Member News: MacArtney introduces the 9-contact SubConn® connector for optimal data integrity

MacArtney is excited to launch the newest SubConn® Micro Circular series member: the 9-contact connector. With enhanced features designed to minimise signal interference, this connector ensures optimal data accuracy and efficient underwater operations. 

Engineered in direct response to customer and end-user demands for better performance, this new addition to the Micro Circular series features optimal data integrity, minimal signal loss, and high data fidelity – critical attributes for advanced underwater applications. 

“Maintaining signal integrity is crucial in the often harsh subsea and marine environments, and the new connector is designed to meet this challenge,” says Global Business Manager Connectivity, Paul Anthony. ”With enhanced shielding, the 9-contact connector minimises electromagnetic interference, providing a stable and uninterrupted connection for your underwater equipment.” 

Seamless integration capabilities
Thanks to the standardised thread size 7/16-20 UNF, the 9-contact SubConn connector is easily integrated with existing systems and simplifies installation. It enables quick adaptation to different underwater instruments and equipment without needing custom solutions. 

“With the ability to rapidly adapt the number of contacts, users can easily modify systems to meet evolving demands,” says Paul Anthony. “This enhances operational flexibility, which is essential when replacing a connector or integrating new equipment. It also reduces downtime and simplifies the installation process, making it ideal for various underwater applications, such as AUVs, ROVs, sensors, and multiplexers.” 

Furthermore, the 9-contact connector’s design and versatility facilitate integration into the increasingly compact design of underwater technology solutions while still meeting complex data and power transmission needs with its multi-signal capabilities. 8-contact connectors are typically used for signal transmission, and some users have requested an additional contact for enhanced security. The ninth contact in this connector is intended for a screen, providing an extra layer of data protection and ensuring reliable performance. 

Built to withstand harsh underwater conditions
The SubConn Micro Circular connector series provides dependable performance even at great ocean depths. High-quality materials such as chloroprene rubber for the connector body and options including brass, stainless steel, titanium, anodised aluminium, or PEEK for the bulkhead body resist corrosion and pressure to ensure long-term durability and reliability.  

Each of the nine contacts is rated at 5 A, with a maximum of 20 A per connector, meeting the demanding requirements of underwater applications. The Micro Circular connectors are manufactured from high-grade neoprene and feature a high ocean depth rating, reducing the need for frequent maintenance and replacements. 

Globally trusted connectivity solutions
Easily recognisable by their red locking sleeves, SubConn underwater mateable connectors have been trusted by customers worldwide since 1977. MacArtney collaborates closely with SubConn to meet market demands, developing and testing the complete range for applications spanning from shallow water use to some of the deepest ocean locations on Earth.  

MacArtney supports the entire SubConn range and holds substantial stock, ensuring immediate access to SubConn connector solutions locally and globally.

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.
