" snap-in function, i.e. the simple and completely tool-free mounting of the insert.

A special feature of the Han-Eco monoblocks is that they achieve up to 67% higher contact density compared to Han^® standard screw inserts of the same size. The inserts feature a pre-leading PE contact (ground) and the possibility of a six-fold coding system. This results in contact numbers of 10+PE, 14+PE, 20+PE, and 28+PE for the respective four sizes. Moreover, it is also possible to combine a monoblock with modules from the Han-Modular^® series in a housing from the Han-Eco series. Another possibility for use is in the Han-Modular docking frame. The contacts are based on the proven Han E contacts with screw termination. The monoblocks have a rated voltage of 500 V and a rated current of 16 A. The cable connection cross-section is 0.75 mm² (AWG 18) minimum and 2.5 mm² (AWG 14) maximum.
