Q: How to protect connectors from moisture in electrical control cabinets with high humidity (>90%)?

A: Prioritize connectors with an IP67 protection rating (such as the WF series). The shell is made of PA66 + glass fiber material (with better moisture resistance than ordinary plastics), and the contacts are silver-plated (anti-oxidation). Meanwhile, install a dehumidifier (such as a semiconductor dehumidification module) inside the control cabinet to keep the humidity below 60%, avoiding short circuits caused by condensation inside the connectors.
