Custom JST Cable Assembly
We cut, strip, crimp and assemble custom JST cables across PH, XH, GH, SH, ZH, EH and VH series for modules, battery packs, sensors and PCB interconnects. no minimum order quantity — prototype reviews start at one piece.
A dedicated page for buyers sourcing custom JST cable assemblies
JST is the default connector family for consumer electronics, LED modules, small battery packs, and embedded boards. If you already know you need a JST cable and just need it built correctly to your specification, this is the page for it. Our broader cable assembly service covers the full connector range, while this page stays focused on manufacturable custom JST cables.
We are an assembler, not a parts distributor. You send the series, pin-out, wire, colour, and length, and we cut, strip, crimp, and assemble the finished lead. Related fine-pitch families we also build include Molex and DuPont cable assemblies.
Best Fit
LED modules, battery packs, sensors, IoT boards, and PCB interconnects that specify a JST series.
Not a Fit
Buying loose JST connectors. We only assemble finished custom cables, we do not sell bare parts.
JST Connector Series We Assemble
We terminate the full range of common JST wire-to-board and wire-to-wire families. Match your board callout, or tell us the current and space and we will confirm a suitable series.
Current values are typical guidance and depend on wire gauge, contact plating, and the number of loaded circuits. We confirm the working rating against your actual build at quote.
What Our Custom JST Assembly Service Includes
The assembly scope covers cutting and stripping, crimping, housing insertion and the electrical or mechanical checks stated on the released drawing.
Custom-Only, BOM Driven
We build custom JST cable assemblies to your drawing or BOM. Send the series, pin-out, wire gauge, colour code, and length, and we assemble the finished cable. We do not sell loose connectors.
Cut, Strip, Crimp, Assemble
Every JST assembly runs through the same controlled flow: precision cut-to-length, controlled strip, JST-applicator crimping, housing insertion, and inspection before it ships.
Fine-Pitch Capability
We terminate down to 1.0mm pitch (SH) for dense PCB interconnects and small modules, using JST-specified applicators to hold crimp height and pull force.
Correct Crimp Discipline
JST reliability lives in the crimp. We follow JST crimp-height and pull-force targets so terminals seat fully and lock into the housing without back-out.
Wire-to-Board and Wire-to-Wire
We build both board-mount interconnects and wire-to-wire jumper leads, including mixed-end assemblies where one side is JST and the other is a different connector or a stripped/tinned lead.
Drawing-Defined Electrical Testing
Continuity, polarity, resistance and pull checks are assigned in the traveler when the released specification calls for them.
Custom JST cables for LED modules
LED modules and light bars almost always interconnect with JST. We build custom JST cables for LED modules to the exact lead length, colour code, and polarity each fixture needs, so your line does not have to trim or re-pin in the field. GH and PH series cover most module and strip work, with VH available where a driver or channel carries more current.
Because we assemble to your BOM, we keep keying and pin order consistent across every unit, which is what stops reversed LED channels and mis-mated drivers on the assembly line. See our LED lighting industry page for the broader program context.
- GH (1.25mm) and PH (2.0mm) leads for LED strip-to-strip and strip-to-driver jumpers
- Board-mount JST headers for LED modules, panels, and linear light bars
- Colour-coded and keyed housings so polarity and channel order stay correct on the line
- Cut-to-length runs so each fixture gets the exact lead it needs without field trimming
- Optional heat-shrink and strain relief at the exit for modules that flex during install
Specifications tied to real JST manufacturing scope
Scope and Limits
Included scope
- Custom JST cable assemblies built to your drawing or BOM
- Wire-to-board, wire-to-wire, and mixed-end JST leads
- Prototype through production quantities under released build instructions
Out of scope
- Selling loose JST connectors, housings, or contacts on their own
- PCB fabrication or board-level assembly beyond the cable interface
- Programs that actually need a different connector family because the pitch or current is wrong for JST
Every crimp is built with our crimping and cutting and stripping capability, then verified before release.
How Custom JST Cables Move Through Production
This workflow is built for teams that need a quoted JST lead to become a repeatable manufactured part number.
Specification Review
We confirm the JST series, housing pin count, pin-out, wire gauge and colour, cable length, and whether the assembly is wire-to-board, wire-to-wire, or mixed-end.
