Note
Ferrules
You can achieve optimal results with respect to a high-quality and durable electrical connection and maximum conductor
extraction forces at the same time by using crimping dies preferably with smooth surfaces. Options include rectangular and
trapezoidal crimping 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 not permitted in the product.
