MCIL&MCBH 2 Pins Series | SubConn Compatible 2 Pins Micro Underwater Connector Male & Female 10A 300V IP69K 8000m Stainless Steel Gold Plated
MCIL&MCBH 2 Pins Series | SubConn Compatible 2 Pins Micro Underwater Connector Male & Female 10A 300V IP69K 8000m Stainless Steel Gold Plated
YingDiGe 2-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. MCBH2 bulkhead receptacles and MCIL2 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.
