Note
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. Rectangular and trapezoidal crimp cross-
sections ensure this, for example.
Due to the large variety of crimp shapes used in the industry, we can recommend additional shapes upon request. Crimp
shapes with pronounced wave profile are not suitable.
