D-Sub connectors and contacts

Inotec’s ambition is to ensure a maximum shielding performance, robustness and reliability for D-Sub interconnections. As crimping of D-Sub contacts is still the most reliable technology regarding safe assembly and contacting quality, Inotec has developed its own program of high-end D-Sub crimp connectors and contacts.

Our high-precision turned contacts made of special copper alloys are finished with premium quality gold plating on a nickel base layer. The dimensionally accurate and reliable manufacturing process combined with a 1,3 μm gold layer in class 1 quality permits minimal contact resistances of less than 3 mΩ. The trapezoidal shaped collar of our connector shells is shielding the contacts against disturbances through electromagnetic fields. In order to optimize the grounding contact of the shells, Inotec provides an alternative type with indents on male and female connector shell.

As a matter of course, in addition to the classical crimp connectors, Inotec also offers premium connectors as solder-cup, dip-solder or other versions.
