WEIPU S-Series IP68 Industrial Cable Connector

Discover WEIPU's S-Series IP68 industrial cable connector lineup: a purpose-built collection of waterproof, circular connectors optimized for harsh environments and mission-critical systems. The S-Series IP68 industrial cable connector offers dependable sealing, consistent electrical performance, and easy installation so operations teams and OEM designers can focus on uptime and scalability rather than field failures.

Explore our High Quality S-Series collection

Every S-Series connector is engineered to solve real-world connectivity challenges where moisture, dust, vibration and repeated mating cycles threaten system reliability. Rather than presenting a single product, the collection offers modular designs that adapt to cable-to-cable, cable-to-panel and sensor interface needs. This flexibility reduces SKUs, speeds assembly, and simplifies maintenance across fleets of machines and distributed assets.

IP68-rated sealing for long-term immersion protection and dust exclusion.
Circular form factors that balance compact size with straightforward alignment and locking.
Multiple contact arrangements for signal, power and mixed-signal use cases.
Panel-mount and in-line variants for versatile integration into machines, enclosures and junction boxes.

Why WEIPU: trusted design, industrial scale, and compliance

Founded in 1996, WEIPU has grown into a global leader in industrial connectors and is a principal drafter of the GB/T 11918-2014 national standard. Our nearly 30 years of focused R&D and vertically integrated manufacturing ensure that every S-Series connector reflects practical experience from 30,000+ customers across 130 countries. In 2025 we expanded manufacturing capacity to an 80,000 m² facility supporting an annual output of 55 million units—allowing rapid fulfillment for both standard orders and customized programs.

WEIPU's credentials support mission-critical adoption: IRIS certification for rail transit and IATF 16949 for automotive quality systems. Our technology portfolio also includes IP69K protection, high-current solutions up to 800A in other product families, and specialized medical-grade connectors that withstand 134°C autoclaving. When you specify S-Series connectors, you gain a partner with proven test protocols, stringent QC, and a 24-hour responsive support model for OEM/ODM projects and prototype delivery in 7–15 days.

Real-world benefits and selection guidance

Choosing the right connector is as much about lifecycle performance as it is about upfront cost. The S-Series focuses on reducing total cost of ownership by minimizing field interventions and simplifying repairs. Key selection factors include contact count, current rating, cable gland sizing, and the environmental class required for the application. Consider these practical points when evaluating options:

Match IP rating and ingress protection to the site conditions: IP68 ensures continuous immersion resistance; if high‑pressure washdowns are expected, consider connectors or assemblies tested to IP69K.
Balance contact density and conductor gauge for thermal performance: higher currents need larger contacts and more robust housings.
Choose locking mechanisms and panel interfaces that reduce accidental disconnection in vibration-prone installations.
Leverage WEIPU's customization services when unique cable entries, color-coding, or labeling will reduce installation error or speed up field service.

Installation and maintenance are intentionally straightforward: clear mating guides, accessible sealing interfaces, and replaceable gaskets help technicians perform service quickly and consistently. For engineering teams, WEIPU provides technical drawings, test reports, and application notes to validate choices during design reviews.

FAQ

Are S-Series IP68 connectors suitable for outdoor and marine applications?

Yes. S-Series connectors rated IP68 are designed to resist continuous immersion and ingress of dust, making them well suited for outdoor installations and light marine exposure. For environments with high-pressure washdowns or steam cleaning, evaluate IP69K-rated variants or complementary sealing solutions to ensure long-term protection.

How do I choose the correct S-Series connector size and contact configuration?

Select size and contact layout based on conductor gauge, current requirements and signal density. Start by defining the highest current per contact, then choose a contact arrangement that accommodates those conductor sizes without overheating. Consider mechanical mounting (panel or in-line), cable gland diameter, and whether mixed signal/power arrangements are needed—WEIPU can provide drawings and application guidance to match your exact specifications.

Can S-Series connectors withstand industrial chemicals, temperature swings, and vibration?

S-Series housings and seals are formulated for industrial durability: they resist common oils, solvents and moderate chemical exposure, operate across wide temperature ranges, and include locking features that withstand vibration. For specialized chemical exposures or extreme temperatures, WEIPU recommends material verification and can supply alternative elastomers or plating options tailored to the environment.

What is the difference between IP68 and IP69K, and when do I need IP69K?

IP68 certifies protection against dust ingress and prolonged immersion; IP69K adds high-temperature, high-pressure washdown resistance, commonly required in food processing and heavy washdown applications. Choose IP69K when equipment is subject to steam cleaning, high-pressure sanitization, or stringent hygiene protocols; otherwise, IP68 is sufficient for submerged and dusty environments.

Does WEIPU offer customization and what are typical lead times for prototypes and production?

Yes—WEIPU provides OEM/ODM services and rapid prototyping. With vertically integrated manufacturing and dedicated R&D, prototype turnaround is typically 7–15 days for common modifications. Production lead times vary by volume and complexity; our expanded 80,000 m² facility supports fast scaling. Contact salse01@weipu-group.com or +86-020-80501102 for a tailored quote and timeline.
