Prototype and low-volume cable assemblies
Justicia Marin coordinates prototype cable assemblies and low-volume runs for manufacturers and integrators, from your drawing, sketch, sample or specification. We select and coordinate the specialised manufacturer taking into account both the units you need now and the volume you expect later.
Prototype, pre-series and low-volume run
From the first prototype cable assemblies to a repeatable supply
These are not three names for the same thing. A prototype is the first units with which you check a configuration: lengths, connectors, terminals, identification or whatever you have defined for your application. A pre-series is a later small batch, used to check that the configuration repeats identically before a larger supply. And a low-volume run is a limited-volume regime that can be kept stable for years, not necessarily an intermediate step.
- Small quantities without requiring a series commitment
- The same specification that would apply to a larger supply
- Changes between versions are documented
- The approved configuration is kept between orders
A prototype can correspond to build-to-print cable assemblies, to custom wire harnesses or to custom electromechanical assemblies.
Stages and volume regimes
Prototype, pre-series and low-volume cable assemblies: what changes at each stage
Each answers a different question and allows a different level of requirement. Not all projects go through them in order.
Prototype cable assemblies
First units to check a configuration: that the lengths are right, that the connectors and terminals are the correct ones and that the assembly fits where it has to fit. You can check it on your own equipment before closing the definition.
Verification pre-series
A small batch with the configuration already closed. It is used to check that it repeats identically before ordering larger quantities. It is not an approval or a standards test: it is a repeatability check agreed with you.
Low-volume cable assemblies
Supply in limited and repeated quantities, usual for low-volume or niche equipment. It can be a stable regime: some projects stay here and do not need to move to larger quantities.
Approved configuration and repeat orders
We fix in writing the approved configuration and the revision it corresponds to, so that later orders do not depend on anyone’s memory and a change of revision is identifiable.
Starting data and criteria
What to define to request prototype and low-volume cable assemblies
The quote is prepared on the information available and sets out in writing the scope the selected manufacturer can take on. It is worth stating both the initial quantity and the volume you expect later: the same manufacturer does not always fit.
- Drawing, sketch or sample, even if the information is incomplete
- What you want to check with the first units
- Bill of materials or part numbers, if they exist
- Accepted equivalents when a part number is not available
- Lengths, connectors and terminations defined as far as you know
- Identification and protection, if the project requires them
- Agreed verification criteria
- Initial quantity and expected later volume
Decision points
Documentation, sample and continuity before the supply is repeated
These three milestones turn an initial need into a configuration that can be ordered again without reinterpretation.
Flexible starting point
We accept an incomplete drawing, a sketch or a sample. With prototypes the information is usually incomplete, and that is normal.
Validation on your equipment
You fit the units on the real product and confirm what to adjust before closing the definition.
Move to production
With the approved version, we prepare the series quote with price per quantity and supply lead time.
How we coordinate the supply
How we manage prototype and low-volume cable assemblies
The purpose is to reach the series with the definition closed and no surprises on lead time.
Starting documentation
We collect what you have: a drawing, sketch, sample or a description of what you need to check. With prototypes the information is usually incomplete and that does not block the quote.
Documented iteration
Every change between versions is recorded, so that the final version is identifiable and later orders refer to the same revision.
Checking and adjustment
You receive the units and check what you had defined. If anything has to be adjusted, it is corrected before the configuration is closed.
Low-volume run or later supply
With the approved configuration we prepare the quote for the quantities you need, with volume pricing and supply lead time.
Coordinated manufacturing
Manufacturing of prototype and low-volume cable assemblies with specialised manufacturers
The manufacturer that fits is not the same for a test unit as for a supply that repeats every month. The configuration, the components, the operations needed, the initial quantity, the volume expected later and the agreed checks all matter. We select and coordinate the one that corresponds in each case.
Do you need prototype and low-volume cable assemblies manufactured?
Justicia Marin coordinates the manufacture of prototype cable assemblies with specialised manufacturers, selected according to the configuration, quantities and requirements of the project. Production is carried out through our network; we centralise selection, coordination and supply so that you work with a single point of contact from the first unit.
What conditions the move from prototype to low-volume cable assemblies
Configuration — what is defined and what remains open
Components — part numbers, availability and accepted equivalents
Verification — what must be checked and against which criterion, where applicable
Quantity — initial units and volume expected later
Repeat orders — revision and configuration to be kept between orders
From approved configuration to recurring supply
Not all projects go through the three stages. Some documentation is mature enough to start directly as a low-volume run, and some projects stay there. When there is a prior sample, you approve it before committing to a quantity and from then on we keep the approved configuration between orders.
Justicia Marin does not manufacture in facilities of its own: we select, coordinate and verify the supply through specialised manufacturers. If the project requires a specific level of control when repeating, it is agreed as electrical verification and testing.

What this service actually covers
Prototypes are carried out by manufacturers in our network. At very small quantities the unit price is necessarily higher than in series, and some processes or tooling may not be available for a single unit. We tell you before accepting the order, together with the viable alternative, rather than accept a job that cannot be fulfilled.
Questions before the quote
Low-volume cable assemblies and prototypes: frequently asked questions
- What is the difference between a prototype and a low-volume run of cable assemblies?
- A prototype is the first pieces used to check a configuration: lengths, connectors, terminals and fit. A low-volume run is a limited, recurring supply of a configuration that is already fixed. A pre-series sits in between: a smaller batch to confirm that the approved configuration repeats identically before larger quantities are released.
- From how many pieces can I order cable assemblies?
- There is no minimum that always applies: it depends on the components, the operations and the manufacturer that fits the project. Single pieces are possible, but the unit price is then higher and some connectors or terminals are only sold per pack. This is stated in the quote before you decide, so that you can weigh the cost of a very small quantity.
- Can I start with an incomplete drawing or a sketch?
- Yes. With prototype cable assemblies the information is often still incomplete. A sketch, a sample or a description of what you want to check is enough to start. We tell you which data still has to be fixed, and every change between versions is documented until the definition is finished, so the final version is clearly identifiable.
- Who makes the prototypes and the low-volume runs?
- A specialised manufacturer that we choose based on configuration, components, quantity and the volume expected later. Sometimes a different manufacturer fits prototypes than the series; we discuss that in advance. Justicia Marin coordinates selection, samples and delivery; the physical production is carried out by the manufacturer.
- How do I know the series is identical to the approved prototype?
- The approved configuration is recorded in writing together with its revision: drawing, bill of materials, marking and agreed checks. The manufacturer works from that revision and every change is assessed and approved by you before the next batch. A pre-series can confirm that the repetition is right, with criteria such as IPC/WHMA-A-620.
- Is a pre-series always needed?
- No. A pre-series makes sense when the configuration is new or when the later volume is large. If the documentation is mature and the risk is small, a project can start directly as a low-volume run. We advise case by case and record the choice in the quote, together with the agreed checks.
- Are low-volume runs always more expensive than large series?
- The unit price usually falls with volume, because set-up costs and tooling are spread over more pieces. Yet many products stay in small runs for years, and then a stable, repeatable supply matters more than the lowest unit price. We show per quantity break what the volume means, so that you can choose on an informed basis.
