4 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of accesso‐
ries).
Note the sensor's maximum permissible tightening torque of 2 Nm.
Note the preferred direction of the object relative to the sensor, cf. figure 1.
5 Electrical installation
The sensors must be connected in a voltage-free state (UV = 0 V). The following informa‐
tion must be observed, depending on the connection type:
– Plug connection: note pin assignment: when the lid is open, the male connector
can be swiveled horizontally and vertically.
– Terminal connection: Note the permissible cable diameter of 5 to 10 mm. When
the lid is open, the M16 connector can be swiveled horizontally and vertically.
Unscrew the M16 connector and remove sealing plug. Lead voltage-free supply
cable through and connect sensor in accordance with table 2 table 6. Retighten
M16 connector with seal so that the IP enclosure rating of the device is ensured.

1Alignment
WT24-2Xx4x, -2Xx5x: align sensor on object. Select the position so that the red emitted
light beam hits the center of the object. You must ensure that the optical opening (front
screen) of the sensor is completely clear [see figure 4].
WT24-2Xx1x, -2Xx2x: align sensor on object. Select the position so that the infrared light
(not visible) hits the center of the object. The correct alignment can only be detected via
the LED indicators. See figure 4 and table 3 and table 7. You must ensure that the optical
opening (front screen) of the sensor is completely clear.
Figure 4: Alignment Figure 5: Alignment 2
2Sensing range
Check the application conditions: Adjust the sensing range and distance to the object or
background and the remission capability of the object according to the corresponding dia‐
gram [see figure 6 and figure 7] (x = sensing range, y = transition range between the set
sensing range and suppression of the background as a % of the sensing range (object
remission/background remission)). Remission: 6% = black 1, 18% = gray 2, 90% = white
3 (referring to standard white as per DIN 5033). We recommend making the adjustments
using an object with a low remission.
6 COMMISSIONING

Subject to change without notice

The minimum distance (= y) for background suppression can be determined from diagram
[ figure 6 1] as follows:
Example: x = 600 mm, y = 4.5 => 4.5% of 600 mm = 27 mm. That is, the background is
suppressed at a distance of > mm from the sensor.

3Sensing range setting
Sensor with potentiometer: open the sensor cover and protective hood, make sure that no
dirt has gotten into the sensor.
The sensing range is adjusted with the potentiometer (type: without stop ). Clockwise rota‐
tion: sensing range increased; counterclockwise rotation: sensing range reduced. We rec‐
ommend placing the object within the sensing range, e.g. see table 9. Once the sensing
range has been adjusted, the object is removed from the path of the beam, which causes
the background to be suppressed and the switching output to change [see table 3 and
table 7].
Table 9: Sensing range setting
COMMISSIONING 6
8008784.Z474 | SICK
Subject to change without notice 11

For WT24-2B470 (with foreground suppression): The sensing range is adjusted relative to
the background with the potentiometer. Clockwise rotation: sensing range increased; coun‐
terclockwise rotation: sensing range reduced. Turn the potentiometer clockwise until the
yellow LED indicator lights up. Afterwards, only turn the potentiometer counterclockwise as
far as is needed so that the yellow LED no longer lights up. When an object is moved into
the path of the beam, the yellow LED indicator must light up. If the yellow LED indicator
does not light up during object detection, repeat the adjustment process, or reduce the dis‐
tance between the sensor and background and then repeat the adjustment process.
The sensor is adjusted and ready for operation.
4Time function setting
WT24-2xx2x, WT24-2xx5x: no time delay, t1 = time delay, t2 = time delay; for -2R: 0 = relay
deactivated, 1 = relay active. Time delay selector switch can be set on the device according
to see table 1.

8 Troubleshooting
The Troubleshooting table indicates which measures are to be taken if the sensor stops
working.
Table 10: Troubleshooting
LED indicator/fault pattern Cause Measures
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
Sensor is faulty If the power supply is OK,
replace the sensor
Object in beam path, no output
signal
Test input (Test) is not con‐
nected properly
Check connection of the test
input. When using female
cable connectors with LED
indicators, make sure the test
input is assigned correspond‐
ingly.
Yellow LED flashes; if Alarm is
present then take note of the
corresponding output signal
Sensor is still ready for opera‐
tion, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the beam of
light (light spot) with the
object / Clean the optical sur‐
faces / Check sensing range
and adjust if necessary, see
Figures 6-8 and table 8.
Yellow LED lights up, no object
in the path of the beam

too large
Reduce the sensing range,

Object is in the path of the
beam, yellow LED does not

Distance between the sensor
and the object is too long or

9 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
10 Maintenance
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•Clean the external lens surfaces
•Check the screw connections and plug-in connections
No modifications may be made to devices.

15 Montage
Den Sensor an einen geeigneten Befestigungswinkel montieren (siehe SICK-Zubehör-
Programm).
Maximal zulässiges Anzugsdrehmoment des Sensors von 2 Nm beachten.
Vorzugsrichtung des Objektes zum Sensor beachten, vgl. Abbildung 10.
16 Elektrische Installation
Anschluss der Sensoren muss spannungsfrei (UV = 0 V) erfolgen. Je nach Anschlussart
sind die folgenden Informationen zu beachten:
