We supply a wide range of hard anodised SubConn® Connectors which are specially designed for underwater applications.

The black hard anodised aluminium SubConn® connector is designed to help prevent cathodic de-bonding caused by a difference in potential between the connector and surrounding equipment.

The hard anodised aluminium is non-conductive and is stronger than other non-conductive materials, including PEEK, and is designed to have a long life.  The hard anodised SubConn® series is based on the standard SubConn® series and includes standard circular, micro and low-profile connectors. They are manufactured from high grade neoprene and are available in a range of shell sizes with up to 16 contacts rated for 300 to 600 V at 5 to 15 Amps, depending on the contact configuration.

Standard products include in-line and bulkhead connectors with pressure proof dummy connectors. Bulkhead connectors come with Teflon leads. Locking sleeves are manufactured from injection moulded Delrin with stainless steel retaining snap rings.  Most in-line cables are water resistant SOOW flexible cables. 2-16 pin connectors are available as field installable overmould in-line connectors.
