mechanical, ingress, climatic, electromagnetic (MICE)

Data cables and data connectors in industrial applications are not only selected according to electrical and transmission-specific properties, but also according to the insulating materials and the associated environmental conditions and stresses.

While ingress protection( IP) only defines the types of protection against solid and liquid substances, the MICE concept focuses on mechanical stresses (M, Mechanical) such as shock, torsion and impact resistance, ingress (I, Ingress) of objects and moisture, resistance to climatic and chemical influences (C, Climatic) and immunity to electromagnetic interference (E, Electromagnetic). The four MICE parameters mentioned above are divided into three classes: Normal requirement is class 1, simple (2) and increased (3). The four parameters are specified individually in the data sheets with their respective classes, for example as M2/I3/C2/ E3.

The MICE concept forms a systematic description of climatic and mechanical stresses. MICE describes the mechanical properties, the sealing properties, the climatic properties and the electromagnetic properties of the cables.

In addition to the above-mentioned stresses, the MICE concept also makes distinctions concerning the area of application of the data cables. These criteria, known as severity levels, are concerned with the office environment (1) and with different industrial applications with medium requirements (2) and with harsh industrial applications (3). A cable for medium industrial requirements, as used in Industrial Ethernet, has the designation M2/I2/C2/E2 according to this nomenclature.

In general, the MICE concept is intended to complement the 50173 and IEC 63171 standards for SPE cabling. It offers users the possibility to select data cables for industrial applications for their specific requirements and application focus. Since the values for the four MICE criteria are printed directly on the cable, the user can identify the MICE specifications on the basis of the cable.
