BH5M Underwater Connector Circular Series Bulkhead Connector 5 Pin Contact Male
BH5M 5-contact SubConn Compatible circular subsea bulkhead connector, male (pins), 600 V DC/AC, 10 A, 7,000 m depth rating, wet-mateable, mates with IL5F / BH5F.
BH5M Circular Series Bulkhead Connector — Overview
The BH5M is a 5-contact Circular series subsea bulkhead connector, male (pins) face, wet-mateable and rated 10 A per contact at 7,000 m operational depth. It mounts through a standard hull penetration and is supplied with colour-coded PTFE leads for splicing inside the housing.

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 7/16-20 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 30 A connector limit for the 5-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.
