Buoyant-U8M12 series
8- port Industrial Gigabit Unmanaged IP67 switches

This unmanaged Ethernet switch range with its upto 6-8 10/100/1000 ethernet ports and upto to 2 1 Gbps SFP ports is suitable for a variety of industrial applications because of their very compact IP67 design. The tough industrial IP67 enclosure design with wide temperature is suitable for mounting on a DIN rail and can be easily integrated into any Industrial environment that requires water resistance. The switch also includes the ability to allow users to enable or disable the Quality of Service (QoS) function, and broadcast storm protection (BSP) with DIP switches on the outer panel.


This series of switches are high performance unmanaged switches, providing wide temperature operation with PoE and 1 Gbps fiber over SFP. With extensive market specific certifications it caters seamlessly to markets ranging from smart cities, surveillance, traffic, railway and Industrial Automation.


It supports power budget of up to 245W for PoE/PoE+, over 8 ports, and is ideal for connecting PoE-powered end devices such as IP cameras, phones, wireless access points, sensors, and more.
