Dupont Cable Assembly
Custom Dupont-style cable assemblies for prototyping, embedded systems, test fixtures, and low-current production interconnects. We build single jumpers, bundled harnesses, and custom pinout breakout cables with 100% electrical verification.
Dupont Cable Formats
We manufacture jumper-wire style assemblies from single leads to organized multi-position harness sets.
Assembly Capabilities
Small-pitch jumper assemblies still need disciplined crimping, pinout control, and inspection to avoid field wiring issues.
Precision Crimping
Controlled crimp height and pull-force verification for small open-barrel terminals
Color-Coded Harness Sets
Consistent wire colors and labels for faster installation and debugging
Prototype to Production
Single engineering samples through repeatable batch manufacturing
Pinout Control
Straight-through, crossover, mirrored, and custom breakout pin mapping
Strain Relief Options
Heat shrink, lacing, and bundling for internal equipment cable management
100% Electrical Test
Continuity and pinout verification before shipment
Better Than Off-the-Shelf Jumper Packs
Off-the-shelf jumper wires are useful for lab work, but production builds often need exact lengths, stable color sequencing, and known pin mapping. We manufacture Dupont-style harnesses to your drawing so installers do not have to repin generic jumpers on the bench.
- Exact circuit count and custom lengths
- Female, male, and mixed-end combinations
- Straight, crossed, and branched pinouts
- Bundled sets for modules and test fixtures
- Wire color planning for easier service work
- Heat shrink and labeling when required
- Prototype through volume production support
- 100% continuity and pinout verification
Typical Applications
Embedded Electronics
MCU boards, dev kits, and sensor modules
Test Fixtures
Bench validation, functional test, and debug adapters
Internal Equipment Wiring
Low-current board interconnects inside enclosures
Prototype Harnesses
Fast-turn samples before locking the final connector family
Key Specifications
These are the most common variables we confirm before tooling and production release.
Custom Dupont Cable Assembly for Board-Level and Fixture Wiring
As a specialized Dupont cable assembly manufacturer, we build 2.54mm jumper-wire style harnesses for embedded electronics, module interconnects, and low-current internal wiring. In the market, "Dupont cable" is usually shorthand for the jumper format that mates with standard 0.1 inch headers commonly used on prototyping boards and compact electronic modules. The underlying connection style is closely related to the header-and-jumper ecosystem described in the jumper wire and pin header references.
We usually recommend custom-built jumper harnesses when your team has moved beyond one-off breadboard work and needs controlled lengths, stable wire colors, and repeatable pin mapping. That is common in fixtures, small control boxes, internal sensor modules, and service adapters where a generic retail jumper pack creates too much variation. Our broader custom cable assembly workflow lets us match each cable to your wiring list instead of forcing the design to fit a stocked jumper assortment.
Terminal quality matters even on low-current interconnects. Small open-barrel crimps still require proper conductor insertion, insulation support, and retention checks. That is why we combine validated crimp settings with our crimping capability and final continuity testing to prevent swapped positions, intermittent terminals, and mislabeled harness sets from reaching your line.
Dupont-style connectors work well for accessible, low-current, indoor applications, but they are not always the right long-term interface. If your design needs stronger retention, smaller pitch, sealing, or higher current, we often guide customers toward JST, Molex, or TE Connectivity systems. For flat multi-position routing, an IDC cable assembly may be a better production choice.
We support quick-turn prototypes, engineering sample packs, and repeat production lots with no minimum order constraint. If you send a pin list, cable drawing, or sample assembly, we can convert it into a controlled manufacturing build with labeled revisions, documented pinout, and the exact cable lengths your technicians need.

Dupont Cable FAQ
In practice, buyers usually mean 2.54mm jumper-wire style cable assemblies that mate with standard 0.1 inch pin headers. The term is used broadly in the electronics market, so we confirm housing style, gender, pin count, wire gauge, and pinout before production.
Yes. We build straight-through, crossed, mirrored, and branched harnesses. We verify every assembly against your pin map, wire list, or sample so the finished cable matches your board-to-board or module-to-module routing exactly.
They can be suitable for low-current, internal, and serviceable connections when retention force and environment are appropriate. For higher vibration, sealing, or current requirements, we usually recommend locking crimp systems such as JST, Molex, TE Connectivity, or sealed automotive connectors.
The fastest quote includes housing gender, circuit count, wire gauge, length, color sequence, pinout, quantity, and whether you need bundled sets, labels, or mating headers. A drawing, spreadsheet pin list, or sample cable all work well.
Yes. We perform 100% continuity and pinout verification on production lots. For programs with tighter requirements, we can also document pull-force checks, first-article inspection, and custom functional tests.
