MCIL8F Micro Circular In-Line Connector — Overview

The MCIL8F is an 8-contact Micro Circular in-line subsea connector, female (sockets) face, wet-mateable and rated to 10 A per contact (50 A per connector) at 7,000 m working depth. It terminates a free cable and mates mid-run, with no panel or chassis mount required.

8 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 50 A connector limit for the 8-contact shell.
  • Pressure qualified: 1,400 bar mated design depth, 800 bar open face, so the face survives handling and storage unmated.
  • Moulded cable: factory-moulded strain relief, so there is no crimp joint to fail at the cable entry.
