Description
Westermo Viper Unmanaged Series Westermo Viper Series EN 50155 Unmanaged 8 or 12-Port Ethernet Switches, M12 Connectors, 24-110 VDC Powered, -40 to +70 deg. C
The Viper rugged unmanaged Ethernet switches are designed for applications with severe operating conditions and extreme environments. The switches meets the EN 50155 standard for electronic equipment used in railway applications. The super slim and extra robust housing is sealed to IP65 and together with an MTBF (Mean Time Between Failure) calculated to more than a 100 years make these units ideal for situations where mechanical stress, moisture, condensation, dirt or continuous vibrations could adversely affect the function of standard Ethernet switches.
The units are well prepared for use in harsh industrial environments. The IP65 sealed metal cases and rugged M12 front connectors of the unit makes it robust and allows temperatures from -40 to +70 deg. C (-40 to +158 deg. F).
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%.
