  • What is a custom cable assembly?

    A custom cable assembly is a wiring solution built to your exact specifications — length, connectors, shielding, materials, and configuration. It’s different from off-the-shelf cables because it’s designed for your specific application and performance needs.

  • Which types of cable assemblies can Epsems build?

    We can produce wiring harnesses, coaxial cables, ribbon cables, and overmolded cable assemblies. We also support customized connectors, shielding, and materials to match your project requirements.

  • How do you maintain quality and reliability in your custom cables?

    Every cable undergoes electrical, mechanical, and environmental testing. We also ensure compliance with standards like UL, RoHS, and industry-specific specs so your assemblies perform in real use.

  • Can I order a small batch or prototype first?

    Yes — we offer prototyping and small production runs before moving to large-scale manufacture. This helps you test the assembly in your application before full production.

  • How do I request a quote or place an order for custom cable assembly?

    Send us your specs (cable length, connector types, shielding, materials, application) via email or our contact form. We’ll then send back a detailed quote with pricing and lead time.
