Expertise in flexibility and precision
The electrics and electronics of new vehicles are becoming increasingly complex. New assistance systems and individual customer wishes require high-performance solutions up to the variant-rich final assembly.
We rise to this challenge. We manufacture high-quality customized cable sets — quickly, precisely, and flexibly. Parallel to this, we have synchronized and standardized the processes at our worldwide locations. This ensures efficient and transnational project management and a high level of start-up reliability for projects.
With our efficient logistics, we integrate ourselves into the production chain of the vehicle manufacturers exactly according to schedule. Our processes can be flexibly harmonized with those of the customer and adapted at short notice. Our own quality standards are the yardstick, and the satisfaction of our customers is the decisive factor.
Wiring systems & more
As one of the world’s largest manufacturers of wiring harness systems, we supply not only wiring harnesses but also components and electronics.
Development
We see the changes in the automotive industry as an opportunity: together with our customers, we work on trends and solutions for individual mobility.
Wiring Harness system
The nervous system of a vehicle
The development and assembly of wiring harness systems, the linking of all electrical and electronic components within a vehicle, is our core competence. The wiring system transmits electrical power and signals and controls driving assistance, safety and comfort systems via this nervous system.
Thanks to our expertise, we are one of the largest wiring harness system manufacturers in the world and develop customized solutions for individual mobility for our customers. The strength of the Sumitomo Electric Group makes us a reliable partner to the automotive industry — today and in the future.
Key figures ABout the Wiring Harness System
Complex precision, very impressive
A customized wiring system consists of numerous different components. Several thousand parts are installed in the process. These include cables, connector housings and contacts.
The graphic shows an example of the number of parts installed in a wiring harness system of the compact class.
Components
All about the wiring harness system
In addition to wiring harness systems, SEBN also offers the customer a wide range of components. Thanks to our group of companies, we benefit from group synergies and act as a strong system supplier within the group. Our customers are always impressed by the worldwide teamwork with SEBN’s sister companies.
Component expertise in Europe
The business of our sister company SEWS Components and Electronics Europe Ltd. (in short: SEWS-CE) is the development, production, and distribution of all kinds of connectors as well as relay and fuse boxes. These are needed to control and distribute electrical energy to each user in the vehicle. The production facility is located in the Hungarian town Mór. The focus here is on the molding of plastic components as well as the stamping of metal parts and their assembly.
With tailor-made products for various vehicle OEMs (original equipment manufacturers), SEWS-CE is a seamless complement to SEBN’s wiring harness system business in Europe. With development, support, and sales offices in Germany, France and the United Kingdom, SEWS-CE is close to the customer.
Pioneering technology
An outstanding example of cross-divisional cooperation is the SWS competence center in Morocco: all sister companies are located in Morocco and work together on the topics of automation, in-house and high-voltage production. Parallel to this, we are working together on solutions for optimized manufacturing processes and products. The competence center in Morocco not only bundles synergies and unites the companies, it is also a production complex for highly automated parts.
Together with our customers, we work on future-oriented technologies and at the same time offer the innovative strength and stability of a large international group.
Development
Innovation is our driving force
At SEBN, we see the constantly changing challenges in the automotive industry as an opportunity: We use the dynamics of change to better meet the new requirements of our customers. To this end, our teams of engineers and technicians work to identify and analyze trends and develop solutions.
The nucleus for innovations is the Technology Center at our headquarters in Wolfsburg. At the Technology Center, we dedicate ourselves to basic research for future technologies. We implement individual requirements, develop, and build prototypes in close cooperation with our customers and in networking with our competence centers. Each prototype undergoes demanding quality tests. In the laboratory and in simulation, we test our products for durability and resilience and expose them to extreme temperatures and elements before they are included in our product portfolio.
Wiring Harness System Development and Architecture Studies at SEBN
For the future wiring harness system, the scope of electrical functions in the vehicle will increase significantly, driven primarily by the global trends of electrification and driver assistance systems. This complexity and therefore also the size of the KSKs (customer specific cable harnesses) takes design and production to the limit of feasibility.
New E/E architectures and topologies, such as zonal concepts to take up and support this development.
Involved early in the project and together with the customer, SEBN develops the appropriate conceptual and cost-optimized wiring harness system with optimized automation grade in PREEvision to reliably transmit power and signals.
These are our development services
Customer-specific requirements are our benchmark: from concept to production to delivery in sequence, we develop the most diverse technological solutions. This applies just as much to series production as it does to highly individual customized products. Our strength lies in our complexity management. We master a wide range of tasks at the same time. Our product portfolio covers electrical systems, electrical and electronic components for conventional and electrical drive technologies. This also includes low-voltage, multi-voltage, and high-voltage wiring harnesses. Our core business is the wiring harness system. Thanks to the network of Sumitomo companies, we cover the entire spectrum of vehicle electrics and electronics at the same time. This includes, for example, cables, contacts, housings, plastic components, and complex control units.
passion for wiring harness systems
The strength of Sumitomo Electric Group
Current influences, such as higher quality requirements for autonomous driving and the reduction of CO2 emissions, are shaping the transformation of wire harness production. In order to be able to manufacture such a highly complex product fully automatically, SEBN considers the entire value chain. Production processes, procedures and components are thus adapted to the requirements and reinforced by the experience and expertise of the Sumitomo Electric Group.
