SWD-HE-8TX Hardened 8 Port Unmanaged Switch

TSWD-HE-8TX Hardened Layer 2 Switchhe SWD-HE-8TX is an unmanaged hardened Ethernet switch designed to be used in hostile environments such as Electrical Substations or Railway infrastructures.

SWD-HE-8TX comes in a robust and IP30 aluminum enclosure. It is made of industry grade components to operate over a wide –40 to +75 °C temperature range and even up to +85 °C for limited periods of time. The SWD-HE-8TX is not only shock and vibration resistant, but also it complies with the most severe Electromagnetic Immunity standards for railway infrastructures (EN 50121-4) and Electrical Substations (IEC 61850 and IEEE 1613).
