OMRON Thick Cables and Thin Cables are available in lengths of 100 m.
Consult with your OMRON representative for other cable lengths.
The following procedure shows how to wire using Special Thin/Thick Cable.
Refer to the DeviceNet Operation Manual (Cat. No. W267) for the procedure
for Flat Cable.
Use the following procedure to prepare and connect the communications
cables to the connectors.
1. Strip about 30 mm of the cable sheathing, being careful not to damage the
woven shield just below the sheathing. Do not remove more than about
30 mm; removing too much of the covering can result in short circuits or
allow noise into the Network.
Approx. 30 mm
2. Carefully peel back the woven shield. There is a bare shield wire under the
woven shield as well as the signal lines and power lines. (The shield wire
will be loose on the outside of the other lines, but it is stiffer than the woven
shield and easy to identify by touch.)
3. Cut away the exposed woven shield, remove the aluminum tape from the
signal and power lines, and strip the sheath from the signal and power lines
to the proper length for the crimp terminal connectors. Twist together the
stranded wires of each signal and power lines.
Strip proper length for
the terminals being used.
