MCIL&MCBH 3 Pins Series | SubConn Compatible 3 Pins Micro Underwater Connector Male & Female 10A 300V IP69K 8000m Stainless Steel Gold Plated
YingDiGe 3-pin subsea micro circular connectors provide a compact watertight electrical connection for ROVs, oceanographic instruments, underwater cameras, lighting systems, and other space-constrained marine equipment. MCBH3 bulkhead and MCIL3 inline configurations are designed for mating with corresponding SubConn® Micro Circular interfaces; confirm the exact model and mounting dimensions before replacement.
Built for immersion, salt spray, and high-pressure marine environments, the series combines corrosion-resistant shell options, gold-plated contacts, and flexible cable configurations. Choose a matched male/female pair or an individual connector for bulkhead-to-cable or cable-to-cable installations.
