Unmanaged Ethernet switch

Viper-008

The Viper 008 is a rugged unmanaged Ethernet switch designed for applications with severe operating conditions and extreme environments. The Viper 008 meets the EN 50155 standard for electronic equipment used in railway applications. The super slim and extra robust housing is sealed to IP 65 and together with an MTBF (Mean Time Between Failure) calculated to more than a 100 years makes these units ideal for situations where mechanical stress, moisture, condensation, dirt or continuous vibrations could adversely affect the function of standard Ethernet switches.

The unit is well prepared for use in harsh industrial environments. The IP 65 sealed metal case and rugged M12 front connectors of the unit makes it robust and allows for the surrounding air temperature to be between –40 to +70°C. There are no sensitive or fragile components, hardening the product against shock and vibration making these units suitable for rolling stock usage. The power supply operates over a wide input range from 24 to 110 VDC ±40%.
