Torsion cable 6XV1 8300FH10
The torsion cable 6XV1 830-0PH10 corresponds to the specification IEC 61158-2 /
EN 61158-2, cable type A, with stranded copper cores (approximately AWG 24 19/36) with
the exception of the higher d.c.loop resistance.
This difference means a reduced segment length; refer to the table in Section "
Network
configuration (Page
41)".
In contrast to the standard bus cable, the cores of the torsion cable are of stranded copper.
In conjunction with the special combination of braid shield, foil shield, fleece layer and the
jacket material of polyurethane, the cable has a torsional strength of ±180° while retaining
highly constant electrical characteristics. The cable has been tested to a minimum of 5
million torsional movements on 1 m cable length (±180°).
If screw terminals are used, the stranded cores must be fitted with wireend ferrules (0.25
mm
2
complying with DIN 46228).
The cable is not suitable for use of the FastConnect (FC) stripping tool.
6ES7 972-0BA30-0XA0 bus connectors cannot be connected.
Properties
The characteristics of the flexible cable differ from those of the standard bus cable as
follows:
● The jacket material is free of halogens (polyurethane, PUR)
● Extremely good resistance to abrasion
● Resistance to mineral oils and fats
● Extremely good resistance to UV radiation
● Small bending radii for installation and operation
● Due to the smaller copper crosssection, the d.c. loop resistance and the HF attenuation
are higher which means reduced segment lengths.
● The jacket material is flame resistant
Use
The flexible cable is designed for torsion of ±180° and is therefore particularly suitable for
networking moving plant parts, for example robots.
Note
If you connect to screw terminals, the stranded cores must be fitted with wireend ferrules
(0.25 mm2 complying with DIN 46228). Use only wireend ferrules made of materials with
permanently stable contact properties, for example copper with a tinplated surface (not
aluminum).
