DS105 is a cost effective industrial 5-port Ethernet switch for industrial Ethernet connection. The rugged design can stand for harsh environment and wide temperature (from -40 to 75°C) use. Ultra low power design consumes less than 1W during full traffic. The compact size can fit in for space limited installation such as vehicle wall-mounting or Din-mount for cabinets. Micro USB DC 5V power input is flexible for installation.
