Industrial automation Gigabit cabling for PROFINET
Until now, PROFINET solutions have been based on Fast Ethernet operating at 100 Mbit/sec, but these products, which include all the familiar Fast Ethernet RJ45 PROFINET cabling components, will allow future PROFINET applications to work in conjunction with a Gigabit Ethernet platform.
PROFINET systems based on these products will offer more variety and performance as well as being faster. They will also give users the option of incorporating standard Gigabit devices into PROFINET solutions, with the cabling containing eight wires instead of four.
For RJ45 wiring, Harting has defined the so-called modularity principle in a company standard which guarantees the mechanical compatibility of the RJ45 connector with the various IP65/67 housings such as the Han 3A or PushPull V.14 (AIDA interface).
For PROFINET users, this means that all the 4-wire RJ45 PROFINET cabling components are now available in an 8-core version. In addition to the established PROFINET cabling components such as type A, B or C cables and connection technology based on RJ45 or M12, 8-wire cabling has also added a new element: the control cabinet cord. This RJ45 system cord, newly defined by the PNO (PROFIBUS Nutzerorganisation e.V.), is designed for use in control cabinets and IP20/30 environments. It features an 8-core design and is based on an AWG26 cable. This gives it significant flexibility, making it ideal for space-saving installation for short links or for connections that can only be achieved through tight bending radii in the cabinet.
Harting offers a wide range of factory-tested control cabinet cords. They are fully assembled with the RJ45 connectors over-moulded with “DualBoot”, and are designed to be extremely robust.
