Wire/Cable Types
Analog Signal and Encoder
Cable
Always use shielded cable with copper wire. Wire with insulation rating of
300V or greater is recommended. Analog signal wires should be separated
from power wires by at least 0.3 meters (1 foot). It is recommended that
encoder cables be run in a separate conduit. If signal cables must cross
power cables, cross at right angles. Terminate the shield of the shielded
cable as recommended by manufacturer of the encoder or analog signal
device.

Communications
DeviceNet
DeviceNet cable options, topology, distances allowed and techniques used
are very specific to the DeviceNet network. Refer to
DeviceNet Cable
System Planning and Installation Manual
, publication DN-6.72.
In general, there are 4 acceptable cable types for DeviceNet media. These
include:
1.
Round (Thick) cable with an outside diameter of 12.2 mm (0.48 in)
normally used for trunk lines but can also be used for drop lines
2.
Round (Thin) cable with an outside diameter of 6.9 mm (0.27 in)
normally used for drop lines but may also be used for trunk lines
3.
Flat cable normally used for trunk lines
4.
KwikLink drop cable used only in KwikLink systems.

If the wires are short and contained within a cabinet which has no sensitive circuits, the use of shielded wire may
not be necessary, but is always recommended.
