Is the waterproof rating of connectors for underwater robots (diving depth 500 meters) sufficient?

A: Connectors with customized IP69K+ waterproof rating (modified based on SF series) are required. They adopt a metal shell + double sealing structure, can withstand the pressure of 500 meters water depth (about 50MPa), and are resistant to seawater corrosion (salt spray test ≥2000h), adapting to underwater operation scenarios. The standard IP68 only supports 1.5 meters water depth and cannot meet the requirements.
