MCBHRA6M IP69 ROV underwater robot miniature right angle waterproof 6pin ip69 cable connector

MCBHRA6M Micro Circular Bulkhead Connector — Overview

The MCBHRA6M is a 6-contact Micro Circular bulkhead subsea connector, male (pins) face, wet-mateable and rated to 10 A per contact (50 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.

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 50 A connector limit for the 6-contact shell.
• Pressure qualified: 1,400 bar mated design depth, 800 bar open face, so the face survives handling and storage unmated.
• Brass / 316L stainless steel / Titanium body: matched to the housing material to avoid galvanic couples; brass, 316L stainless, titanium, anodised aluminium and PEEK are available across the range.
• Right-angle exit: routes the leads sideways behind the panel where vertical clearance is not available.

Typical Applications

Compact ROV builds, robot arms and gimbals, pods with limited rear clearance, tight instrument housings.

Notes for Selection

The 90° body routes the leads sideways behind the panel, saving the vertical clearance a straight bulkhead needs. Same contact set and ratings as the straight MCBH6M; IP69 for high-pressure wash-down and splash zones.
