In today’s complex and fast-moving technology landscape, precision, performance, and reliability are non-negotiable. Whether you operate in aerospace, medical, defence, motorsport, or industrial automation, the cables that power your systems must meet exact requirements. That’s where custom cable assemblies from St. Cross Electronics come into their own.

With over 40 years of experience, advanced in-house design capabilities, and ISO and UL-certified facilities in the UK, we help businesses unlock the full potential of custom cable assemblies.

What Are Custom Cable Assemblies?

Custom cable assemblies are tailored interconnect solutions designed to meet the specific technical, mechanical, and environmental demands of your application. Unlike off-the-shelf options, custom assemblies are purpose-built – from the conductor type and shielding to connector configuration and jacket materials – ensuring seamless integration, durability, and long-term performance.

At St. Cross Electronics, we design and manufacture custom assemblies ranging from simple discreet wire sets to complex 1000+ circuit harnesses. Each is engineered to exact specifications and fully tested before delivery.

8 Reasons to Choose Custom Cable Assemblies from St. Cross Electronics

1. Precision Fit and Function

Custom assemblies are designed for your system – not adapted to it. This ensures a perfect electrical and mechanical fit, reducing installation issues and operational risks.

2. Flexibility by Design

Every project has unique constraints. Whether it’s tight spaces, unusual connectors, or harsh operating environments, we tailor every detail to your needs.

3. Enhanced Quality Control

All our assemblies are manufactured under ISO 9001 and UL standards with 100% electrical testing. You can depend on every loom to work first time, every time.

4. Optimised Performance

From signal integrity to EMI shielding and current capacity, custom assemblies are engineered to deliver consistent, high-level performance under real-world conditions.

5. Faster Installation

Pre-terminated and pre-labelled looms simplify on-site installation, reducing the time and cost associated with manual wiring.

6. Sustainable, Waste-Reduced Production

Tailored assemblies mean fewer excess materials, reduced storage requirements, and a lower environmental footprint.

7. Long-Term Cost Efficiency

While custom assemblies may have a higher upfront cost, they reduce downtime, maintenance, and integration issues over time – providing strong ROI.

8. Scalable to Your Needs

From one-off prototypes to production runs of 100,000+, we manufacture with the same care and consistency. From our facility in Southampton, Hampshire, in the UK, we scale without compromising quality.
