Shown here are the types of products that are used as communication networks, which are deployed into the higher M.I.C.E. rated environments. The typical requirements are for a higher level of protection on the connection, such as IP65/57, for shielding as the environment is noisy, and of course, the runs are shorter. For the connection styles of higher rated M.I.C.E. elements, the most common is an M12 connector, which is a barrel connection, in which the wires are terminated inside by either a screw termination or IDC (insulation displacement connection) style. The M12 is the standard connector that is used on the plant floor for almost all of the connections on the machine, such as a sensor. The coding of the M12 is dependent on the type of connection that is being made. For example: for 2 pair Ethernet, the coding is referred to as a D-code and for 4 pair it is referred to as an X-code. The patch cords are typically 600V rated as there is a lot of higher voltage devices (M.I.C.E. E=3 rated environment) in the area and this style of a patch cord helps to eliminate the noise from the higher voltages.
