Standard Circular

The standard circular SubConn® connector is the original underwater mateable connector and is still the most popular connector type today. The range is still the preferred choice for underwater applications, and has a well-deserved reputation for being cost efficient and rugged solution for underwater and harsh environments.


The SubConn® circular series is manufactured from high grade neoprene with naval brass bulkhead bodies and is available in 4 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 coloured 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. 2-12 pin connectors are available as field installable overmould in-line connectors.
