Crimping as instructed – this is how it's done

If you want durable crimp connections, you can't afford to make mistakes. For a real quality crimp, you need craftsmanship, coordinated tools, and matching wire-end ferrules. There are also international standards and regulations that set out criteria for a perfect crimp connection. These include DIN EN 60352-2, which also describes the advantages of crimping, how to achieve the necessary tensile strength, and how to avoid typical mistakes. Want to know more? We have compiled the most important information on crimping in our whitepaper.

Do's and don'ts in crimping

There are many things you can do wrong when crimping. It starts with the cutting of the conductor. A clean, right-angled, and above all crush-free cut is the best basis for the crimping process. Then remove a piece of the conductor insulation – without damaging the conductor. How much insulation to remove depends on the terminal or contact used. After stripping the insulation, a suitable contact or wire-end ferrule can be crimped onto the end of the cable.

The following DO's and DON'Ts should be observed for the perfect connection:


Formation of cracks at the sides.Sides split open


Formation of cracks at the impressions of the crimping jaw


Crimping asymmetrically Burr formation on one side


Single conductor squeezed off


Single conductor pushed back


Let conductor strands protrude approx. 1 to 2 mm from the copper tube

PZ 2.5 – the smallest professional crimping tool for wire end ferrules


The handiest way to crimp

With the PZ 2.5, Weidmüller has developed a compact crimping tool especially for wire-end ferrules in the cross-section range from 0.14 to 2.5 mm². By focusing on small cross-sections, it was possible to keep the size, weight, opening width, and actuating force of the new tool small – without compromising on crimp quality. The result is currently the smallest professional crimping tool for wire end ferrules on the market.

  • 30 % smaller grip width
  • 30 % smaller opening angle
  • 30 % less weight
  • Perfect ergonomics
  • Best crimp quality
