Chicago-based. Hand-built. Audit-ready. Serving medical, defense, and industrial engineering teams with no minimum order requirements.
Cabelman Interconnect Technologies is a Chicago-based custom cable and wire harness manufacturer specializing in low-volume, high-precision builds for medical, defense, and industrial applications.
We are IPC-A-620 Class 3 certified — the highest standard in the industry — and every assembly we produce is built by hand, inspected under magnification, and tested before it ships.
We work with engineering teams, research labs, and product developers who need a reliable local partner for small batch production. No minimum order requirements. No overseas lead times. Just precise, documented, audit-ready work delivered fast.
Based in Chicago, IL · Serving clients across the Midwest and nationally
Class 3 is the highest workmanship standard in cable and harness manufacturing — required for life-critical medical devices, defense systems, and aerospace equipment. Every assembly we produce meets this standard.
To give small and mid-size engineering teams access to the same quality and documentation standards that Fortune 500 manufacturers demand — without the volume minimums or the wait.
Every job — prototype or production — is built by hand to IPC-A-620 Class 3 standards with full test documentation included.
Hand-built to your specifications. We work from your drawings, samples, or engineering notes to produce assemblies that meet your exact requirements.
From single-branch pigtails to multi-leg harness assemblies, built to IPC-A-620 Class 3 standards with full documentation on every job.
Need two or three samples before committing to production? Fast turnaround, full test documentation, and a signed first article report ready for your review.
Every single assembly is tested before it ships. No batch sampling. No exceptions. Each unit receives a serialized test report covering continuity, insulation resistance, and wiring verification.
Every order ships with a complete audit-ready documentation package. No need to request it separately — it's standard on every job.
We built this company specifically for the customers that large shops turn away — small volumes, tight specs, fast timelines.
Not every shop holds this certification. We do. It is required for life-critical medical devices, defense applications, and aerospace equipment — and it governs how we build every single job.
We do not sample test. We do not batch test. Every single harness we ship has been individually tested and logged. You receive a serialized report that proves it.
Overseas manufacturers quote 12 to 16 week lead times. We build locally in Chicago and can deliver a 100-unit batch in as little as two weeks. When your timeline moves, we move with it.
Whether you need 10 units or 500, you get the same Class 3 quality and the same documentation. We take the jobs that larger shops turn away.
We work directly with your engineering team from drawing review through first article approval and into production. One point of contact. Clear communication. No surprises.
Class 3 is not the default. It is the highest workmanship standard in cable and harness manufacturing, required for life-critical medical devices, defense systems, and aerospace equipment. Most contract manufacturers build to Class 2. We are certified to Class 3 and hold every assembly to that standard — regardless of volume or application.
Traditional contract manufacturers penalize small-volume customers with setup fees, tooling charges, and NRE costs that can reach $1,500 or more before a single unit is built. We engineered our facility specifically to eliminate that model.
Every assembly — regardless of volume — ships with all four of these testing and verification protocols performed and documented at no additional charge.
Every crimp is inspected under stereo magnification to verify wire brush, bellmouth, and insulation window tolerances per IPC-A-620 Class 3.
True crimp height is physically verified using NIST-traceable Mitutoyo Point-and-Blade micrometers on every connector type in your build.
Pre-batch pull-force testing ensures life-critical mechanical bonds meet specification before your production order is built. Results logged.
100% pin-to-pin continuity and high-voltage testing on every unit, delivered with a formal, signed Certificate of Compliance in every box.
Skip the bureaucratic red tape. Our flat-rate model is perfectly tailored for university P-Cards and rapid startup budgets. FDA-audit-ready documentation from day one of prototyping, delivered fast.

At Cabelman, we believe that documentation is just as critical as the copper and silicone itself. Every lot we build features a detailed Certificate of Compliance and physical/electrical test metrics.
