Custom waterproof connector manufacturer PVLinkTech exists for projects a stock catalog cannot cover — a specific panel cutout, an IP69K washdown requirement, your own brand on the housing, or a yearly volume of a few hundred units. Standard parts either do not fit, or charge you for features you will never use.
We design and build the connection instead. Send a drawing, a sample, or a photo with your target ratings, and our engineers take it from there: feasibility review, DFM, prototype, certification route and production. The work runs on a 6,800 m² floor with 50+ automated lines and annual capacity above 10 million sets, so a custom project never stalls for lack of production space.

What Can We Customize
What does a custom waterproof connector manufacturer actually change? Here is the list we work with every week.
Below is what buyers ask us to change most often. If yours is not on the list, send it anyway. The list grows faster than this page updates.
| What we change | Examples we ship |
|---|---|
| Housing & tooling | New housing geometry, customer-owned molds, material changes (PA66 and other engineering plastics), metal parts. New molds typically run about 20 days. |
| Sealing & IP rating | IP67, IP68 and IP69K sealing designs: O-ring groove geometry, gasket material, overmolded joints. Sealing is engineered for your real test conditions, not just a datasheet number. |
| Contacts & terminals | Pin count, contact plating, terminal style (screw, screwless/push-in, or hybrid designs), matched to your conductor size. |
| Cable & overmold | Cable length and gauge, jacket material, shielding, pre-terminated leads, overmolded strain relief, custom cable assemblies. |
| Marking & brand | Housing color, laser marking, silk-screen logo, private-label packaging and labels. |
| Mounting | Thread size, panel cutout, flange, bracket and mounting-hole positions matched to your enclosure. |
| Certification & documentation | CE, RoHS, UL, TÜV, ETL and other marks are confirmed per model and target market. We do not claim a certificate a new design does not hold. |
Most custom jobs combine two or three rows above. Not sure if a change is possible? Send the drawing or a photo. The DFM review is free and usually answered within 1–3 days.
Standard Part or Custom Connector?
Choosing between a stock part and a custom waterproof connector manufacturer comes down to fit, volume and timing.
| Standard catalog part | Custom-built connector | |
|---|---|---|
| First samples | 2–4 business days from stock | 7–10 days typical; about 3 days for simple changes (color, cable, marking) |
| Tooling | None | ~20 days for a new mold; tooling quoted per project |
| MOQ | 1 piece | 500 pieces per model for production |
| Unit cost | Lowest at any volume | Higher until volume spreads the tooling |
| Best when | The catalog spec fits your design and deadline | Cutout, rating, cable, brand or volume is unique to your product |
Short version: a stock part fits your spec and your deadline → buy it (one-piece MOQ, 2–4 day ship). If any one thing is off (cutout, rating, cable, brand, or required volume), a custom build is usually the cheaper path than forcing a wrong part.
If you are not sure which side you are on, send the requirement anyway. We will tell you honestly if a standard line already covers it. We would rather sell you a $2 stock part today than push you into tooling you do not need. That is how a custom waterproof connector manufacturer keeps engineering time honest: it says no when no is the right answer.
How a Custom Connector Project Runs
The same four-step path runs every custom waterproof connector manufacturer project, from a one-off prototype to a 100,000-piece program.

