The high-current waterproof connector is a rubber-body four-contact plug for power-dense subsea loads: four large gold-plated pins plus a metal pilot pin in one molded insulator, on a heavy-jacket cable. It pairs with the matching rubber receptacle for thrusters, lamps and other high-draw equipment.
Product Highlights
- Four large contacts + pilot: big-diameter gold-plated pins carry the amps; the metal pilot pin keys and pre-aligns the pair.
- Rubber-body seal: the molded insulator is the seal — no separate gasket to forget at assembly.
- Heavy-jacket cable: supplied on a thick, abrasion-resistant round cable suited to deck handling.
- Simple mate / de-mate: push-fit into the rubber socket; no tools, no threading in the water.

Structure & Sealing
The plug’s metal base threads through the equipment housing and compresses the molded sealing shoulder. Inside the rubber body, four oversized pins are carried in individual bores around the central metal pilot. The receptacle’s rubber sockets grip the pins and complete the seal when the pair is pushed home.

FAQ
How much current can one pin carry?
It depends on pin cross-section and cable gauge — send the continuous and peak load and we will size it.
Is the pilot pin load-bearing?
No, the pilot pin is for alignment and grounding; the power pins carry the circuit.
Can this be mated underwater?
The rubber-body style tolerates wet handling; for frequent wet-mating ask about dedicated wet-mate series.
What depth is it rated for?
Ratings vary by build — send your operating depth for the confirmation.
