WOW “ Crimping tools with a spring effect enable reliable compensation of potential size discrepancies between the conductor and the wire-end ferrule “
Crimping requires not only a tradesman’s skill, but also a suitable crimping tool and the appropriate contacts. The requirements for crimping connections are specified in international standards and guidelines, e.g. DIN EN 60352-2.
An essential quality factor is the tensile strength achieved in the connection, as well as the avoidance of typical crimping errors. However, caution is required: every conductor does not fit every contact and no single tool is suitable for all tasks. After all, the individual production tolerances of conductors and crimping materials do not enable every conductor to be processed with every contact.
A problem can arise when processing wire-end ferrules. If the ferrule originally designed for the nominal cross-section no longer fits the conductor, the crimping dies must compensate for this size discrepancy. This certainly isn’t an easy task if the conductor in fact only measures 2.8 mm² instead of the stated 4 mm², for instance. To compensate, we advise you to use crimping tools with a spring-loaded effect.
