MCIL12M Micro Circular In-Line Connector — Overview

The MCIL12M is a 12-contact Micro Circular in-line subsea connector, male (pins) face, wet-mateable and rated to 10 A per contact (60 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.

12 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 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.
  • Moulded cable: factory-moulded strain relief, so there is no crimp joint to fail at the cable entry.

Notes for Selection

The 12-contact male in-line: pins are gold-plated brass, the body is moulded onto the cable, and the connector limit is 60 A. The listing title reads ‘Female’, but the M suffix is the male half — confirm the gender you need when ordering.

Custom configurations available Shell material (brass / 316L stainless steel / titanium / anodised aluminium / PEEK), thread and lead length, pin-out, cable length and hydrostatic test certificates can be specified to order. Send us your drawing or mating requirement for a quotation.
