Sensor Cable, Optical Fiber
Sensor and controller are connected through an optical fiber.
-
Do not shorten or lengthen the optical fibers.
-
Do not pull or hold the sensor on the optical fiber.
-
The optical fibers has a diameter of 50 µm.
Do not soil the connectors, because this would lead to particle deposition in the control-
ler and therefore to strong loss of light. Cleaning of the connectors requires the corre-
sponding know-how and a fiber microscope for control.
Basic Rules
Avoid
-
any contamination of the connector, e. g. dust or finger prints, and frequent connect-
ing and disconnecting
-
any mechanical stress of the fiber (kinking, squeezing, pulling, twisting, knotting etc.)
-
strong bending of the fiber. as the optical fiber is damaged thereby rapidly and this
leads to permanent damage through micro-cracks
Please never underrun the allowed bending radius.
R
Fixed:
R = 30 mm or more
Flexible:
R = 40 mm or more
Do not kink the sensor cable.
Please do not grind the sensor cable
over sharp corners.
Do neither squeeze the sensor cable nor
fix it by using cable ties.
Do not pull the sensor cable.
Miniature sensors IFS2402, hybrid sensors IFS2403
The optical fibers are fixed to the sensor and cannot be replaced. Repairs involve reduc-
ing the cable length and a new connector through the manufacturer only.
Standard sensors IFS2405
The
sensor cable is connected to the sensor. Sensor cables may be up to 50 m long.
Cables for drag chain use and cables with protective metal tubing are available, see
. A damaged sensor cable can be replaced, see Chap.
