Micro Wet Bulkhead Connector - 4 Way Female MCBH4F Brass Material

MCBH4F Micro Circular Bulkhead Connector — Overview

The MCBH4F is a 4-contact Micro Circular bulkhead subsea connector, female (sockets) face, wet-mateable and rated to 10 A per contact (30 A per connector) at 7,000 m working depth. It mounts through a standard 7/16-20 UNF-2A hull penetration and is supplied with colour-coded PTFE leads for direct splicing inside the housing.

4 Contacts 600 V AC/DC 10 A per Contact 7,000 m Depth 500+ Wet Matings IP68

Key Design Features

• Wet-mateable: mate and demate in seawater; each contact carries its own moulded O-ring seal, so a single seal failure does not flood the connector.
• SubConn Compatible: identical face geometry, contact pitch and 7/16-20 UNF-2A thread, so it retrofits existing SubConn panels and harnesses without re-machining.
• Gold-plated contacts: brass UNS-C36000 contacts hold contact resistance below 0.01 Ω across the full 500-cycle life.
• 10 A per contact: rated current with a 30 A connector limit for the 4-contact shell.
• Pressure qualified: 1,400 bar mated design depth, 800 bar open face, so the face survives handling and storage unmated.
• Brass body: matched to the housing material to avoid galvanic couples; brass, 316L stainless, titanium, anodised aluminium and PEEK are available across the range.

Typical Applications

Multi-sensor pods, four-wire instrument links, combined power and two signal channels through one penetration.

Notes for Selection

The female bulkhead keeps the sealed socket bores inside the housing, which is the usual choice when the mating cable is handled on deck.
