Product Description
The LD32 sensor family is
available in a compact 12 x
32 x 20 mm reinforced
PMMA/ABS-housing.
The sensors are useful in
applications where high-
accuracy detection as well as
small size is required.
The Teach-In function for
adjustment of the sensitivity
makes the sensors highly
flexible.
The small spot and back-
ground suppression makes
the sensor able to detect
small objects close to the
background.
The output type is preset
(NPN or PNP), and the output
switching function is pro-
grammable (NO or NC).

Installation Hints
To avoid interference from inductive voltage/
current peaks, separate the prox. switch pow-
er cables from any other power cables, e.g.
motor, contactor or solenoid cables
Relief of cable strain
Protection of the sensing face
Switch mounted on mobile carrier
Incorrect
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided

Adjustment
Sensitivity adjustment, with static object
1.
Line up the sensor with the object. Yellow LED and
green LED are ON.
2.
Press the button for 3 s until both LED’s flash
simultaneously (the first switching point is stored).
3.
Place the object outside the detection area.
4.
Press the button for 1 s.
a)
The green LED flashes and stays ON: the
second switching point is stored, and the sensor
is ready to operate.
b)
Both LED’s flash simultaneously: the sensor
cannot detect the object, no switching points
are stored.

Programming of make and break switching function
13 s
1.
Press the button for 13 s.
Both LED’s flash alternately.
2.
Release the button: the green LED flashes.
3.
While the green LED flashes, the output is inverted
each time the button is pressed. This is indicated by
the yellow LED.
When the button is not pressed for 10 s, the current
output function is stored.
The sensor is now ready for operation.
Default setting
1.
No object in the detection area: Press the button for
3 s, until both LED’s flash simultaneously.
3s
2.
No object in the detection area:
1s
Press the button for 1 s.
The sensor is set to maximum sensitivity.
NB!
The Teach Input (2 WH) will work similarly to the push
button, active High.
3s
1s
Sensitivity adjustment, with only one object
1.
Line up the sensor with the object. Yellow LED and
green LED are ON.
2.
Press the button for 3 s until both LED’s flash
simultaneously (the first switching point is stored).
3.
Leave the object in the detection area, press the
button for 1 s. The green LED flashes and stays on:
the second switching point is stored, and the sensor is
ready to operate.
Sensitivity adjustment, with a running process
1.
Line up the sensor with the object. Green LED is ON.
At this stage the status of the yellow LED can be
ignored.
2.
The running process must be the only “object” within
the detection area. Press the button for 3 s until both
LED’s flash simultaneously.
3s
3.
Press the button for at least the duration of one pro-
cess cycle.
1 cycle
a)
b)
The green LED flashes and stays ON: both
switching points have been stored, and the sen-
sor is ready to operate.
Both LED’s flash simultaneously: the sensor
cannot detect the object, no switching points
are stored.
