MEMBER NEWS: MacArtney launches SubConn® Nano. Compact and versatile, engineered to meet customer demands

Due to market demand, MacArtney is excited to introduce the space and weight-saving ø12.7 mm SubConn® Nano, which builds on the globally trusted SubConn® design. This new Nano connector offers a versatile and robust performance, making it suitable for multiple applications and the increasingly compact design of underwater instruments, equipment, and systems.

The underwater industry continues to exceed the limits of what remotely operated and autonomous vehicles can achieve from the surface to the seafloor. As a result, there is a growing demand for solutions and technological advancements that can bolster high performance while maintaining a small footprint.

MacArtney aims to provide a comprehensive range of connectivity solutions catering to the diverse needs of our customers – ranging from high to low pin count connectors.

“Our customers have specifically requested a small-footprint SubConn splash-mate connector, which is why we are very thrilled to introduce the space and weight-saving Nano, designed to produce what we believe is a superior product with new features,” says MacArtney’s Paul Anthony, Global Business Manager Connectivity.
Moreover, it also enhances MacArtney’s workshop connectivity solutions worldwide, adding another capability to our range as a one-stop system solutions provider for the underwater industry.

Small footprint, big impact
The addition expands SubConn’s product portfolio, offering a new dimension of connectivity options. Despite its size, the market-driven SubConn Nano delivers powerful performance across a range of applications. Whether it’s sensors, AUVs, or other subsea devices, the SubConn Nano fits seamlessly.

The SubConn Nano connector draws upon the well-known and 45 years of field-proven design principles of the SubConn Circular and Micro Circular series. It has been designed with enhanced sealing capability, ensuring reliable performance even in challenging underwater environments. Its meticulously designed uniform contact size and layout maintain consistency and dependability.
This splash and wet-mate connector is manufactured from high-grade titanium and neoprene to withstand deep ocean depths and open-face pressure ratings. The 2½-turn locking sleeve has been specially crafted for seamless mating and prevention of anti-seizing.
Developed in response to industry needs, the SubConn Nano is tailored to meet real-world subsea challenges.

A legacy of reliability and innovation
With over four decades of connectivity proficiency, the SubConn portfolio exemplifies precision engineering and seamless adaptation to the dynamic underwater technology market. From the larger ø46.5 mm (25-pin SubConn Circular) to the ultra-compact ø12.7 mm (6-pin SubConn Nano), SubConn’s connectors offer reliability and innovation.
MacArtney maintains large quantities of connectors in stock globally and has multiple operations at strategic locations in North America, Europe, and the Asia Pacific. Additionally, MacArtney ensures the worldwide availability of SubConn connectors through exclusive agreements with distributors.

AREG is the original energy transition organisation, working on behalf of members to empower the energy supply chain and champion its expertise. Please get in touch if you have any questions or would like to find out more about membership.

AREG has played an important role in the growth of Scotland’s renewable energy sector, engaging the supply chain and developing the European Offshore Wind Deployment Centre. However, we are only at the very beginning of the transition that AREG was established to both lead and support so there are still opportunities for companies to get into the constantly evolving renewables supply chain. We look forward to continuing our work together as renewables builds on its place as Scotland’s main source of power, and as we seek to deliver real change in the crucial areas of heat and transport.

Aberdeen & Grampian Chamber of Commerce has worked closely with AREG since its formation. The recent progress in the developments of offshore wind projects by Equinor and Vattenfall are as a result of the work of the group over many years. The north-east is known as the oil and gas capital of Europe. At the Chamber, we believe the region must evolve its position to being recognised as the energy capital. Whilst hydrocarbons will continue to be essential in driving our economy for years to come, the generation of renewable resources will play an increasingly important role in providing cost-effective power, innovative development and economic growth.

The enthusiasm and dedication of the early group that would become AREG was fundamental in us choosing to launch All-Energy in Aberdeen. The first tiny show was held in 2001, and AREG’s Chairman at the time, Jeremy Cresswell, played such an active role that I often describe him in terms such as All-Energy’s ‘midwife’. All-Energy is now the UK’s largest renewable and low carbon energy exhibition and conference in terms of number of attendees, space booked, and number of exhibiting companies. As AREG became firmly established, their presence and support for the event grew spectacularly over the years. We thank them most sincerely for their invaluable input.


Vattenfall has forged a strong working relationship with AREG through the development of the European Offshore Wind Deployment Centre. AREG has worked tirelessly on behalf of the North East and it can take enormous credit for the growth of sustainable energy in the region and the path it has cleared for the region to capture further investment.


Aberdeen City and Shire is emerging as a key location for renewables by successfully transferring its world-class oil and gas expertise into the sector and AREG has done much to advance this through a broad range of initiatives. It has acted as a catalyst in driving further investment in the local economy by engaging with companies, Government, public bodies and existing projects and we have been pleased to support their efforts. Scottish Enterprise will continue to engage with AREG as we increase Scotland’s use of renewable energy.
