Connectable core cross-sections:
Solid conductors Options for PROFIBUS-DP connection:
2-core cable, shielded (bus cable)
Direct-buried cable
Flexible conductors
with wire end ferrule
without wire end ferrule
0.25 to 1.5 mm
2
0.25 to 2.5 mm

Number of cores per terminal connection 1 or combination of 2 cores up to 1.5 mm
2
(sum) in a common wire end ferrule
Permissible outside diameter of cable ∅ 4 to 10 mm
Bared length of cores (with or without
insulation collar)
6 mm
Bared length of cable sheath 45 mm
Wire end ferrules to DIN 46228
without insulation collar
with insulation collar
Form A up to 7 mm long
Form E up to 8 mm long
Bared Lengths: Example
The diagram below shows an example of bared lengths. These lengths apply to all
cables that are suitable for use with the connector assembly. Braided shields must
be twisted and inserted into wire end ferrules, and the projecting lengths cut off.
The shield around the PROFIBUS cores must be brought as close as possible to
the connectors.
