The newest member of the industrial-grade Magnum™
Switches product line, the Magnum 6KM
Mobile Ethernet Switch from GarrettCom® Inc., is purpose-built
to withstand shock and vibration in harsh mobile environments including railroad
carriages, public service and emergency vehicles, mining equipment, shipboard, and
military vehicles. Possible applications are wide-ranging and include in-carriage
networking of IP-enabled infotainment systems, robotics, security and surveillance
systems, and mobile network devices on trains, mobile command centers, light
rail and buses, as well as passenger accommodation technology in a variety of
The design of the 6KM features M12-type heavy-duty screw-type
port connectors, technology borrowed from military equipment that is designed
to stand up to mobile vibration. It is also designed to meet or exceed
demanding industrial standards for mobile environments, including compliance
with IEC 61373 and IEC 60068-2-27 specifications for withstanding shock, and
with IEC61373, IEC 60068-2-6 FC specifications for withstanding
vibration. In addition, the 6KM design complies with the EN50155 and
EN50121-4 Railway Applications Standards, NEMA TS-2, and TEES for dc-powered
and PoE-powered traffic control equipment, is DNV compliant for marine
applications, is UL listed (UL 60950), and meets European CE and RoHS
The 6KM base unit has four 10/100 M12 copper ports
(PoE optional). Configuration choices include two Gigabit ports (either M12 copper
ports or LC-type fiber), and up to four 100Mb LC fiber ports, up to four
additional 10/100 M12 copper ports, or combinations of the two.
To protect sensitive electronics from even the
harshest environments, the 6KM Mobile Ethernet Switch is packaged in a
fully-enclosed steel case that acts as a heat sink, eliminating the need for
movable parts such as fans, and providing high EMI noise immunity. Able to
withstand operating temperatures ranging from -40 to 195F (-40 to 85C); with
optional conformal coating for corrosive environments, and with an IP52 rating
for dust and dirt resistance, the 6KM is capable of operating under hostile mobile
Prices for the Magnum
6KM Switches start at $1,000.
With a better understanding of materials’ response to load and temperature, researchers could potentially use the knowledge to improve design. The research could even help geologists studying plate tectonics.
