MCIL4F Miniature 4-Pin Female Inline Underwater Connector

MCIL4F is a miniature 4-pin female inline underwater connector from HYSF SUBSEA, designed for compact subsea power and signal connections. Its four-contact female interface provides a removable cable connection for ROV systems, AUV sensor modules, underwater cameras, marine monitoring equipment, and oceanographic instruments.This 4-core female underwater cable connector features a neoprene body and gold-plated copper contacts. The miniature inline design helps equipment builders integrate electrical connections into underwater assemblies where installation space and cable routing require careful planning. MCIL4F can be incorporated into cable-to-cable or cable-to-bulkhead arrangements with a confirmed compatible male connector.The HYSF SUBSEA miniature 4-core connector specification lists an electrical rating of 550 V at 10 A, insulation resistance greater than 200 MΩ, and contact resistance below 0.01 Ω. The published working-depth specification is 6000 m, with a pressure rating of 60 MPa. Cable construction, mating configuration, and operating requirements should be specified for the complete assembly.