Material Match
Contacts, housings, and wire are matched to the callout. If a series or pitch is not right for the current or space, we flag it before building rather than after.
Cut, Strip, Crimp
Wire is cut to length and stripped to a controlled window, then crimped on JST applicators to the specified crimp height and pull force.
First-Article Build
Sample assemblies verify fit, latch engagement, keying, and pin-out against the drawing before the definition is released to production.
Electrical Verification
Assemblies move through continuity testing plus any polarity or pull-force checks that belong in the released manufacturing traveler.
Repeat Supply
Once approved, the same controlled JST definition can be reordered without shifting materials or crimp targets between batches.
Custom JST cable assembly for electronics, LED, and battery programs
A custom JST cable assembly is usually specified because a board or module already uses a JST footprint and the buyer needs a lead built exactly to that interface. That is the job this page is built to quote and produce. We are a cable assembler, not a connector shop: we take your JST series, pin-out, wire gauge, colour code, and length, then cut, strip, crimp, and assemble the finished cable. Buyers looking to compare families first can start from our broader cable assembly overview.
The technical context is straightforward but important. The JST connector family spans many pitches and current classes, from 1.0mm SH signal leads up to 3.96mm VH power leads. Choosing the right series is only half the work. The reliability of the finished JST cable assemblies depends on crimp height, pull force, and full latch engagement in the housing, which is why we build every termination with JST-specified applicators and verify it before release.
Demand for custom JST cables clusters around a few real programs. LED modules and light bars use GH and PH leads for strip-to-strip and strip-to-driver connections, and custom JST cables for LED modules are one of our most common builds. Battery packs for RC vehicles, drones, and cordless tools use XH and SM leads; cordless programs that also need trigger, motor, and charger leads in one routed harness can extend into our power tool wire harness build. Sensors, IoT boards, and embedded modules use the fine-pitch SH, GH, and ZH families for dense PCB interconnects.
Because we build finished cables rather than sell parts, a custom JST assembly can also be mixed-end. We build JST-to-JST, JST-to-board header, JST-to-stripped end, and JST-to-other-connector leads, including transitions to Molex and DuPont when a system needs a fine-pitch JST side and a different downstream interface.
To get a fast, accurate quote, send a drawing or a completed RFQ template with the series, pin-out, wire, colour, length, and quantity. With no minimum order quantity — prototype reviews start at one piece, 48 hours prototyping, and drawing-defined electrical testing, we support JST programs from a first article through repeat production.
Custom JST Cable FAQ
We are a cable assembler, not a connector distributor. We build finished custom JST cable assemblies to your BOM: we cut, strip, crimp, and assemble the cable using JST housings and contacts. We do not sell loose connectors or bare housings on their own.
Yes. Custom JST cables for LED modules are one of our most common builds. We typically use GH (1.25mm) and PH (2.0mm) series for strip-to-strip, strip-to-driver, and module interconnects, with colour coding and keyed housings so polarity stays correct during assembly. Send the module pin-out, wire gauge, and lead lengths and we build the finished leads.
No. We support no-MOQ ordering, so you can start with a small prototype or first-article lot and move into repeat production using the same approved JST definition. This suits early hardware programs that need a handful of validated leads before committing to volume.
We regularly terminate SH (1.0mm), GH (1.25mm), ZH (1.5mm), PH (2.0mm), EH (2.5mm), XH (2.5mm), and VH (3.96mm), along with SM, PA, and other common wire-to-board and wire-to-wire families. If your board already specifies a series, we match it; if you are unsure, tell us the current, pitch, and space and we will confirm a suitable family.
A fully defined JST assembly can use the 48 hours prototype path once the pin-out, wire and length are confirmed. Actual timing depends on housing and contact availability and any custom test requirements, which are confirmed at quote.
The fastest way is a simple drawing or a filled-in RFQ that lists the JST series and pin count, the pin-to-pin wiring (pin-out), wire gauge and colour, overall length, and quantity. A photo of the existing cable or the mating board also helps. We turn that into a first article for your approval before releasing production.
Yes. Mixed-end JST cable assemblies are common. We build JST-to-JST, JST-to-board header, JST-to-stripped/tinned end, and JST-to-other-connector leads, such as JST-to-Molex or JST-to-DuPont transitions, when the system needs a fine-pitch JST side and a different downstream interface.
