Connector systems with insulation displacement and crimp technology require suitable cables and accurate processing. In order to assure safe function of the connectors they must be processed with Lumberg harnessing equipment (series 97), according to Lumberg processing instructions, using cables approved by Lumberg. Do not hesitate to contact us if you have any questions!
The cables listed here have been tested in the laboratory and have been approved suitable for the specified connector type. Lumberg cannot assume warranty for possible modifications on the part of the cable manufacturer. It is the user’s responsibility to ensure the compatibility of the chosen components and their appropriateness for the intended application.
