WEIPU WK Series Connector — Rugged Circular Industrial Connector

The WEIPU WK Series Connector is a rugged circular industrial connector family designed for reliable power, signal, and mixed-contact connections in harsh environments. WK connectors are commonly used in industrial automation, renewable energy (e.g., inverters and combiner boxes), rail transit, machine tools, robotics, outdoor lighting, and other mission-critical systems where vibration, moisture, or dust resistance are required. As part of WEIPU’s portfolio, the WK Series benefits from the company’s long-standing engineering and manufacturing expertise, making it suitable for both standard and customized, high-reliability deployments.

WK Series Connectors deliver ruggedness and practical design for industrial use: multiple contact configurations for power and signal, secure locking mechanisms, robust housings (plastic and metal options), and reliable sealing to protect against dust and water. WEIPU’s vertical R&D and production allow WK variants to meet demanding protection classes and specialized requirements; for customers needing extreme protection, WEIPU offers products across its portfolio with IP69K-level solutions and high-current options. For exact electrical and mechanical ratings (current, voltage, mating cycles, temperature), consult the WK Series datasheet or contact WEIPU so the correct variant can be matched to your specification.

Select a WK Series Connector by assessing: required contacts and pin layout (power vs. signal), current and voltage requirements, environmental protection level (IP rating), mechanical mounting style (panel mount, cable mount, inline), cable diameter and strain-relief needs, and regulatory/certification demands. Also consider lifecycle (mating cycles), vibration and shock characteristics, and whether an OEM/ODM customization is needed. If you’re unsure, provide WEIPU with your electrical specs, environmental conditions, and drawings—WEIPU offers rapid technical response and can recommend or prototype suitable WK variants within its one-stop solution process.

For reliable long-term operation: inspect connectors for damage and debris before mating; verify pin alignment and engage the locking mechanism fully; use the recommended torque values and correct cable glands/strain relief to preserve the seal; follow wire crimping or soldering guidelines provided by the datasheet; and protect connectors from chemical exposure outside their rated tolerance. For maintenance, perform periodic visual inspections, clean contacts with manufacturer-approved cleaners, and replace seals or worn parts as needed. For applications requiring sterilization or autoclaving, consult WEIPU about medical-grade solutions engineered to withstand high-temperature processes.

WEIPU is a manufacturer with nearly 30 years of connector expertise—founded in 1996 and a principal drafter of GB/T 11918-2014. The company operates an 80,000 m² facility with an annual capacity of 55 million units and offers over 70,000 specifications across circular, heavy-duty, and CEE ranges. WEIPU holds elite IRIS (rail transit) and IATF 16949 (automotive) certifications and provides independent R&D, vertical production, OEM/ODM services, and fast prototyping (typically 7–15 days).
