MCBH3F Micro Circular Bulkhead Connector — Overview

The MCBH3F is a 3-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.

3 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 3-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.

Notes for Selection

The female face is recessed and individually sealed per contact, protecting the sockets during deck handling and unmated storage.
