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. Options are, for example, rectangular or
trapezoidal crimp cross-sections.
Due to the large variety of crimp shapes used in the industry, we will be glad to
provide more recommendations upon request. Crimp shapes with pronounced
wave profile are not permitted.
Equipping
