Do connectors for hot air balloons require a high protection rating?

Q: Do connectors for hot air balloons require a high protection rating?

A: An ultra-high protection rating is unnecessary; IP65 is sufficient. Hot air balloons fly at a low speed (5~20km/h) without violent vibration, and they mainly face issues of dew (humidity 80%~90%) and dust. The 12S series (IP65) can fully meet the requirements, with a unit price that is only 70% of IP67 models. In addition, it can be installed without special tools, allowing non-professionals (such as hot air balloon pilots) to operate independently.
