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 ET 200SP HA.
