EHG3305

EHG3305 is a slim, entry-level unmanaged switch with 5 RJ-45 ports and strict QoS packet prioritization according to 802.1p. Designed for industrial and especially for hazardous locations, it fits into small spaces in cabinets or between walls, and complies with CE, FCC and UL standards, while featuring a robust metal housing.
Redundant power inputs allow simultaneous connection to wide-range DC power sources, so in case one of the power inputs fail, the other live source automatically acts as a backup to provide power.
