Waterproof Connector FAQ: IP Ratings, Selection, MOQ & Custom Orders

Start with your application, voltage, current, pin count, cable outer diameter, installation method and operating environment . For outdoor and industrial applications, also consider temperature, vibration, moisture, UV exposure and corrosion.

For photovoltaic applications, see our solar connector selection guide . If you are comparing termination methods, you can also review screw-free vs screw-type waterproof connectors .

The first digit 6 means dust-tight protection. IP66 addresses powerful water jets, IP67 covers temporary immersion under defined conditions, and IP68 applies to immersion under conditions defined for the specific product.

The rating should always be checked together with the complete mated assembly, cable sealing method and the exact documented test conditions. For more detail, see our IP67 vs IP68 waterproof connector guide .

Confirm the finished cable outer diameter, conductor size, rated current, rated voltage, pin count, operating temperature and required IP protection .

The cable OD must fit the connector’s sealing range, while conductor size, current and voltage must match the contact and insulation system.

PVLinkTech currently offers high-current energy storage connectors from 70 A to 500 A, up to 1500 V DC, with IP67 options for applications including BESS cabinets, battery modules and power distribution.

Cable size, orientation, current rating, dimensions and installation requirements vary by model. See our energy storage connector range for the current product specifications.

PV4 products are designed for photovoltaic connection applications, but compatibility should be confirmed against the exact connector models, cable size, mating interface and certification requirements .

Do not assume two solar connectors can be mixed simply because their housings appear similar. Review our MC4 and PV4 solar connector page and send the existing connector details before specifying a mixed installation.

Yes. Selected standard PVLinkTech products are available from 1 piece for product evaluation, prototypes, replacement requirements and small trial orders.

Sample availability should be confirmed against the exact model before payment.

MOQ depends on product type, stock availability, customization, packaging and tooling .

Selected standard models can start from one piece, while fully customized manufacturing projects may have higher production minimums. Mixed-model orders can be reviewed according to the models and quantities required.

Yes. Depending on project feasibility, customization can include cable length, wire gauge, connector configuration, terminal type, housing, color, marking, labels, packaging and cable assemblies .

New tooling and certification requirements are evaluated separately. See our custom waterproof connector manufacturing capabilities .

Yes. Selected products can be supplied as pre-assembled cable assemblies based on your required cable type, wire gauge, cable length, connector, terminal, labeling and packaging .

Assembly requirements should be confirmed during quotation so the cable and connector specification can be reviewed as one system.

Depending on the connector model, available documents may include datasheets, dimensional drawings, electrical ratings, cable ranges, material information and product specifications .

Visit our waterproof connector datasheets or send the model number so we can confirm the files relevant to your project.

PVLinkTech holds management-system certifications including IATF 16949, ISO 9001, ISO 13485 and ISO 14001 .

Product certification and compliance coverage varies by exact model and target market. Available product-level documentation may include UL, cUL, TÜV, CE, UKCA, SAA, CQC, RoHS or other applicable documents.

See our certificates page and confirm the exact model before ordering.

Quality control includes specification review, material and component control, manufacturing-process control, assembly inspection and outgoing checks appropriate to the connector model.

For further information, see our quality control process .

For standard products already in stock, orders can typically be prepared within 3–5 business days.

Non-stock products, custom cable assemblies, new tooling, special packaging and large-volume orders require separate lead-time confirmation. Preparation time does not include international transit time.

Yes. PVLinkTech supplies overseas customers and can arrange shipment according to destination, shipment size, product weight, order value and required delivery time .

Freight, transit time, import requirements and applicable Incoterms are confirmed with the quotation or shipping arrangement.

PVLinkTech supports international payments in multiple currencies, including USD, EUR, GBP, CAD, AUD, JPY, HKD, SGD, NZD and CNY .

For regular production orders, bank transfer (T/T) is commonly used. For eligible samples and small-value orders, payment can also be supported through PayPal and credit card.

The available payment method, receiving currency, bank details and payment terms will be confirmed in the quotation or proforma invoice before payment.

If cartons or products arrive damaged, keep the original packaging, photographs, labels, product details and order information.

Our team will review the case against the confirmed order terms and provide the appropriate resolution. Product suitability should also be confirmed before installation or volume use.

Warranty terms are confirmed according to the product model, application and commercial terms stated in the quotation or order documents.

If an issue occurs, keep your order information, photographs and relevant product details so the case can be reviewed against the confirmed specification.
