IL16M Underwater Connector circular series In-Line Connector 16 Pin Contact Male
IL16M 16-contact SubConn Compatible circular subsea in-line connector, male (pins), 600 V DC/AC, 10 A, 7,000 m depth rating, wet-mateable, mates with BH16F / IL16F.
IL16M Circular Series In-Line Connector — Overview
The IL16M is an 16-contact Circular series subsea in-line connector, male (pins) face, wet-mateable and rated 10 A per contact at 7,000 m operational depth. It is factory moulded on a 2 ft (60 cm) chloroprene cable and couples through the characteristic locking sleeve, so the same part serves harness splices and hull penetrations.

Key Design Features
Wet-mateable: mate and demate in seawater; each contact carries its own moulded seal, so a single seal failure does not flood the connector.
SubConn Compatible: the same face geometry, contact pitch and 3/4-16 UNF-2A thread, so it retrofits existing 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 16-contact shell.
Pressure qualified: 1,400 bar mated design depth, 800 bar open face; a PEEK shell extends service to 300 bar where weight matters.
Field serviceable: locking sleeves, O-rings and snap rings are replaceable; lead, thread and cable lengths can be specified to order.