Reply within 12 hours: requirement review
Send application details, drawings, samples or technical requirements. We check feasibility and confirm what we need to move forward. You do not need a finished drawing to start: a sample, a competitor part you already buy, or a marked-up photo is enough for the first review.
-
DFM & quotation
You receive engineering drawings, manufacturability recommendations (material, tolerances, mold design), pricing and lead time for approval.
-
Sample & validation
Samples for fit, function and reliability testing. IP tests on request. Simple modifications can return working prototypes in as fast as 3 days. Where a new injection mold is needed, tooling runs about 20 days before sampling.
-
Production & delivery
Approved product moves into controlled production: 100% inspection, custom packaging, on-time worldwide shipping. The same engineering team stays on the job from first sample to volume.
Engineering & Manufacturing Behind the Quote
What sits behind a custom build: engineering, tooling, testing and production capacity.
DFM from the first email
30+ R&D engineers review drawings for moldability, tolerance and material fit before you spend on tooling. We say early what will be expensive, and what can be simplified.
Prototypes you can actually test
Working samples in 7–10 days standard, about 3 days for simple changes. Samples are built to be installed, mated and IP-tested. Not shelf pieces.
Sealing is our core competence
IP67/IP68/IP69K is where we started. O-ring grooves, overmolding and gasket selection are engineered against your real washing, immersion and condensation conditions, supported by 20+ laboratory test instruments.
Small runs on a production floor
6,800 m², 50+ automated units, 10M+ sets annual capacity. A 100-piece pilot and a 500,000-piece program run on the same lines, under the same 100% inspection and quality control system (see certificates).
Tell Us What You Are Building

From a 100-Piece Run to a 120 MW Project
A real delivery with numbers we can stand behind.
We supplied connectors for a 120 MW PV plant in Indonesia with floating and ground-mounted sections, delivered through a Tier-1 EPC (name withheld under NDA). Eighteen months of field operation passed with no connector-related failures reported, and the installer cut crimping and assembly time by 25% against their previous supply.

Custom Connector FAQ
Straight answers to the questions buyers ask before sending a drawing.
Q When should I talk to a custom waterproof connector manufacturer instead of buying a stock connector?
A When the catalog part cannot match your panel cutout, IP rating, cable configuration, brand, or volume. A custom waterproof connector manufacturer is worth the call the moment you are forcing a wrong part into your design, or paying for ratings you will not use. Not sure? Send the requirement; if a standard line covers it, we will say so and point you to a one-piece order instead.
Q What is your minimum order quantity (MOQ)?
A Standard catalog items: 1 piece, shipped in 2–4 business days. Custom samples: 1 piece. Custom production: MOQ from 500 pieces per model. The 500-piece floor is deliberate — it keeps pilot runs and test-market launches affordable without tying you to container volumes.
Q How fast can I get a sample?
A Simple changes (color, cable length, marking, logo) return working samples in about 3 days. Standard custom samples run 7–10 days including drawing confirmation. If a new mold is required, tooling takes about 20 days before sampling. Samples are built to be installed, mated and tested — including IP tests on request.
Q Do you sign NDAs before we share drawings?
A Yes. Drawings, samples, DFM documents and pricing stay confidential, and we are used to working under NDA from the first exchange. Send the NDA or ask for ours before sharing anything sensitive.
Q Can you match a connector we already buy — second source or private label?
A Yes. Send the existing part or its specification sheet. We match the footprint, electrical ratings and mating interface, then apply your branding, color and packaging. This is a common way buyers open a second source without redesigning their enclosure.
Q Which certifications can a custom connector carry?
A Our production network holds CE, RoHS, UL, TÜV, ETL, CB, UKCA, NSW and CQC product certifications, plus ISO 9001/IATF 16949/ISO 13485 management system across its lines and sites. For a new custom design, certification coverage depends on the materials, ratings and target market. We confirm exactly what can be marked before you commit, and we do not claim a certificate a new design does not hold. Current scope: certificates page.
Q Do you handle low-volume production or trial runs?
A Yes. Production MOQ starts at 500 pieces per model, and most custom waterproof connector manufacturer relationships start at exactly that size. Because the factory runs 50+ automated lines with 10M+ sets of annual capacity, we can also scale the same design to hundreds of thousands when your market grows. The engineering contact stays the same at every volume.
Q What do you need from me to start?
A A drawing (DXF, STEP or PDF) is ideal but not required. A physical sample, a photo, or a list of target parameters — voltage and current, conductor size, IP rating, mounting hole, yearly volume — is enough to begin. You will get a first response within 12 hours.
