Question you may concern
Can the SF Series maintain IP67 protection performance after customization?
Yes. All customization services for the SF Series (such as structural adjustment and material replacement) will undergo strict waterproof and dustproof performance testing. We will ensure that the modified product still meets the IP67 protection standard, while maintaining its original insulation performance and coupling reliability. You can contact our sales team to put forward specific customization requirements.
How to choose the housing model for Weipu heavy-duty connectors?
Match the housing model with the heavy-duty connector model (e.g., choose 16A housing for 16A model connector) to ensure installation compatibility.
What is the function of the 3+PE contact configuration?
The 3+PE contact configuration includes 3 contacts for transmitting power or signals and 1 PE (protective earth) contact. The PE contact is connected to the equipment shell and the earth, forming a protective earth loop. When the equipment has electrical leakage, the leakage current can be quickly discharged to the earth through the PE contact, avoiding electric shock hazards to operators and protecting the safety of equipment and personnel.
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).
