Cable harness assembly is at the core of what we do at RTR Electronics. We specialise in custom cable harness assembly for clients who need reliable, high-quality wiring, building harnesses for automotive, aerospace, medical, telecommunications and industrial applications from our facility in Limerick, Ireland.
Do you build harnesses to a customer drawing or design from scratch?
Both. We build to your drawings and can also design a harness from a wiring schematic or sample.
Can you handle small batch and prototype harnesses?
Yes. We support prototype and low-to-medium volume cable harness assembly runs.
Do you test every harness before shipping?
Yes. Each harness is continuity tested, with hipot testing available on request, and results are documented.
Which connector families do you work with?
We work with most common connector families including Molex, JST, TE Connectivity and circular connectors, selected to suit your application.
For background on wiring standards, see the Wikipedia cable harness article.
Whether you need a one-off prototype or an ongoing production run, our cable harness assembly team works closely with your engineers to get the build right the first time. We review your drawings, advise on connector and wire selection, and document every step so each harness is repeatable and fully traceable.

We supply cable harness assembly to several sectors. For medical device customers we build harnesses with the documentation and traceability that regulated products demand. For automotive and transport clients we produce robust looms that withstand vibration, heat and long service life. For industrial and control systems we assemble power and signal harnesses for panels, machinery and instrumentation. Our team also supports telecommunications and IoT hardware where consistent, repeatable wiring is critical. Because design, assembly and testing all happen under one roof in Limerick, we keep lead times short and quality high across every cable harness assembly project we take on.
