Würth Elektronik ICS has created an optimal connecting solution for Getriebebau NORD – one of the leading manufacturers of drive technology – using SKEDD technology, and thus granted the company valuable freedom in component design

Rear connection of the PCB within a limited assembly space was needed to produce the new NORD SK 250E motor starter and SK155E frequency inverter of the NORDAC LINK field distributor series

Rear connection of the PCB within a limited assembly space was needed to produce the new NORD SK 250E motor starter and SK155E frequency inverter of the NORDAC LINK field distributor series. Applying the soldering method that had been used up to that point would have resulted in an additional socket base that would take up too much assembly space and necessitate an additional process step. However, the alternative option of using a separate PCB to connect the cables and connect them to the main circuit board using a board-to-board solution would have required a redesign of the entire product. After comprehensive research, the developer team at NORD decided to opt for SKEDD direct plug-in technology by Würth Elektronik ICS to avoid this considerably higher effort and find the most convenient solution possible. This enables direct connection from the rear side of the PCB as desired, without additional process steps.

SKW connector system as a solution

Together with the experts at ICS, Getriebebau NORD found the optimal solution by using the SKW connector. Its flexibility in terms of assembly design particularly convinced the customer: The SKW connector can generally be plugged in from either side, multiple times reversibly and all over the entire PCB surface. Due to this added value, it is used in the device versions of the NORDAC LINK field distributor, as NORD SK 155E-FDS motor starter and NORD SK 250E-FDS frequency inverter. In addition to the laborious soldering process, the extra base socket is no longer required.

More freedom for product designers

The SKW connectors also successfully passed system qualification, including a shock and vibration test according to IEC60721-3-3. The SKW connector system fully meets the requirements of NORD engineers at ambient temperatures in the range up to +70°C and currents up to 16 A.
“We are delighted to confirm that our SKEDD wire-to-board connector system has increased the level of freedom for product designers and has met all technical specifications,” says Achim Engel, Product Manager for SKEDD at Würth Elektronik ICS.

About SKW connector systems and SKEDD

SKW connector systems offer many advantages due to their direct, reversible plug-in capability, simple assembly and robustness, among other factors. As a straightforward and reliable alternative to soldering and press-fit technology, the patented SKEDD technology allows tool-free connection of components and connectors on PCBs for applications requiring currents of up to 20 A in two-pin, three-pin and four-pin design. The PCB is used as a socket, making a socket base unnecessary and reducing materials and interfaces.
