Note
Wire end ferrules
Optimum results with respect to a high-quality and permanent electrical connection with
maximum conductor pull forces at the same time can be achieved by using crimping dies,
preferably with smooth surfaces, which are provided, for example, with rectangular and
trapezoidal crimp cross-sections.
Due to the large number of crimping dies used in the industry, we can recommend others on
request. Crimping dies with a pronounced wave profile are unsuitable.
