FAQs about Circular Electrical Connectors
Weipu SY Series Industrial Connector High Reliability Electrical Plug Socket for Automation Equipment
What is the difference between the tin-plated and gold-plated contacts of the SY series? How to choose?
Tin-plated contacts have good conductivity and cost-effectiveness, suitable for general industrial environments; gold-plated contacts have better corrosion resistance and lower contact resistance, suitable for harsh environments with high humidity, salt spray or frequent mating. It is recommended to choose according to the actual working conditions and budget.
What is the protection level of the Weipu SY series connectors, and what working environments are they suitable for?
The SY series connectors have an IP68 protection level. The first digit "6" means complete protection against dust intrusion, and the second digit "8" means long-term immersion in water at a specified pressure without water ingress. They are suitable for harsh environments such as outdoor rainy days, underwater short-term work, dusty industrial workshops, and oily and high-vibration construction sites.
Can the SY series connectors be used for signal transmission and power supply at the same time?
Yes. The SY series supports simultaneous power supply and signal transmission under the premise of matching the rated parameters (voltage/current). It is recommended to reasonably arrange the pin layout during customization to avoid mutual interference between power and signal lines.
Are the SY series connectors compatible with the SP series of Weipu?
The interface dimensions and locking mechanisms of the SY series and SP series are different, and they cannot be directly mated. If you need to replace or match, it is recommended to use the same series of products or consult the Weipu technical team for solution design.
