micro series bulkhead 12 pins female connector with brass material MCBH12F

MCBH12F Micro Circular Bulkhead Connector — Overview

The MCBH12F is a 12-contact Micro Circular bulkhead subsea connector, female (sockets) face, wet-mateable and rated to 10 A per contact (60 A per connector) at 7,000 m working depth. It mounts through a standard 5/8-18 UNF-2A hull penetration and is supplied with colour-coded PTFE leads for direct splicing inside the housing.

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 5/8-18 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 60 A connector limit for the 12-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-bus instrument packages, ROV tether breakout panels, combined power and data for subsea control modules.

Notes for Selection

Twelve contacts give headroom for several RS-485/RS-232 buses plus dedicated power rails and shields through one wet-mateable interface. This shell uses the 5/8-18 UNF thread, with 3/4-16 UNF available to order.
