CAN cable
Screened twisted-pair cables (2x2) with a characteristic impedance of between 108 and 132 Ohm is recom-
mended for the CAN wiring. If the CAN transceiver’s reference potential (CAN ground) is not to be connected,
the second pair of conductors can be omitted. (This is only recommended for networks of small physical size
with a common power supply for all the participating devices).
ZB5100 CAN Cable
A high quality CAN cable with the following properties is included in Beckhoff's range:
· 2 x 2 x 0.25 mm² (AWG 24) twisted pairs, cable colours: red/black + white/black
· double screened
· braided screen with filler strand (can be attached directly to pin 3 of the 5-pin connection terminal),
· flexible (minimum bending radius 35 mm when bent once, 70 mm for repeated bending)
· characteristic impedance (60 kHz): 120 Ohm
· conductor resistance < 80 Ohm/km
· sheath: grey PVC, external diameter 7.3 +/- 0.4 mm
· Weight: 64 kg/km.
· printed with "BECKHOFF ZB5100 CAN-BUS 2x2x0.25" and metre marking (length data every 20cm)
ZB5200 CAN/DeviceNet Cable
The ZB5200 cable material corresponds to the DeviceNet specification, and is also suitable for CANopen sys-
tems. The ready-made ZK1052-xxxx-xxxx bus cables for the Fieldbus Box modules are made from this cable
material. It has the following specification:
· 2 x 2 x 0.34 mm² (AWG 22) twisted pairs
· double screened braided screen with filler strand
· characteristic impedance (1 MHz): 126 Ohm
· conductor resistance 54 Ohm/km
· sheath: grey PVC, external diameter 7.3 mm
· printed with "InterlinkBT DeviceNet Type 572" as well as UL and CSA ratings
· stranded wire colours correspond to the DeviceNet specification
· UL recognised AWM Type 2476 rating
· CSA AWM I/II A/B 80°C 300V FT1
