11.9 CAN bus cable
According to ISO 11898 you should use a bus cable with a characteristic impedance of
120Ω. The usable cable length depends on the transmission rate. The values that we have
measured can be taken as a guide, but they should not be interpreted as limits:
Cable data
l
Characteristic impedance: 100-120 Ω
l Cable capacitance: max. 60 nF/km
l
Conductor (loop) resistance:159.8 Ω/km
Cable length, depending on the transmission rate:
Transmission rate / kbps 1000 500 250
max. cable length / m 20 70 115
The table refers to the total cable length between the ends of the bus. Longer transmission
distances can be achieved with a lower cable capacitance (max. 30nF/km) and lower loop
resistance (115 Ω/km).
11.9.1 CAN bus cable AKD
We deliver configured CAN bus cables for
AKD-xyyyzz-xxCN and AKD-xyyyzz-xxCC.
Article Length AKD Order code
CAN Bus cable 0.15 m CBP000-002-m15-00
CAN Bus cable 0.30 m CBP000-002-m30-00
CAN Bus cable 1.00 m CBP000-002-001-00
CAN Bus cable 3.00 m CBP000-002-003-00
The CAN Termination connector is required for bus termination of the last AKDconnected to
the CAN bus. For connecting an AKD to a CAN device with SubD9 connector the CAN
RJ12-SubD9 Adapter can be used.

11.9.2 Can bus cable for S300/S400/S600/S700
We do not deliver configured cables for S300/S400/S600/S700.
Usage of the materials in the table below ensure that all the requirements are met.
Part Designation Order code
Cable Li2YCY (TP) 2x2x0.25mm² DE-86834 (cut to length)
SubD kit 9-pin SubD connector (socket) DE-90650
If your cable has more connectors than you need, any of them can be left free.
For EMC reasons, the SubD connector housings must fulfil the following conditions:
l metal or metallic-coated housing
l provision for connecting the cable shielding to the housing, large-area connection
