End-to-End Cable Assembly Solutions
Custom Cable Assemblies for Industry
JM Cableados has been producing custom cable assemblies and harnesses since 1987. As a family-owned, direct manufacturer, we handle everything in-house: precision wire cutting and stripping, terminal crimping, soldering, and connector assembly tailored to your specifications. From single-cable runs to complex multi-connector harnesses, we deliver exactly what you need—whether it’s a quick prototype run or full production, with no strict minimum order.
Who we are
Your Custom Harnesses, Built to Your Specs
We manage the entire process from start to finish: sourcing wire and insulation, precise cutting and stripping, crimping, soldering, and connector assembly—everything per your specifications. Every cable or harness we produce is built precisely to your drawings, references, and tolerances—no guesswork, no improvisation.
We serve diverse industries: medical devices, vending machines, power electronics, and access control systems. Beyond simple cables, we also produce complex assemblies—multi-connector harnesses, electrical subassemblies, and prewired bundles ready to install on your production line.
Family-owned since 1987 and based near Barcelona, we combine fast response, direct communication, and high flexibility. No middlemen, no bureaucracy—you deal directly with the people who build your cable assemblies.
