Custom Cable Harnesses

What a custom cable harness really is — and why you need one

A wire harness (sometimes called a cable harness) bundles multiple conductors into a single, organized unit with connectors and terminals. Instead of routing dozens of loose wires through your product, the harness arranges them neatly and adds protective sleeving or insulation. This organized assembly:

• Simplifies installation: harnesses are pre‑tested and ready to drop into place; they eliminate the need to run and check individual wires.

• Improves safety and reliability: bundling wires reduces the risk of short circuits and improves signal quality; protective coverings resist moisture, heat, chemicals, vibration and abrasion.

• Optimizes space and weight: compact harnesses maximize space in crowded enclosures or lightweight platforms.

• Reduces lifecycle costs: faster assembly and improved reliability lower labor and warranty costs; custom harnesses also minimize downtime by using robust materials.

These advantages make custom harnesses indispensable across sectors such as medical devices, automotive, robotics, aerospace and industrial machinery.

Why choose BACH INDUSTRY AG

Competitor research shows that quality harness suppliers differentiate themselves through design precision, rigorous testing and adherence to standards. BACH INDUSTRY AG meets and exceeds these benchmarks:

• Swiss engineering & EU logistics: Our production is anchored in Switzerland and the DACH region, providing robust quality control, predictability and streamlined customs paperwork.

• Integrated design-to-delivery: We handle the full lifecycle—from CAD and DFM reviews to harness prototyping, testing and mass production—so your project moves smoothly from concept to series ramp-up.

• Workmanship to IPC/WHMA‑A‑620: We build to the industry’s consensus acceptance standard for cable and harness assemblies, ensuring proper crimp geometry, insulation support and no nicks or broken wires.

• Extensive testing: Every harness undergoes 100 % continuity checks, insulation resistance and HiPot testing; crimp samples are pull-tested and microscopically inspected.

• Material & connector expertise: We offer conductors from 30 AWG to heavy gauge, insulation materials like PVC, XLPE, PTFE and silicone, and connectors from TE, Molex, JST and Deutsch to Lemo and Amphenol. Shielding options (foil, braid, combo) mitigate EMI.

• Compliance & certifications: Operations run under ISO 9001 and IATF 16949, with optional ISO 13485 (medical) lines. We provide EN 10204 3.1 certificates on request and support RoHS/REACH, UL AWM and other regulatory requirements.

The benefits of custom harnesses—evidence from the industry

Industry analyses consistently highlight several advantages of tailor‑made harnesses. BACH INDUSTRY AG incorporates these benefits into every project:

1. Precision fit & scalability: Custom harnesses are engineered to exact specifications, ensuring proper fit and easy upgrades. Scalable designs accommodate future technology additions without a full overhaul.

2. Space optimization: Bundling and routing wires in a harness maximizes space and reduces clutter, particularly in robotics and consumer electronics.

3. Enhanced performance & reliability: Custom harnesses use high-quality materials and optimized layouts to improve signal integrity and reduce electromagnetic interference. They last longer in their intended environment, reducing failure rates and unplanned downtime.

4. Cost-effectiveness: Although custom harnesses may cost more upfront, they reduce assembly time, minimise errors and avoid expensive rework, delivering significant lifecycle savings.

5. Safety & compliance: Custom harnesses meet industry‑specific standards (IPC/WHMA‑A‑620, ISO 9001 etc.) and can incorporate special jackets or shielding for harsh environments. They’re designed for enhanced safety in critical applications like renewable energy, defense and transport.

6. Faster installation & maintenance: Pre‑configured harnesses with color‑coding, printed labels and heat‑shrink markers speed up installation and troubleshooting.

7. Branding & personalization: Companies can include logos, color codes and custom labeling on harnesses to reinforce branding and ease identification.

Our capabilities & offerings

BACH INDUSTRY AG supplies both wire harnesses and cable assemblies, combining them where needed. We support:

• Prototype to series production: Rapid prototypes for design verification and scalable manufacturing for high volumes.

• Harness types: Engine, dashboard, battery, sensor, robotics and custom harnesses for industrial panels.

• Materials & accessories: Copper (standard or tinned), aluminum for weight-sensitive designs; insulation in PVC, XLPE, PTFE, silicone; protective sleeving (braid, conduit, heat-shrink) and hardware (labels, clips, grommets).

• Testing & inspection: Continuity checks, HiPot and insulation resistance, crimp force monitoring and cross-section analysis; we adhere to IPC criteria for insulation crimp tabs, wire condition and connector retention.

• Advanced features: EMI shielding, overmolding, strain-relief boots, IP‑rated seals; harnesses integrated with PCBs and sensor circuits.

Typical engagement process

1. Share your package: Provide 3D models or drawings (STEP/PDF), pinout tables and connector part numbers, environmental conditions (temperature, chemicals, IP rating), target quantities and desired standards.

2. DFM review & quotation: We deliver manufacturability feedback, propose alternate materials or connectors, and supply cost/lead options (standard vs. expedited).

3. Prototype & validation: We build golden samples, supply ballooned drawings and test reports, and adjust designs as needed.

4. Release & supply: Once validated, we lock processes, provide traceability and certification documents, and establish call-offs or Kanban/VMI programs for ongoing supply.
