SERCOS optical fiber
Fagor Automation supplies the fiber optic cables for SERCOS communi-
cations between the group of drives and the CNC in a ring connection and
in lengths ranging from 1 to 100 meters. The cables between drives come
with the connectors for each module. For SERCOS connection
under 40
m
, use the fiber optic cable with polymer core.
Its sales references are:
SFO- cable
SFO-FLEX-
 cable

For SERCOS connection over 40 m, use the fiber optic cable with glass
core.
T. H7/16 Range of SFO- cables. The number indicates their length in
meters.
SFO-1 SFO-2 SFO-3 SFO-5 SFO-7 SFO-10 SFO-12
T. H7/17 Range of SFO-FLEX- cables. The number indicates their length
in meters.
SFO-FLEX-10 SFO-FLEX-20 SFO-FLEX-30 SFO-FLEX-40
SFO-FLEX-15 SFO-FLEX-25 SFO-FLEX-35
INFORMATION. The max. length for fiber optic cables of the references
mentioned earlier for best performance is 40 meters.

T. H7/18 Mechanical characteristics of the SFO- cable.
Flexibility
Normal. It must only be used in systems under static con-
ditions where the minimum bending radius is 30 mm.
Use only in static conditions!
Covering
PUR. Polyurethane resistant to chemical agents used in
machine-tools.
Temperature
Work: - 20°C to + 80°C (- 4°F to 176°F)
Storage: - 35°C to + 85°C (- 31°F to 185°F)
T. H7/19 Mechanical characteristics of the SFO-FLEX- cable.
Flexibility
High. Special for cable-carrying chains with a minimum
bending radius, in dynamic conditions, is 70 mm.
Use only in dynamic conditions!
Covering
PUR. Polyurethane resistant to chemical agents used in
machine-tools.
Temperature
Work: - 20°C to +70°C (- 4°F to 158°F)
Storage: - 40°C to +80°C (- 40°F to 176°F)
INFORMATION. The SFO-FLEX- fiber optic cables are compatible with
the SFO-
 cables. The SFO-FLEX- are more flexible.
i
NOTE. If the fiber optic cable for SERCOS communication between
modules is going to be moving (dynamic conditions),
always use the
SFO-FLEX-
 cable. The SFO- cable will be enough for static condi-
tions (resting). The useful life span of a SFO-
 cable cannot be guaran-
teed if it is installed in applications where it works under dynamic
conditions (moving).
