Sixnet® ET IP67 Industrial Ethernet Switches

Brand: Red Lion Controls

These high-performance switches offer an ideal Commercial Off-The-Shelf (COTS) military solution for battlefield communications, combat vehicles and avionics shipboard as well as other industrial applications that require rugged reliability in extreme environments.

With military equipment subject to harsh climates, varying temperatures, shock and vibration, defense requirements are mission critical. Equipment has to be built to withstand extreme stresses without sacrificing performance. Sixnet’s IP67 Ethernet switches are designed to reliably provide high-performance connectivity for the harshest defense applications.

Military rated to support extreme defense conditions, our products link in-vehicle communication systems to support a host of military applications on the land, in the air and on sea. These include land vehicles, ground support facilities, missile delivery systems, bombers, aircraft, UAVs and naval vessels.
