How does HYSF prevent Galvanic Corrosion (Dissimilar Metal Corrosion)?

Galvanic corrosion occurs when two different metals interact in seawater. HYSF minimizes this risk by selecting materials that are close on the Galvanic Series (e.g., 316L Shell + Gold Plated Contacts). We also recommend using Sacrificial Anodes on your ROV frame and isolating the connector shell from the frame using POM/Plastic isolation washers.

Your connector is part of a larger electrical system.

Material Matching: We advise against mating a Stainless Steel connector to an Aluminum housing without isolation, as the Aluminum will corrode rapidly to protect the Steel.
Isolation: We supply non-conductive mounting kits (washers/sleeves) to electrically isolate the bulkhead connector from the host chassis.
Design Advice: Always ensure your vehicle has adequate Zinc or Magnesium anodes protecting the entire assembly.
