Note
Ferrules
You can achieve optimum results with respect to a high-quality and durable electrical
connection with maximum conductor extraction forces through the use of crimp shapes,
preferably with smooth surfaces, as is ensured for example with rectangular and trapezoidal
crimp cross-sections.
Due to the variety of crimp shapes used in industry, we recommend other shapes on request.
Crimping dies with a pronounced wave profile are unsuitable.
