The Smallest Industrial Gigabit Ethernet Switch
GigaBlox Rugged is a very small layer 2 unmanaged ethernet switch that fits four 10/100/1000Mbps copper ethernet ports in an ultra-compact 50mm x 55mm form factor. GigaBlox Rugged is designed to be a more rugged and more capable upgrade to our GigaBlox product and is designed for space, weight and price-sensitive (SWaP) industrial, mobile and military applications.
GigaBlox Rugged has an input voltage range of 5 to 60V with transient, overvoltage, and reverse polarity protection on board, meaning it can be dropped directly into a system powered by unregulated bus voltage. This wide input voltage range is particularly advantageous in motor control systems where additional voltage headroom is required due to motor voltage transients.
The -50°C to +110°C ambient operation range is achieved by using automotive/military-grade components whose operation is rated for -50°C to +125°C.

GigaBlox Rugged does not require any configuration and works “out-the-box” as an unmanaged layer 2 switch.
GigaBlox Rugged supports jumbo frames up to 9,000 bytes, meaning it works well with GigE Vision cameras.
