FAQ

WEIPU Connector offers a wide range of connectors, including circular connectors, CEE connectors, heavy-duty connectors, cable glands, customized products, and more. Our products cater to various applications and industries.

Circular connectors work by connecting two opposite connectors, creating a circuit. They can be cable-to-cable or cable-to-panel, and feature different locking mechanisms like threaded, bayonet, or push-push styles, providing secure connections and excellent environmental sealing.

Circular connectors are versatile and commonly used in various industries. Their round design allows for secure connections in applications ranging from aerospace equipment to scientific instruments and industrial machinery. With waterproof options available, they are particularly ideal for outdoor and rugged environments that require reliable, long-lasting connections.

Circular connectors offer a wide range of benefits, including multiple mating styles (thread, bayonet, push-pull) for different needs. They come in a variety of sizes, from compact connectors for lighter tasks to large, high-power connectors for demanding environments. Many circular connectors are designed for high durability, with features like IP68 waterproofing for use in tough conditions.

WEIPU offers a variety of connection types, including power, signal, and data connections. Additionally, we provide hybrid connections that combine power and signal connections in one connector. Our connectors support configurations from 1 to 61-pin options, with rated currents ranging from 3 to 150A to meet diverse application needs.

WEIPU offers a range of connector accessories, including cable assemblies, cable glands, adapters, junction boxes, crimp contact tools, etc.

While WEIPU connectors are designed to mate with each other within the same product family, compatibility with connectors from other brands cannot be guaranteed. If you are seeking a comparable alternative to our product range, please provide us with your specific requirements, and we will be glad to assist you in finding a suitable solution.

Yes, WEIPU connectors can be used for both Direct Current (DC) and Alternating Current (AC) applications. Our product specifications typically list ratings for AC. If you are planning to use the connector in a DC system, the voltage rating remains unchanged, but the current rating may experience a decrease of approximately 20-30%. It is important to consider this derating factor when selecting connectors for DC applications to ensure safe and reliable operation. For detailed guidance and to ensure compatibility with your specific requirements, please contact our team.

WEIPU Connector holds multiple certifications to ensure the highest quality standards and compliance with industry regulations. Our certifications include ISO 9001, IATF 16949:2016 for quality management systems, EN61984 / EN60309, RoHS compliance for environmental standards, and International Railway Industry Standard (IRIS). Additionally, certain series of our connectors are certified by UL and CSA. These certifications are a testament to our commitment to delivering reliable and compliant products. Our connectors undergo rigorous testing to meet and exceed industry requirements.

The Ingress Protection (IP) rating indicates the level of protection a connector or enclosure offers against solid particles (like dust) and liquids (like water). The first digit of the IP rating specifies protection against solids, while the second digit shows protection against liquids. WEIPU provides connectors with ratings up to IP68, ensuring robust protection for demanding environments, making them ideal for outdoor and industrial applications. 

Our connectors reach their specified IP waterproof protection level when a matching plug and socket are correctly mated, or when the connector is adequately covered with a cap designed for it. It’s important to ensure that these conditions are met to maintain the integrity of the IP rating in wet or dusty environments.

• If your application requires occasional exposure to water, IP67 connectors are sufficient.
• If your application involves constant water exposure or submersion, go with IP68.

Our IP68-rated connectors have undergone extensive testing to ensure their durability and protection against water ingress. In our own lab, we conducted a 1-week test under 10 meters of water to validate the IP68 rating. However, if your application has specific requirements, such as prolonged underwater usage or involves special composition/material, further tests should be arranged to ensure compatibility and suitability for your specific needs. We recommend discussing your requirements with our team to determine the best solution for your underwater application.

Our SP series and WK20 series offer IP68 protection.

Yes. Our high precision W series has IP68 and high hydrostatic pressure environments 30 bars. Please contact us for more information.

WEIPU connectors are available with various termination options, including solder, crimp, screw, and horizontal mount screw.

Our coupling options have thread, push-pull, bayonet, and push-lock. 

WEIPU connectors come with standard corrosion protection of 45 hours salt spray resistance. For customized needs, we offer additional options such as using alternative materials and increasing the thickness of the plating to enhance corrosion resistance.

Yes, we have angled-shaped connectors. Below is the core style we offer: 

The part numbers for WEIPU connectors are carefully designed to reflect detailed specifications. There are the elements usually included:

• Series Code: This initial part identifies the series to which the connector belongs, each with unique design features suitable for specific applications.
• Panel Hole Cutout Diameter: Numerical values following the series code specify the diameter of the panel hole cutout, helping to ensure the connector fits perfectly in its intended space.
• Contact Gender: Indicated by a letter—‘J’ & ‘P ’ for male contacts and ‘K’ & ‘S’ for female contacts—this part of the number helps you identify the type of connection.
• Number of Contacts: The numbers here represent the total amount of electrical contacts within the connector, affecting the connector’s capability and compatibility with various cable types.
• Termination Type: This part of the number, often starting with a dash, designates the type of termination, such as solder, screw, or crimp.
• Cable Outer Diameter Range: This aspect of the part number indicates the suitable cable diameter range the connector can accommodate, ensuring a secure and proper fit.
• Cap Inclusion: A final letter in the part number denotes cap options:
  • ‘C’: with a cap
  • ‘N’: without a cap
• Shell Structure and Cable Fix Type: Additional letters provide information about the shell structure and cable fix type, which include details about flange shapes, locking mechanisms, and cable accommodation specifics.

Below is an example of our WY series: 

WEIPU’s SP and SY series stand out due to their reliable performance and versatile applications. Despite their similar outlook, there are distinct differences that make each series unique.

Here is their main specification: 

WEIPU’s SF and SA series connectors share a similarity in their sleek design, often leading to inquiries about their specific differences.

Here is their main specification: 

The WS, WF, and WY series are all part of WEIPU’s comprehensive 3W family of connectors, offering a wide range of options for various applications.

The primary differences between the WS, WF, and WY series connectors are their coupling mechanisms and IP ratings:

The “Z” and “ZZ” designations in our 3W series part numbers both refer to the square flange socket connectors. “Z” is used for internal documentation purposes, while “ZZ” is the official designation used publicly. There is no difference between the connectors themselves.
