In order to create an optimal crimped connection the standard DIN 46228 recommends to use tools and
contacts of the same supplier (e.g. Weidmüller). Only by doing this can a constantly high processing
quality be guaranteed. Weidmüller offers a matching product portfolio that enables you to process
conductors from an electrical and a mechanical point of view providing safe, long-lasting and reliable
connections.
Start with a clean, non-squeezed and burr-free cut (e.g. with KT 8; Art.: 9002650000), then the conductor
needs to be perfectly stripped (e.g. with Stripax; Art.: 9005000000) in order to guarantee that the entire
cross-section is being crimped in the tube of the ferrule. In case of fanned out conductors ends and
referring to DIN EN 60352 it is only allowed to twist the single strands slightly (re-establishing the original
condition).

During crimp process it must also be noted that wire end ferrules are only meant for the usage of fine-
stranded conductors according to VDE 0295 class 5. Deviations must be evaluated. For crimped
connections with wire end ferrules and conductors with a cross-section up to 6 mm
2
(AWG 10) it is
recommended that the single strands should be visible 1 mm out of the copper tube. For cross-sections
larger than > 6 mm
2
up to 2mm. (compare Img. 4).
Additionally, it is essential to select the crimping tool with a suitable crimping shape for the connection
point (compare Img 5; e.g. PZ 6 ROTO L; Art.: 1444050000). When conducting the crimp it is important to note
that the crimp should be placed close to the plastic collar (Img. 6).

When considering all aspects of this technical information a high quality, non-detachable connection is
established between conductor and wire end ferrule.
