rating while using standard RJ45 connectors. MDE45 series M12 threaded overmolded cables, receptacles and field-wirable plugs use M12 four-wire (D-coded) connectors with two pairs of Cat. 5e cables or M12 eight-wire (A-coded) connectors with four pairs of Cat. 5e cable. The MDE45 is used in industrial Ethernet applications and has teal cable using twisted pairs of wires inside. Unmanaged Fast Ethernet switches protect themselves from receiving too many broadcast packets. Each switch provides two redundant power inputs that can be connected simultaneously to a range of dc power sources for backup.
