Operating instructions
1 Safety notes
■Read the operating instructions before commissioning.
■Connection, mounting, and setting may only be performed by trained specialists.
■Not a safety component in accordance with the EU Machinery Directive.
■UL: Only for use in applications in accordance with NFPA 79. Adapters listed by UL
with connection cables are available. Enclosure type 1.
■When commissioning, protect the device from moisture and contamination.
■These operating instructions contain information required during the life cycle of
the sensor.
2 Correct use
The WSE9(M4)-3 is an opto-electronic through-beam photoelectric sensor (referred to
as "sensor" in the following) for the optical, non-contact detection of objects, animals,
and persons. A sender (WS) and a receiver (WE) are required for operation. If the pro‐
duct is used for any other purpose or modified in any way, any warranty claim against
SICK AG shall become void.
3 Commissioning
1 Observe the application conditions: Adjust the distance between the sender and
the receiver according to the corresponding diagram [H] (x = sensing range, y =
operating reserve).
If several through-beam photoelectric sensors which are installed next to one ano‐
ther are to be used, we recommend swapping the sender / receiver arrangement
at every second through-beam photoelectric sensor and ensuring that there is suf‐
ficient distance between the through-beam photoelectric sensors. By doing this,
mutual interference can be prevented [cf. F].

2 Mount sensors (sender and receiver) using suitable mounting brackets (see the
SICK range of accessories). Align the sender and receiver with each other.
Note the sensor's maximum permissible tightening torque of 0.6 Nm.
3 The sensors must be connected in a voltage-free state (VS = 0 V). The information
in the graphics [B] must be observed, depending on the type of connection:
– Male connector connection: pin assignment
– Cable: core color
Image: B
Only apply voltage / switch on the power supply (VS > 0 V) once all electrical con‐
nections have been completed. The green LED indicator lights up on the sensor.
Explanations of the connection diagram (graphic B):
Switching outputs Q and /Q (according to graphic B):
WSE9(M4)-3P (PNP: load -> M)
WSE9(M4)-3N (NPN: load -> L+)
TE / Test = test input (see Additional functions)
4 Align the sender with the receiver. Select the position so that the red emitted light
beam hits the receiver. Tip: Use white paper or a reflector as an alignment aid. The
sender must have a clear view of the receiver, with no object in the path of the be‐
am [see E]. You must ensure that the optical openings (front screen) of the sensors
are completely clear.

5 Additional functions
Test input: The WSE9(M4)-3 sensor features a test input ("TI" or "Test" on the connecti‐
on diagram [B]), which can be used to check that the sensor is functioning correctly: If
female cable connectors with LED indicators are used, you must ensure that the TI is
assigned accordingly.
There must be no object between the sender and receiver; activate the test input (see
the connection diagram [B], TI at 0 V). The send LED is shut down or the detection of an
object is simulated. Refer to Graphics C and G to check the function. If the switching
output fails to behave in accordance with Graphic C, check application conditions. See
section Fault diagnosis.

9 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regulati‐
ons. Efforts should be made during the disposal process to recycle the constituent ma‐
terials (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.

12 Bestimmungsgemäße Verwendung
Die WSE9(M4)-3 ist eine optoelektronische Einweg-Lichtschranke (im Folgenden Sen‐
sor genannt) und wird zum optischen, berührungslosen Erfassen von Sachen, Tieren
und Personen eingesetzt. Zum Betrieb ist ein Sender (WS) und ein Empfänger (WE) er‐
forderlich. Bei jeder anderen Verwendung und bei Veränderungen am Produkt verfällt
jeglicher Gewährleistungsanspruch gegenüber der SICK AG.
13 Inbetriebnahme
1 Einsatzbedingungen beachten: Distanz zwischen Sender und Empfänger mit dem
zugehörigen Diagramm [vgl. H] abgleichen (x = Schaltabstand, y = Funktionsreser‐
ve).
Beim Einsatz von mehreren Einweg-Lichtschranken, die nebeneinander installiert
werden, empfehlen wir, bei jeder zweiten Einweg-Lichtschranke die Anordnung von
Sender und Empfänger zu tauschen, bzw. genügend Abstand zwischen den Ein‐
weg-Lichtschranken einzuhalten. Damit können gegenseitige Beeinflussungen ver‐
mieden werden [vgl. F].

2 Sensoren (Sender und Empfänger) an geeignete Befestigungswinkel montieren
(siehe SICK-Zubehör-Programm). Sender und Empfänger zueinander ausrichten.
Maximal zulässiges Anzugsdrehmoment des Sensors von 0.6 Nm beachten.
3 Anschluss der Sensoren muss spannungsfrei (UV = 0 V) erfolgen. Je nach An‐
schlussart sind die Informationen in den Grafiken [vgl. B] zu beachten:
– Steckeranschluss: Pinbelegung
– Leitung: Adernfarbe
Abb.: B
Erst nach Anschluss aller elektrischen Verbindungen die Spannungsversorgung (UV
> 0 V) anlegen bzw. einschalten. Am Sensor leuchtet die grüne Anzeige-LED.

4 Sender auf Empfänger ausrichten. Positionierung so wählen, dass der rote Sende‐
lichtstrahl auf den Empfänger auftrifft. Tipp: weißes Papier oder Reflektor als Aus‐
richthilfe verwenden. Der Sender muss freie Sicht auf den Empfänger haben, es
darf sich kein Objekt im Strahlengang befinden [vgl. E]. Es ist darauf zu achten,
dass die optischen Öffnungen (Frontscheiben) der Sensoren vollständig frei sind.
