Managed Ethernet Switch mit Routingfunktionalität und EX-Zulassung


Lynx 210 EX is a layer 3 managed industrial Ethernet switch, powered by the Westermo WeOS network operating. Independently tested for IECEX and ATEX by Baseefa, as well as Class 1 Division II by FM approval, Lynx is the perfect solution for hazardous area applications in any part of the world.

Lynx is the most compact and has the lowest power requirements in this class of switch. Lynx has 8 10/100 Mbit/s ports in addition to 2 ports which can be fitted with Gbit or 100 Mbit SFP transceivers.

Only industrial grade components are used which gives Lynx an MTBF of 630,000 hours and ensures a long service life. A wide operating temperature range –40 to +70°C (–40 to +158°F) can be achieved with no moving parts or cooling holes in the case. Lynx has been tested both by Westermo and external test houses to meet many EMC, isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial environments and rail trackside application.

WeOS has been developed by Westermo to allow us to offer cross platform and future proof solutions. WeOS can deliver 20 ms ring recovery performance even for networks with video or EtherNet/IP traffic. For EX approved transceivers and more WeOS functionality please see the transceiver and WeOS datasheets.
