IP50 aluminum housing Switch

GD18G a hardened 9-port Industrial Ethernet Switch, provides non-blocking wire-speed performance in harsh industrial environments. It also provides 8-port 10/100/1000BASE-TX RJ45 +1-port 1000Base-Fx  delivered in an IP40 rugged, strong case with redundant power system. Its slim case is suitable for such applications as surveillance system deployments, control management, and wireless service in climatically demanding environments with wide temperature ranges from -40℃ to 85℃.

The GD18G series provides flexibility to all kinds of 10/100Mbps Ethernet Media on RJ-45 port and performs highly stable fiber performance.

The GD18G series is packaged in a compact IP40 case that allows either DIN rail or panel mounting to have efficient usage of cabinet space. It provides power supplying with a wide range of voltages for worldwide operation. It also offers dual-redundant, reversible polarity 12V DC to 52V DC power supply inputs for high-availability applications requiring dual or backup power inputs.
