Lynx 105 is a layer 2 managed industrial Ethernet switch, powered by the Westermo WeOS network operating. Independently tested for IECEX and ATEX by Baseefa, 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 4 10/100 Mbit/s ports and 1 RS-232 port.

Only industrial-grade components are used, which gives Lynx an MTBF of 677,000 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 applications.
