Our Prod­ucts

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.

Expertise in flexibility and precision

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

Supplier Area

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.

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-CEis 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.

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.
