FAQ:

What does PPS insert’s 260℃ max mean?

It refers to short-term high-temp resistance — handling transient heat in industrial equipment (not long-term continuous high temps) to avoid deformation.

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.

Can you provide on-site installation support for overseas projects?

Yes, we have a global technical team that can provide on-site services in major regions, with advance notice of 7-10 working days.

Which thread standard should I choose for my equipment?

It is recommended to confirm the equipment's origin and interface specification first. Metric thread is suitable for European equipment, PG thread for German standard motors/control cabinets, and NPT thread for American standard high-pressure equipment. Our technical team can also provide matching suggestions based on your equipment parameters.
