Designed to maintain reliable performance in rugged industrial environments, the MES line complies with UL, CE, FCC and RoHS standards. The MES switches provide redundant DC power inputs to ensure continual operation if one power source fails. Both the MESP and MESM feature 10/100BaseT(X) (RJ45) connectors and support IEEE 802.3/802.3u/802.3x. The products offer broadcast storm protection, use rugged, high-strength housing and are designed to operate reliably in temperature ranges from 14°F to 158°F. MES switches can be mounted to a wall or DIN rail.
