MCIL&MCBH 5 Pins Series | SubConn Compatible 5 Pins Micro Underwater Connector Male & Female 5A 300V IP69K 8000m Stainless Steel Gold Plated
YingDiGe 5-pin subsea wet-mate micro circular connectors provide a compact, reliable electrical connection for ROVs, oceanographic instruments, underwater cameras, lighting systems, and other space-constrained marine equipment. MCBH5 bulkhead receptacles and MCIL5 inline cable connectors are designed to mate with corresponding SubConn® Micro Circular and Seacon-style configurations.
Built for immersion, salt spray, and high-pressure marine environments, the series combines corrosion-resistant shell options, gold-plated contacts, and flexible cable configurations. Select a matched male/female set or an individual connector to suit bulkhead-to-cable or cable-to-cable installations.
