Features​

  • High Quality Materials: The WS28 connector is crafted with a zinc alloy shell, which offers excellent corrosion resistance and high strength. This ensures long term durability even in harsh industrial environments. The insert is made of PPS (Polyphenylene Sulfide) material, which can withstand high temperatures up to 260 °C, providing reliable insulation.​
  • Reliable Electrical Performance: The contact material is brass with gold - plating. This combination not only reduces contact resistance but also enhances conductivity, ensuring stable power and signal transmission. For example, the 2 pin version has a contact diameter of φ3.5 x 2, a rated current of 50 A, and a rated voltage (AC.V.) of 500V, with a low contact resistance of 0.5 mΩ.​
  • Waterproof Design: With a protection level of IP65, the WS28 connector can effectively prevent water and dust ingress. Whether it is used in outdoor construction sites or humid industrial workshops, it can maintain normal operation without being affected by the external environment.​
  • Threaded Coupling: The threaded coupling design makes the connection more secure. It is easy to install and remove, and can withstand a certain degree of vibration and pulling force, reducing the risk of accidental disconnection.​
  • Versatile Termination: It supports solder termination, which provides a strong and reliable electrical connection. This termination method is suitable for a variety of wire and cable types, making it convenient for different application scenarios.​

Product Series Details​

The WEIPU WS28 series is part of the ZBLZGP comprehensive circular connector product line. The series offers a wide range of pin configurations, from 2 pin to 26 pin options. This allows for flexible application in different systems, whether it is for power transmission in industrial machinery or signal connection in control systems. The series is designed to meet the needs of various industries, including but not limited to industrial automation, machinery manufacturing, and transportation. It is also compliant with relevant international standards, ensuring its quality and compatibility in the global market.​
