Definition of Cable Category at Profinet
For cabling in line with the Profinet standard, all cables must comply with a cross-section in line with AWG 22, and the selection of the connector must conform with Profinet.
There are three fundamental cable categories therefore:
Category A: fixed installation with solid wire
Category B: flexible deployment, occasional movement as well as vibration
Category C: genuine mechanical use, such as dragline operation or robotics
Nowadays, there are various different plugs available in the area of networks in the field of automation, such as the RJ 45 standard plug, the RJ 45 Y-Con, the RJ 45 industrial plug and the M12 4-pin plug, but not all plugs conform with Profinet and not every cable fits into every plug! Nexans can offer a suitable cable for every application.
