The BHB2 series 2-pin 600V DC / AC bulkhead power connectors are designed for battery-to-motor and battery-to-electronics power connections in underwater vehicles, subsea battery packs, and ROV power distribution systems. The 2-pin configuration provides a dedicated positive and negative power circuit in a single wet-mate connector — eliminating the need for two separate single-contact connectors and reducing connection time during ROV deployment operations. Rated at 600V DC/AC with current capacity up to 120A per contact, these connectors support mid-class electric ROV, AUV, and underwater drone power systems.
The bulkhead (BH) mounting variant is designed for panel, housing, or frame installation — the threaded flange provides a pressure-sealed bulkhead penetration rated to 4,000 m (400 bar). The female (F) and male (M) body variants are mated together: the BHB2F female accepts the BHB2M male pin insert. Gold-plated contacts throughout; EPDM O-ring face seal; anodised aluminium alloy body.

Order the BHB2F (female socket body) for the fixed bulkhead panel or housing — the socket body is permanently mounted through the panel. Order the BHB2M (male pin body) for the cable-side mating connector. Always pair one F and one M for a complete mated set. Contact us for pre-assembled cable-to-connector assemblies with specified conductor cross-section and length.
The BHB2M is a SubConn Power Battery Series bulkhead connector featuring 2 gold-plated contacts rated for 600 V DC/AC rms at 25 A per contact (maximum 50 A per connector). The chloroprene rubber body and nitrile O-ring sealing enable wet-mate panel feed-through at 300 bar depth with more than 500 mating cycles.
