Note
Wire-end ferrules
Optimum results with respect to a high-quality and permanent electrical connection with
maximum conductor pull forces at the same time can be achieved by using crimping dies,
preferably with smooth surfaces, which are provided, for example, with rectangular and
trapezoidal crimp 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 unsuitable.
Permissible cable temperature
Note
Permissible cable temperatures
At the maximum ambient temperature of the PN/MF Coupler, you must select sufficiently
large wire cross-sections so that the permissible cable temperatures are not exceeded.
Examples:
• At an ambient temperature of 60° C, a current of, for example, 4 A per wire and a cross-
section of 1.5 mm² Cu, a connecting conductor must be rated for a temperature range of
at least 90° C.
• At an ambient temperature of 60° C, a current of, for example, 2 A per wire and a cross-
section of 1.5 mm² Cu, a connecting conductor must be rated for a temperature range of
at least 80° C.
