From the Case Bank
A German industrial electrical systems integrator required cable harnesses for a high-volume annual program but faced sourcing constraints on specified connectors.
The originally specified STOCKO connectors faced procurement limitations, and the required PTC components (EPCOS B59100A1080-A40) had a long 12-14 week lead time, threatening the overall project timeline for a 200kpcs/year program.
Proposed Lumberg connectors as a qualified alternative to STOCKO. Provided detailed specification comparisons and emphasized Lumberg's shorter MOQ and better delivery times to offset the PTC lead time bottleneck, while remaining transparent about the slightly higher price point of the alternative.
The customer accepted the alternative for evaluation, agreeing to sample the Lumberg-based assemblies, which kept the high-volume annual program viable despite initial component sourcing bottlenecks.
- 100kpcs/year per product (200kpcs total annual volume)
- PTC model: EPCOS B59100A1080-A40
- PTC lead time: 12-14 weeks
- Connectors evaluated: STOCKO vs. Lumberg
Prototype to Mass Production — Smart Hardware
A US industrial smart-device distributor needed to scale a diverse range of custom cable assemblies from initial prototyping to high-volume mass production.
Frequent design changes (cable lengths, shielding requirements, connector models) combined with a wide range of order volumes — from dozens of samples to tens of thousands of units across 10+ SKUs.
Provided agile sample turnaround and flexible manufacturing processes, accommodating rapid design iterations while smoothly transitioning to volume production for multiple SKUs (Float sensor, Ethernet, Speaker cables).
Secured a multi-million dollar annual revenue program across multiple product lines, demonstrating capability to handle high-mix scaling from prototype to mass production.
- Order volumes: dozens (samples) to 20,000+ units per SKU
- 10+ active SKUs managed simultaneously
- Multi-million dollar annual program secured
From R&D Samples to 10K Annual Volume
A subsidiary of a global currency-technology OEM required custom cable assemblies for banknote-processing R&D, starting with small prototype batches and scaling to mass production.
Managing the transition from 10-20 piece sample orders to 500-unit MOQ mass production while maintaining consistent quality and meeting aggressive 2-3 week lead times.
Provided flexible sample manufacturing via streamlined payment channels for fast procurement, followed by structured mass production setup with MOQ 500 sets, accommodating annual volumes of 5-10K units.
Successfully transitioned from prototype to mass production, securing a multi-year repeat program with annual volumes reaching 5,000-10,000 units.
- Sample qty: 10-20 pieces
- Production MOQ: 500 sets
- Annual volume: 5,000-10,000 units
- Standard lead time: 2-3 weeks
15-Day Rush Delivery for EV Harness Prototype
A US EV automotive OEM required an urgent NPI prototype run for a new vehicle harness package with Amphenol connectors.
50 units needed within 15 days of PO issuance, requiring rapid procurement of authorized Amphenol connectors alongside expedited manufacturing.
Fast-tracked the production schedule, secured Amphenol connector authorization and procurement, and coordinated expedited logistics to meet the 15-day deadline.
Delivered the initial prototype batch on time, securing the customer's trust and a follow-on multi-PO repeat program for the vehicle platform.
- 50 units delivered
- 15-day lead time (PO to delivery)
- Amphenol authorized connectors
- Follow-on multi-PO repeat program secured
Custom Cable Assembly FAQ
To provide an accurate quote, we need: drawings or schematics (if available), connector part numbers or requirements, cable specifications (type, gauge, length), quantity requirements, and any special requirements (shielding, IP rating, temperature range). We can also work from concept descriptions or samples if detailed drawings aren't available. Most quotes are returned within 24 hours.
Yes, our engineering team provides full design support from concept to production-ready documentation. We offer connector selection guidance, cable sizing optimization, routing analysis, and design for manufacturing (DFM) review. We create complete technical drawings and BOM for customer approval before production.
We have no minimum order quantity — you can order as few as 1 piece for prototyping. This allows you to validate your design before committing to volume production. We support the full range from 1pc prototypes to 500,000+ annual programs.
Prototype turnaround is 48 hours for simple assemblies, 5-7 business days for complex designs. Standard production lead time is 2-3 weeks. Expedited service is available depending on complexity and component availability. We provide specific lead times with every quote.
Our facilities are ISO 9001 and IATF 16949 certified. We manufacture to IPC/WHMA-A-620 workmanship standards. Depending on application, we support UL, CSA, CE, RoHS, and MIL-SPEC requirements. All assemblies undergo 100% electrical testing (continuity, hi-pot, insulation resistance).
We source from all major connector manufacturers including Molex, TE Connectivity, JST, Amphenol, Hirose, Phoenix Contact, Deutsch, and 12+ other brands. We can also work with customer-supplied or customer-specified components.
Pricing depends on connector complexity, cable type, length, shielding, and volume. Simple 2-connector assemblies start around $2-5/unit at volume. Complex multi-branch harnesses with overmolding range $15-80+/unit. We provide detailed cost breakdowns with every quote — no hidden tooling fees for standard assemblies.
Yes, we manage the full lifecycle from 1pc prototypes through high-volume mass production (500,000+ units/year). Many of our customers start with small prototype batches for design validation, then scale to production volumes. Our flexible manufacturing supports high-mix, low-volume (HMLV) as well as dedicated high-volume lines.
Every cable assembly undergoes 100% electrical testing including continuity verification, hi-pot (dielectric withstand), and insulation resistance. Additional tests available include pull-force testing, flex cycling, environmental stress screening, and custom functional tests per customer specifications.
Absolutely. We support agile NPI (New Product Introduction) processes with rapid design iteration capability. Our engineering team accommodates changes to cable lengths, connector models, shielding requirements, and pinouts throughout the development cycle without restarting the quoting process from scratch.
