Ideal switch solution for industrial and hazardous environments

Product Information

The Comtrol RocketLinx ES8105F Ethernet Switch is a 4-port Fast Ethernet industrial switch with one 100BASE-FX fiber port and a fiber uplink feature which increases the transmission distance to 30KM. The RocketLinx ES8105F-S is housed in a slim industrial enclosure to save rail or panel space in compact system designs. For installation in hazardous or industrial environments, the RocketLinx ES8105 operates within an extended temperature range and provides IP31 protection to guard against dust and water. The ES8105F-S is an unmanaged switch that requires no user setup and immediately starts operating as soon as power is applied for true “plug-and-play” operation. The RocketLinx ES8105 supports 18 to 27VAC or 18 to 32VDC power inputs and provides built-in reverse power polarity protection. With the 1.5KV Hi-Pot isolation protection, CE/FCC/UL regulatory approvals, high MTBF, a 5-year warranty, and rugged aluminum design, the Comtrol RocketLinx ES8105 Ethernet Switch is the ideal switch solution for industrial and hazardous environments.
