The HYSF MCIL21M is an extremely high-density 21-core male inline watertight connector engineered for the most complex deep-sea systems requiring extensive multi-channel capabilities. Ideal for large autonomous underwater vehicles, advanced ROV platforms with full instrumentation, underwater communication hubs, marine seismic equipment, and oceanographic arrays demanding ultimate waterproof performance. Built with marine-grade neoprene, gold-plated contacts, and precision construction, it delivers IP68 sealing and pressure resistance up to 60 MPa (6000-meter depth). Exceptional corrosion resistance and low contact resistance ensure reliable operation in offshore exploration and high-pin-count subsea connections.
