MCBH4M Miniature 4-Pin Male Bulkhead Underwater Connector

MCBH4M is a miniature 4-pin male bulkhead underwater connector from HYSF SUBSEA, designed for electrical connections through subsea equipment housings. Its four-contact male interface provides a housing-mounted connection point for a compatible female underwater cable connector, supporting detachable power and signal connections.This threaded subsea bulkhead receptacle is suitable for pressure housings, underwater junction boxes, ROV control enclosures, and marine instruments. Once installed, the bulkhead connector remains attached to the housing while the external cable can be connected or removed for equipment assembly and servicing.MCBH4M combines gold-plated contacts and neoprene overmolding with 316L stainless steel or titanium body options. The miniature four-core series specifications include an electrical rating of 550 V at 10 A and a published working depth of 6000 m at 60 MPa. Select the body material and complete mating configuration to suit the equipment design and operating environment.
