OUTPUT LED
The yellow LED ON indicates that the NO output is closed.
DISPLAY (green-coloured display)
The display indicates the value of the measurement detected [operating mode function].
Please refer to the following paragraphs for the correct indications to follow during the acquisition or
setting phase.
M1, M2 LEDs
The LED couple visualises the operating mode according to the table given below:

ALARM LED
The blinking of the alarm LED indicates that the received signal is insufficient for the correct sensor
functioning. In this case the “digital alarm” output is activated.
SET PUSH-BUTTON
Pressing the push-button for at least 2 seconds activates the self-setting procedure (2 thresholds =>
2 phases).
A long pressure on the button (at least 6 seconds) allows the user to access into the sensor
parameter setting menu.
Please refer to the following paragraphs for the correct indications to follow during the parameter
setting phase.
+/- PUSH-BUTTONS
Pressing the + or – push-buttons for at least 2 seconds allows the user to access into the manual
adjustment mode of the 2 switching thresholds.
The contemporary pressure on the + and – push-buttons (at least 2 seconds) activates the
acquisition procedure of the working area map.
The contemporary pressure on the + and – push-buttons (at least 6 seconds) activates the setting
procedure of the reflecting tape characteristics.
Please refer to the following paragraphs for the correct indications to follow during functioning.
INSTALLATION
The sensor can be mounted by means of the three housing’s holes
using two screws (M4x35 or longer) with washers.
Various orientable fixing brackets to ease the sensor positioning
are available (please refer to the accessories listed in the
catalogue).
The operating distance is measured from the front surface of the
sensor optics.
The M12 connector can be oriented at three different positions
using the specific fastening spring and rotating the block of 180°.

FUNCTIONING
The S65-PA-5-Z sensor is a line sensor.
The typical functioning diagram is shown in the drawing given below. The object to detect is placed in
front of the sensor and the reflecting tape (inside the package) behind the sensor. The sensor
illuminated with IR lights the tape and receives the reflected light on a photodiode array. Each object
placed between the reflecting tape and the sensor is naturally detected as a dark spot on a luminous
background.
The sensor has 5 operating modes:
•
Object beg.
: the position of the first object edge is detected
•
Object end
: the position of the second object edge is detected
•
Object centre
: the centre of the object is measured
•
Width
: the distance between the first and last object edge is measured
•
Area
: the sum of all the object obscured zones is measured
The following diagram shows the sensor output according to the possible object position inside the
meaurement zone.

APPLICATION NOTES
The drawing shows how the same object can generate
different obscured zones if placed in different positions
inside the sensor working zone. The same happens if
the object is placed at different distances.
The “Area” operating mode is particularly sensitve to the
reflecting tape’s characteristics and for this reason the
sensor can detect the main specifications of the tape
used (please refer to “Advanced functions” paragraph”).
