Flexible Cabling Systems: Han® PushPull Cable-to-Cable Housings

The new Han® PushPull cable-to-cable housings from HARTING enable flexible cabling for the transmission of Energy, Data and Signal to protection type IP 65/67. They offer decisive advantages for device connection and the installation of switch cabinets and machines for machine and plant construction.

It is rarely possible to allow for detailed concrete cable lengths in advance during the planning phase of a plant. When installing the plant, connectors that can be assembled on site out in the field are a great help in this regard, as cables can be adapted to fit. In spite of this, there is still a requirement for pre-assembled system cables in this environment. Users are looking to reduce the risk of errors, which can easily occur with untrained staff carrying out on-site assembly. This is where HARTING cable-to-cable housings come to the rescue, meeting both requirements. They make it possible to use ex-works pre-assembled and individually tested system cables and flexible cabling and cable length extensions on site. If an existing tested system cable that has been pre-assembled in the works is not enough for cabling the plant, the appropriate additional extension cable can be used to ensure that plant cabling is completed to requirements and using optimal lengths. This means that users obtain tested system cables ex works with a functional guarantee, but also the required freedom for on-site cabling.

For the transmission of Industrial Ethernet and power supply, cable-to-cable housings with the appropriate contact inserts can be fitted for the Han® PushPull family variant 4 (to IEC 61076-3-103) and 14 (to IEC 61076-3-1117). A bandwidth of up to 10 gigabits can be achieved with a reliable AWG 22-27 conductor cross section for the transmission of Industrial Ethernet. For power supply, using 5 contacts, up to 690 V and 16A can be carried with a reliable conductor cross section measuring up to 2.5 mm². In terms of connection technology, contact inserts, tool-free Insulation Displacement Connections, Han-Quick Lock® quick connection technology and tried and tested crimp connection technology are also available.
