Push-pull cable-to-cable housings enable on-site installation flexibility

March 8, 2012
Harting's Han PushPull cable-to-cable housings enable flexible cabling options for energy, data and signaling transmission.

New from Harting, the Han PushPull cable-to-cable housings enable flexible cabling options for energy, data and signaling transmission. Specified to protection type IP65/67, the company says housings offer several advantages for device connection and the installation of switch cabinets and machines for machine and plant construction.

The company contends that, as 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 in the field are a great help, as cables can be adapted to fit. However, a requirement still exists for pre-assembled system cables in such environments, the better to reduce the risk of user errors, which can easily occur with untrained staff carrying out on-site assembly. Harting maintains that the Han PushPull cable-to-cable housings meet both requirements.

The company says the product makes it possible for installers to use "ex works" pre-assembled and individually tested system cables, and flexible cabling and cable length extensions, on an on-site basis. 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). Bandwidth of up to 10 gigabits can be achieved with a reliable AWG 22-27 conductor cross section for 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 mm sq.

Contact inserts and tool-free Insulation Displacement Connections are also available via the Harting's Han-Quick Lock quick connection and crimp connection technology.
