BIRNS made a splash at Oi at the company’s Power Forward event, with the celebration of the company’s 70th anniversary, and the launch of a new high amperage subsea connector se- ries, the 225 Amp BIRNS Meridian line. The Meridian line, a robust, custom engineered dry-mate connector series is open face rated to 6km, and is well-suited for battery packs and thrusters for crewed and uncrewed subsea vehicles that re- quire high amperage power transfer. Select sizes are already being DNV type-approved for 6km rated crewed submers- ibles. BIRNS Meridians are compact, and feature several pin con? gurations, with more in design for release later this year.

The M40 pin con? guration has a single 85 square millime- ter/3-000 contact. Both standard and reverse gender versions

MacArtney introduced a space and weight-saving ø12.7 mm

SubConn Nano, a Nano connector which offers a versatile and robust performance, making it suitable for multiple applica- tions and the increasingly compact design of underwater in- struments, equipment and systems. This splash and wet-mate connector is manufactured from high-grade titanium and neo- prene to withstand deep ocean depths and open-face pressure ratings. The 2.5-turn locking sleeve has been specially crafted for seamless mating and prevention of anti-seizing.
