SKU:
The HYSF MCIL4F is a miniature 4-core female inline watertight connector designed for high-performance underwater applications. Optimized for robust multi-signal and power transmission in compact setups including micro-ROVs, AUV sensor modules, underwater cameras, and marine scientific instruments where full waterproof integrity is critical. Precision-engineered with premium marine-grade materials, gold-plated contacts, and durable neoprene body, it ensures IP68 waterproofing and withstands 60 MPa pressure (6000 m depth). Superior corrosion resistance and low contact resistance establish it as the industry standard for deep-sea and offshore subsea connectors.
