Makeperfect crimping the rule. Because with every truly durable crimp connection, you make installations more reliable and safe. You also save an infinite amount of time during installation. That's provided you use Weidmuller's high-quality precision crimping tools. They enable you to quickly and easily make perfect crimp connections that last and comply with all international standards and regulations. And because every user is different, we provide you with a wide selection of ergonomic products. You are guaranteed to find the right tool in our diverse range of mechanical crimping tools.

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.

In field operations, there is often little space in the toolbox. That's why multifunctional tools like our Stripax Plus are useful. With this tool, cutting, stripping, and crimping are quick and easy.

In many installations, there is very little space in the control cabinet. In addition, many crimping operations usually have to be carried out in the shortest possible time. That is why we have now added a world first to our PZ 6 ROTO crimping tool family.

What is crimping? How do you make a perfect crimp connection? With which tools do you achieve the best results? These and many other questions about crimping are answered in detail in our whitepaper.

Full test schedule covers all components and materials, including exotic ones. Connections made with solid wires, nickel, steel, stainless steel or materials exceeding the tensile strength of 600 MPa may be used.

The Basic test schedule entails just pull out force test on 20 samples and 20 cycles of current loading on another 20 samples while the Full test schedule requires pull out force test on 16 samples, an intensive current loading test (500 cycles!) on 8 samples and climatic tests, including temperature rapid change, dry heat and climatic sequence (dry heat, damp heat, cold) on 16 samples.

IEC Standard gives other recommendations on components regarding both cases: total contact surface between components must be maximum (keeping in mind the splice length and configuration aspect); materials and finishes must be as close as practicable in electrogalvanic series of metals; very hard and very soft materials combination is not desirable for comparable deformation in both the conductor and crimp barrel, etc.

It may be concluded that the Full test schedule presented in IEC 60352-2 International Standard opens the gate for various connections whatever the components and materials are. Being equipped with this instrument, we know how to do best connection so that fine results in laboratory pass into reliable connections in the field environment.

For reference, the IEC (International Electrotechnical Commission) is a global organization for standardization in the field of electrical, electronic and related technologies, systems and services founded in 1906. It is one of three sister organizations (next to ISO and ITU) that develop International Standards.

Often, being able to produce large numbers of reliable connections quickly is important in industry and in trade. The crimping process is well-suited to these kinds of tasks. If a crimp is executed correctly, it is preferable to a soldered connection and can withstand even high mechanical loads. However, crimping correctly is more complicated than you might initially think. Correct crimps fulfil standard DIN EN60352-2. This standard defines basic requirements and contains important recommendations, on which the following practical tips are based.

During crimping, a conductor and connecting element are connected via a pressing process. If the crimp is executed correctly, it creates a homogeneous, non-detachable connection. Essential requirements for crimp connections are defined in DIN EN 60352-2. It also describes testing methods and provides important application information. To produce a long-term, reliable crimp connection that conforms to the standard, the conductor, contact and tool must be optimally tailored to work together. In addition, good preparation is essential for every crimp. Each crimp must be completed using the right tool. We address the individual steps briefly in the following section.

Different pressing shapes are available to crimp wire-end ferrules. We differentiate between trapezoidal, square, hexagonal, and Weidmller crimping dies. All of these have specific advantages and disadvantages. Therefore, you should always select a pressing shape in consideration of the later application.

Most crimp connections are executed manually using classic crimping tools. We differentiate between crimping tools with fixed or exchangeable dies. There are also single- and multi-station tools. You can use single-station tools to process all diameters approved for the tool without additional settings. Multi-station tools include multiple crimping stations for different diameters. With both types, it is important to make sure that the wire-end ferrules are crimped in the appropriate station. For perfect results, it is best to use crimping tools according to DIN 41641-1 from the Weidmller portfolio. With standardised tools, you can complete at least 50,000 crimping cycles without any reduction in quality. However, regular maintenance and testing is urgently recommended.

Cutting Preparation for a crimping process begins with cutting the conductor correctly. It is important to execute a smooth and straight cut, without deforming the conductor. Shearing, crushing, or pulling out the conductor must always be avoided. You can achieve top-class results with professional cutting tools from Weidmller.

After cutting, the conductor insulation must still be removed completely at a defined length without damaging the conductor. Here as well, it is important to work cleanly. With professional Weidmller stripping tools, you can achieve consistently good results in accordance with DIN specifications. They are optimally tailored for the insulation and wire cross-section and ensure error-free processing.

Quality assurance DIN EN 60352-2 recommends using tools and crimp contacts from the same manufacturer. This is the best way to guarantee a consistently high quality of workmanship. Tools and contacts are perfectly coordinated to work together, and available in a wide selection. In addition, crimping tools are developed so that many typical crimping errors are avoided from the outset. They can even compensate for slight fluctuations in the conductor configuration. If you are using exotic conductors, however, you should test the crimp quality very carefully at the start of a project. As your reliable partner, Weidmller offers suitable certification services for this purpose.

HARTING offers a comprehensive portfolio of crimping tools, ranging from simple mechanical tools to rather sophisticated crimping machines optimised for the production of high quantities. All these tools process produce crimp connections of a consistent high quality meeting the relevant standard for this area, the DIN EN 60352-2.

Using the crimping crimp technique, the conductor ends and the conductive termination area of the contacts are crimped in a way that a homogenous, electrically conductive areas is are formed. The quality of a crimp connection is determined by the stability and conductivity of the resulting compound. In addition, a perfect crimp connection is gas-tight and therefore corrosion-resistant.

Since the contacts are equipped with deformable elastic press-in zones at certain positions an optimal connection is processed by pressing-in the contact into the PCB hole. HARTING offers suitable process-optimized tool systems, ranging from simple hand-lever presses to semi-automatic, servo-electrically operated press-in machines. There are large numbers of tools and tooling systems for the respective product groups.
