The LMP-1802G-M12-10G-SFP-67-24 Light Layer 3 managed series switches are designed for industrial applications subject to high vibration and shock, water and dust. The IP67-rated switches offer 24- to 55-Vdc redundant power inputs through a five-pin M12 K-coded male connector. The total power of 240 W is available for supplying up to 16 IEEE 802.3af (PoE) and 802.3at (PoE+) devices. Built-in fault tolerance ensures against PoE system or PD overloads. In the cases of complete power failure, the device uses bypass technology to keep data communication flowing even if the switch is offline. The LMX-1802G-M12-10G-SFP-67 series has the same features but with no PoE functionality.
