Cable Assembly Manufacturers
Last updated: January 2026
This directory lists 115 cable assembly manufacturers across the United States, from specialized boutique shops to full-service EMS providers.
Buyers in this category are typically solving critical challenges such as ensuring signal integrity over long runs, achieving superior EMI/RFI shielding for sensitive electronics, or building assemblies capable of extreme environmental sealing against moisture and dust. The correct selection of wire gauge, conductor material, and connector type is paramount, often demanding close collaboration with a manufacturer experienced in Design for Manufacturability (DFM) for cable and wire harness assemblies.
Supplier types in this space range widely: from nimble, specialized shops focusing on low-volume, high-mix custom assemblies, often utilizing hand assembly and intricate potting or overmolding for medical or aerospace prototypes; to large, highly automated facilities equipped with high-speed cut-strip-crimp machines, optimized for high-volume production of more standardized assemblies. Some manufacturers specialize in specific industry certifications like AS9100 for aerospace or IATF 16949 for automotive, while others provide general industrial solutions with broad UL/CSA compliance.
To engage effectively, buyers must come prepared with a comprehensive Bill of Materials (BOM) specifying manufacturer part numbers for all components (wires, connectors, terminals, heat shrink, labels), along with clear 2D or 3D assembly drawings detailing dimensions, routing, and critical tolerances. It’s also crucial to specify the required IPC/WHMA-A-620 workmanship class (e.g., Class 2 for general industrial, Class 3 for critical applications) and clearly outline all necessary testing protocols, such as continuity, Hi-Pot, and pull-force testing. Suppliers will expect clarity on your application, expected annual volumes, and any specific regulatory compliance needs like RoHS/REACH or ITAR registration.

How to Choose a Company
- Verify the manufacturer's adherence to relevant workmanship standards; for medical or aerospace applications, require certification to IPC/WHMA-A-620 Class 3, and request evidence of their internal auditing, operator training records, and pull-force testing procedures for crimping.
- Assess their in-house testing capabilities: confirm they can perform 100% continuity testing for every circuit, Hi-Pot (dielectric withstand) testing to your specified voltage, and insulation resistance testing for shielded cables. For high-frequency data cables, inquire about specialized attenuation and crosstalk testing.
- Evaluate their expertise and tooling for specialized processes: if your design incorporates custom overmolding for strain relief, environmental sealing, or aesthetic finishing, ensure they have proven experience with tooling design and material selection for your required polymer, or access to reliable partners for these capabilities.
- Investigate their component procurement strategy: a common gotcha is a manufacturer relying on single-source or long-lead-time components without offering alternatives. Ask about their supply chain resilience, component lifecycle management, and how they handle potential obsolescence for critical connectors and wire types on your Bill of Materials (BOM).
- Red Flag: Be highly skeptical of any manufacturer who provides a quote without thoroughly reviewing your detailed assembly drawings, Bill of Materials, and without asking about your required IPC/WHMA-A-620 workmanship class or specific testing requirements. This often indicates a lack of due diligence, a potential for significant quality issues, or an inability to accurately price the true scope of work.

Frequently Asked Questions
What's the difference between a cable assembly and a wire harness?
While often used interchangeably, a 'wire harness' typically refers to an organized bundle of wires, often with individual wires cut to length, sometimes terminated on one or both ends, and secured together, usually for routing power or signals within a static environment. A 'cable assembly,' however, often implies a more complex, finished product, frequently incorporating multiple wire types (e.g., shielded, coaxial), specific connectors on both ends, and often includes features like overmolding, potting, specialized sleeving, or strain relief designed for dynamic applications or external exposure. Cable assemblies are usually designed for plug-and-play functionality in a specific system.
What documentation do cable assembly manufacturers need for quoting?
For an accurate quote, manufacturers require a comprehensive package. This includes a detailed Bill of Materials (BOM) listing all components (wires, connectors, terminals, heat shrink, labels) with manufacturer part numbers (MPNs), descriptions, and quantities. You'll also need clear assembly drawings (2D or 3D) showing dimensions, wire routing, stripping lengths, crimp specifications, pin-outs, color coding, and any critical tolerances. Additionally, specify the required IPC/WHMA-A-620 workmanship class, testing requirements (e.g., continuity, Hi-Pot, pull force), target volumes, and any regulatory compliance needs (e.g., RoHS, UL, AS9100).
Why is Hi-Pot testing crucial for cable assemblies?
Hi-Pot (high potential) testing, also known as dielectric withstand testing, is critical for verifying the insulation integrity of a cable assembly. It applies a high voltage between conductors, or between conductors and shield/ground, to detect any breaks, pinholes, or weaknesses in the insulation that could lead to electrical shorts, arcing, or catastrophic failure during operation. For safety-critical or high-voltage applications, 100% Hi-Pot testing is non-negotiable, ensuring the assembly can safely withstand expected electrical stresses and preventing dangerous electrical shocks or equipment damage.
Should I specify components or let the manufacturer source them for my cable assembly?
This depends on your expertise, design control, and cost strategy. Specifying exact components (connector series, wire gauge, insulation type, brand and MPN for terminals) gives you maximum control over the design and ensures consistency if you switch manufacturers. However, it places the burden of component procurement on you or requires the manufacturer to follow your exact BOM, potentially limiting their ability to leverage their supply chain relationships or offer cost-saving alternatives. Letting the manufacturer source components (turnkey solution) can simplify your process and potentially lower costs if they have favorable pricing, but it requires trust in their sourcing capabilities and may lead to component substitutions if not properly managed through an Approved Vendor List (AVL) and clear change control.
