Fischer KEYSTONE™ delivers easy connectivity and efficient power management for soldier-worn digital equipment

March 29, 2023 · 2 min read

The new Fischer KEYSTONE™ power and data hub with 6 ports is an innovative wearable solution to the tactical connectivity challenge presented by digital modernization programs, i.e., more data, higher speeds, greater power and less weight in harsh environments.


The new tactical connectivity allows dismounted soldiers to connect and manage multiple communications and digital devices through a single hub.


Fischer KEYSTONE™ comprises a 6-port tactical hub, Fischer KEYSTONE™ 6, a power management app available as a standalone app and/or as a plug-in for the Android Team Awareness Kit (ATAK), and customized cable assemblies with connectors designed to meet NATO STANAG 4695 standards.

The soldier connectivity challenge

Dismounted soldiers wear multiple communications and sensing devices that increase both their situational awareness and their ability to rapidly identify potential threats and take decisive action in the battlefield. They require high levels of power delivered from a supply which they must carry. At the same time, their digital equipment must efficiently and reliably move massive amounts of data, including voice, video and other data types, across multifunctional C4ISR/C5ISR devices and systems. This data must move in harsh physical environments, with minimal signature, without distracting the soldier from the mission and environment.

Fischer KEYSTONE™ solves the tactical connectivity challenge by integrating the power and data flows from all soldier-worn digital devices and a single battery through a lightweight ergonomic component.


It enables soldiers to connect and power their digital gear easily and reliably, and to efficiently manage the flows of data (USB 2.0 and SMBus) and power (100 W – 5 A max) through a single source controlled from an easy-to-use app on their EUD.

“The soldier is the center of the digital transformation in armed forces,” highlights Jonathan Brossard, CEO of Conextivity Group, parent of Fischer Connectors. “Our experts have tackled the soldier connectivity challenge with a Swiss-engineered hub which meets tough military standards. Soldiers already know how to use it – they wear it, connect it, and go.”

Fischer KEYSTONE™ provides military OEM integrators with a competitive solution comparable to the U.S. Army’s Next Generation Hub (NGH). Olivier Thormann, Fischer KEYSTONE™ Product Manager, explains: “Fischer KEYSTONE™ is a complete connectivity solution that meets the performance requirements of soldier modernization and digital transformation programs such as U.S. Army 2030.”


Fischer KEYSTONE™ is Swiss-engineered for MIL-spec digital connectivity with Fischer Connectors’ world-renowned technologies in ruggedness, sealing, miniaturization and data transmission.
