The 21 pin SubConn® series of connectors has been designed for underwater technology projects requiring multiple signal connections and low voltage.

This new SubConn® has 21 contacts for data and signal and is based on the existing B size series, offering the assured quality and reliability already proven in decades of use offshore. Using the same dimensions as the standard B size connector also makes it compatible with the same locking sleeves, nuts and other accessories.

The series is available as a circular connector, in bulkhead version with ⅝” thread and in an over mould (OM) version. The 21 signal contacts are all in the Subconn® micro pin size used by Subconn® in the Micro connector series for many years.
