The ILB3 series 3-pin 600V in-line wet-mate power connector is the cable-to-cable equivalent of the BHB3 bulkhead connector — providing a field-separable 3-circuit power junction for subsea power cables. The in-line configuration suits tether termination points, mid-cable power distribution, and portable ROV systems where quick-disconnect 3-phase or 3-circuit power connections are required without panel mounting. Rated 600V DC/AC at up to 90A per contact; depth rated to 4,000 m.
ILB3F female and ILB3M male pair together with the same coupling nut locking system as all ILB/BHB series connectors — ensuring positive lock and vibration-resistant mating. The connector is cross-compatible with BHB3 series for mixed bulkhead and in-line system topologies. Gold-plated contacts; EPDM O-ring seal; anodised aluminium alloy body.

| Depth rating | 4,000 m (400 bar) |
The ILB3 in-line connector suits mid-cable or tether-end separable joints. The BHB3 bulkhead connector suits panel-mount applications on ROV frames and junction boxes. Electrically and mechanically identical — male and female variants are cross-compatible across the BHB/ILB family, allowing mixed-topology power systems to use a common connector standard.
The ILB3F is a SubConn Power Battery Series in-line connector featuring 3 gold-plated contacts rated for 600 V DC/AC rms at 25 A per contact (50 A max per connector). Chloroprene rubber body and nitrile O-ring seal enable wet-mate operation at 300 bar depth with >500 mating cycles. Inline female for cable extension and power disconnect.
