SubConn Circular Series

The SubConn® Circular series forms the basis of the technology that characterizes most SubConn® products available today. First introduced in 1978, these connectors are widely recognized as a dependable and rugged connectivity solution for underwater and harsh marine environment applications. SubConn® Circular connectors are available in various standard size configurations with 1 to 25 contacts.

The SubConn® Circular series offers the ability to combine signal and power within a single connector. SubConn® Circular connectors are manufactured from high-grade chloroprene rubber with different types of body material and feature a high depth rating. The connectors are available in different standard shell sizes with contacts rated at 600 V up to 10 A. SubConn® Circular connectors are available in the bulkhead, inline, Pressure Balanced Oil Filled (PBOF), and field-installable overmold versions. All bulkhead connectors come with color-coded or numbered Teflon (PTFE) leads.

For easy integration with systems and equipment, SubConn® Circular connectors are available with dedicated cables, locking sleeves, pressure-proof dummy connectors, and other accessories. All SubConn® cables are manufactured from flexible and water-resistant chloroprene rubber or polyurethane (PUR). The characteristic SubConn® locking sleeves are manufactured from injection molded polyoxymethylene (POM) or stainless steel and come with stainless steel retaining snap rings.
