Explore Our High Quality Waterproof Connector Range

Circular and Heavy-Duty Connectors

Our circular connectors provide compact, rugged sealing for sensors, motors, and field devices. Heavy-duty variants deliver enhanced mechanical strength and vibration resistance for construction, rail, and renewable energy systems. Available materials and plating options meet diverse environmental and electrical requirements.

High-Current and Specialized Solutions

For power-intensive applications, WEIPU offers high-current designs—supporting up to 800A—engineered for safe, low-loss connections. Medical-grade products withstand autoclaving to 134°C for sterilization, while IP69K-rated models resist high-temperature, high-pressure washdowns required in food processing and outdoor equipment.

FAQ:

What does the IP67 rating of the WF Series connectors mean?

The IP67 rating indicates two key protection levels: "6" means complete protection against dust ingress (no dust can enter the connector), and "7" means protection against temporary immersion in water (it can be immersed in water up to 1 meter deep for 30 minutes without damaging the internal components or affecting performance).

What does "omit" mean in the cable outer diameter range of the SF Series models?

"Omit" indicates that the corresponding cable outer diameter type of the model is not provided. Customers can select the available type (Type I or Type II) according to their actual cable diameter needs. For example, the SF6 model only provides Type I (2-3mm) and does not provide Type II (3-4mm).

Can the ST Series be used in high-voltage scenarios?

Yes. The ST Series has an insulation resistance of up to 2000MΩ, which has excellent electrical insulation performance and can effectively isolate electrical signals. It is suitable for high-voltage scenarios within the safe voltage range. It should be noted that the specific use needs to comply with relevant industrial electrical standards and specifications.

What's the difference between plastic and metal housings of Weipu heavy-duty series?

Plastic housing: Lightweight, corrosion-resistant, cost-effective, suitable for mild low-vibration scenarios; Metal housing: High mechanical strength, strong vibration resistance, suitable for high-load high-vibration industrial equipment.

Can WS Series Connectors be used in outdoor low-temperature environments?

Yes. With a temperature adaptation range of -40°C~+85°C, they can operate stably in extreme low-temperature outdoor environments, making them suitable for outdoor industrial facilities in cold regions.
