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, solar, marine, or industrial applications, also confirm UV exposure, vibration, temperature, moisture, and corrosion requirements. We can help match your requirements to a suitable product series before you order. For solar applications, see our solar connector selection guide.

Yes. PVLinkTech supports orders from 1 piece for product evaluation, prototyping, replacement needs, and small project requirements. This lets you check fit, installation, and performance before moving to a larger order.

For standard products that are in stock, bulk orders can typically be prepared for shipment within 3–5 business days. Lead time for non-stock models, custom cable assemblies, special packaging, new tooling, or large volumes will be confirmed based on the final specification and quantity. Shipment preparation time does not include transit time.

Depending on the product model, we can provide available datasheets, drawings, electrical ratings, cable-range information, material details, and product specifications. Please send the model number or your application requirements so we can confirm the documents relevant to your project.

Available compliance documents and test information vary by model and intended application. Please tell us the model, target market, and required standard so we can confirm the applicable documents before you place an order. Do not assume a document for one model applies to every product in a series.

Yes. Depending on project feasibility, customization may include cable length, wire gauge, connector configuration, terminal type, logo marking, shell color, labeling, packaging, and pre-assembled cable harnesses. We will confirm feasibility, MOQ, tooling requirements, and lead time before production.

We focus on specification confirmation, material selection, sealing design, assembly control, and inspection procedures appropriate to the product. For relevant models, available technical data and supporting documents can be reviewed before ordering, helping reduce the risk of mismatch between your application and the selected connector.

The first digit 6 means dust-tight protection. IP66 covers powerful water jets. IP67 covers temporary immersion under defined test conditions. IP68 covers immersion under manufacturer-defined test conditions. Always confirm the exact model, test condition, cable assembly method, and installation requirements before selecting a connector for long-term wet or underwater use.

Yes. Some products are supplied as field-installable components, and we can also provide pre-assembled cable assemblies based on your required cable type, length, terminal, labeling, and packaging. This can reduce installation work and help maintain consistent assembly quality.

PVLinkTech supports overseas customers and can provide shipment options based on product weight, volume, destination, order value, and required delivery time. Shipping cost, transit time, import duties, and local compliance requirements should be confirmed before order placement.

If cartons or products arrive damaged, please keep the packaging, photos, product details, and order information. Our team will review the case and provide a practical resolution according to the confirmed order terms. For product suitability, please verify the model and technical specification before installation or volume use.

Available payment methods and terms are confirmed in the quotation. International wire transfer is commonly used for production orders, while other options may be available for eligible sample orders. Terms can vary according to order value, customization level, and cooperation history.

MOQ depends on the connector model, stock availability, customization, packaging, and production requirements. Standard items may be available in small quantities, while custom connectors, cable assemblies, logo marking, or special packaging may require a higher MOQ. Send the models and quantities you need, and we will confirm whether mixed-model ordering is available for your project.

Select a waterproof cable connector only after confirming the cable outer diameter, conductor size, rated current, rated voltage, pin count, operating temperature, and required IP rating. The cable gland and sealing range must match the actual cable, while the contact and housing must suit the electrical load and installation environment. For solar PV applications, you can also review our MC4 and PV4 solar connectors.
