Fiber Optic Sensors
Fiber optic sensors function electronically like any other photoelectric sensor with the difference that the light emitted and received is transported by an optical fiber the end of which is very small and in different forms and it can be installed some distance from the electronic circuit.
The reduced dimension of the fiber allows the sensing of very small objects and their installation in areas where other sensors would not fit.
Furthermore they can be used in explosion risk areas as well as in liquids and have a very high resistance to mechanical damage and to vibrations which makes them suitable for installation on machinery were movement is involved.
They are available in the reflection and barrier emitter/ receiver.
The light source is red and the length of the standard fibers is 2 meters.

FT18M-CFR WITH FIBERS FOR DIRECT REFLECTION In this type of function the red light emitter and receiver are contained in one fiber (MULTI CORED) or side by side (DOUBLE CORED). The sensing is obtained by the reflection of the rays of the object to be detected. The parameters that influence the sensing distance are mainly the color, the reflective or the roughness of the surface to be sensed. The maximum sensing distances mentioned in the technical characteristics refer to results obtained with a piece of matt white paper dimension 10 x 10 cm. |

 |
FT18M-CFR WITH BARRIER FIBERS EMITTER/RECEIVER In this type of function the red light emitter and receiver are facing each other and are made up of a single fiber (SINGLE CORED). Detection occurs when the rays emitted are interrupted furthermore these fibers can reach at their maximum sensitivity regulation, long distances as there is no dispersion between emitter and receiver. Their power can be increased by using the AT-4101 lenses. |

1 TRIMMER FOR THE SENSING RANGE ADJUSTMENT: The photocell is supplied with max. sensing range with the trimmer totally rotated in the clockwise direction. The sensitivity reduces by rotating the trimmer in the anti-clockwise direction. |
| 2 SWITCH NPN/PNP: The photocell is supplied with the switch in P (PNP output). To change to NPN turn the switch to N in the anti-clockwise direction. WARNING! For a correct working of the unit, do not carry out the switching when the photocell is powered. | |
| 3 GREEN LED - STABILITY INDICATOR: This led is on when the level of the output signal and the alignment of the photoelectric sensors are in the optimum position. In the case that the led is off this indicates that the lens is obscured or for the types with direct reflection a possible alteration of the dimension or color of the object to be detected. | |
| 4 YELLOW LED - OPERATION INDICATOR: This led is on when the object to be detected enters the sensing range of the photocell giving output signals. | |
| N.B. SENSITIVITY ADJUSTMENT | |
| • After adjustment the sensitivity can vary depending on variations in the object or conditions in the area of installation. | |
| • As reflection varies in relation to the object, adjustment should be carried out with the object present. | |
| • After having carried out adjustment, the fixing of the way and the curvature of the fiber should not be changed. | |
| PROCEDURE FOR THE DIRECT REFLECTION FIBER OPTICS ADJUSTMENT: | PROCEDURE FOR THE THRU-BEAM FIBER OPTICS ADJUSTMENT: |
| Adjust the sensitivity to minimum turning the trimmer anticlockwise. Position the object to be sensed at the required distance in relation to the end of the fiber and turn the trimmer slowly clockwise until the yellow led lights up. Continue turning the trimmer until the green led lights up. Recheck that the calibration is correct by using the object and possibly by repeating the procedure. | Adjust the sensitivity to minimum turning the trimmer anticlockwise.

FIBER PROBES
Cutting-free type plastic fibers can be cut by the optional cutter (AT118) at any desired length
Cut the plastic fiber before connection. Make sure to cut it sharply since the status of cutting surface influences to the sensing distance which might be reduced by up to 20%.
Cutting should be done sharply by one action, and do not use the same hole more than once.
FIBER FIXING
Use the supplied spring lockwasher for fixing the fibers with threaded bushing in order not do damage the fibers with excessive force.
When fixing the non-threaded head type with a set-screw (M3 max.) as indicated on the left side scheme, apply a torque of 3 kgf/cm max.
CONNECTION OF DIRECT REFLECTION MULTI-CORED FIBER
Put the SINGLE-CORED fiber to the LIGHT-EMITTER side and the MULTICORED fiber to the RECEIVER side.
STAINLESS SLEEVE FIBERS
The fibers with this type of terminal are very useful when the installation is done in locations not easily accessible and this can be obtained bending the sleeve in relation to the required position.
Make the bending radius to be processed on anneals stainless sleeve on the sensing head as large as possible according to the sleeve diameter rate as indicated on the left side scheme.
