Unmanaged Industrial Ethernet Switch – Viper-012
The Viper-012 is a basic 12 port westermo unmanaged industrial ethernet switch designed to meet the full requirements of the rail vehicle market. The incredibly compact and robust housing ensures the unit can be built into tight and environmentally hostile spaces. As is critical for all equipment to be installed in rail vehicles, the Westermo Unmanaged Ethernet Switch Viper-012 has been externally tested across the complete spectrum of standards required by EN50155 ethernet switch.
Westermo understand that systems on railcars are required by the EN50155 ethernet switch standard to have a useful life of 20 years, so as well as using the highest quality components to deliver extended MTBF figures, we also implement features like the Gore-Tex® membrane in the IP65 enclosure to prevent water build up in the units. Due to the high vibration environment of the rail industry, we have also developed the Viper case with integral threading for the M12 connectors to ensure the IP65 seal is maintained for the life of the product.
The EN50155 ethernet switch standard requires mandatory performance and isolation testing. Not only does Westermo meet these, we exceed them in order to meet the additional manufacturer requirements for train control. Westermo’s Swedish factory has been building Ethernet switches for the railcar market for many years now and understands the measures that are required to provide the highest quality
