IL25M Underwater Connector circular series In-Line Connector 25 Pin Contact Male

IL25M Circular Series In-Line Connector — Overview

The IL25M is a 25-contact Circular series subsea in-line connector, male (pins) face, wet-mateable and rated 10 A power / 5 A signal 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.
• Mixed contact set: three 10 A power contacts in gold-plated brass plus twenty-two 5 A signal contacts in gold-plated beryllium copper.
• 10 A power / 5 A signal per contact: rated current with a 60 A connector limit for the 25-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.

Notes for Selection

The 25-contact layout splits into 3 power contacts at 10 A and 22 signal contacts at 5 A, with a 60 A connector limit; contacts 2, 4 and 6 are gold-plated brass, the rest gold-plated beryllium copper.
