1 General safety notes
■Read the operating instructions before commissioning.
■
Connection, mounting, and configuration may only be performed by trained
specialists.
■
2006/42/EC
NO
SAFETY
Not a safety component in accordance with the EU Machinery Directive.
■
Do not install the sensor at locations that are exposed to direct UV radiation
(sunlight) or other weather influences, unless this is expressly permitted in the
operating instructions.
■When commissioning, protect the device from moisture and contamination.
■These operating instructions contain information required during the life cycle of

2 Notes on UL approval
The device shall be supplied from an isolating transformer having a secondary overcur‐
rent protective device that complies with UL 248 to be installed in the field rated either:
a) max 5 amps for voltages 0 ~ 20 V (0 ~ 28.3 V peak), or
b) 100 / Vp for voltages of 20 ~ 30 V (28.3 ~ 42.4 V peak).
Alternatively, they can be supplied from a Class 2 power supply.
UL Environmental Rating: Enclosure type 1
3 Product description
3.1 Intended use
The WSE4F 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 product is
used for any other purpose or modified in any way, any warranty claim against SICK AG
shall become void.

4 Mounting
Mount sensors (sender and receiver) using suitable mounting brackets (see the SICK
range of accessories). Align the sender and receiver with each other.
NOTE
When mounting multiple through-beam photoelectric sensors next each other, swap
the arrangement of the sender (WSO4F) and receiver (WEO4F) for every second pair.
Also maintain a sufficiently large distance between the pairs based on the light spot
diameter of the sender (WSO4F). See figure 1 and figure 2.

The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Pin assignment
– Cable: Wire color
Only apply voltage/switch on the voltage supply once all electrical connections have
been established.
Operation in IO-Link mode: Connect the device to a suitable IO-Link master and inte‐
grate in the master or control via IODD/function block. The green LED flashes on the
sensor. IODD and function block are available to download from www.sick.com under
the part number.

6 Additional functions
Alarm: Operation with borderline light reception
Alarm output: The sensor (WSE4F) features a pre-failure notification output (“Alarm”
in the connection diagram), which issues a notification if the sensor is only ready for
operation to a limited extent. The LED flashes in this case. Possible causes: Sensor
is contaminated, sensor is out of alignment. In the good state: LOW (0), if excessively
contaminated HIGH (1).
Health
Health output: The sensor (WSE4F) features a pre-failure notification output (“Health”
in the connection diagram), which issues a notification if the sensor is only ready for
operation to a limited extent or the cable has been interrupted. Possible causes: Sensor

is contaminated, sensor is out of alignment, cable is damaged. In the good state: HIGH
(1), if excessively contaminated or in the event of cable interruption LOW (0). The yellow
LED indicator flashes in this case.

Test input
Test input: The WSE4F sensors feature a test input (“Test” on the connection diagram
[see table 2, page 7]), which can be used to switch the sender off and, therefore, 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.
It is important that there is no object between the sender and receiver, activate the test
input (see the connection diagram [see table 2, page 7]).
The send LED is shut down or the detection of an object is simulated. Refer to table 8
to check the function. If the switching output fails to behave in accordance with the
following table, check the application conditions, see "Troubleshooting", page 12.

7 Commissioning
7.1 Alignment
WSO4FP: Align the sender (WSO4F) with the receiver (WEO4F). 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 beam [see figure 3]. You must ensure that the optical openings (front
screen) of the sensors are completely clear.

WSO4FI: Align the sender (WSO4F) with the receiver (WEO4F). Select the position so
that the infrared light (not visible) hits the receiver. The correct alignment can only be
detected via the LEDs. See figure 3 and table 6. The sender must have a clear view of
the receiver, with no object in the path of the beam. You must ensure that the optical
openings (front screen) of the sensors are completely clear.

7.2 Check the application conditions:
Sensing range
WSE4F are through-beam photoelectric sensors that can be used at shorter distances,
in particular due to the large sensing range or the very high operating reserve.
Observe the application conditions: Adjust the distance between the sender and the
receiver according to the corresponding diagram [see figure 6 and see figure 5,
page 11] (x = sensing range, y = operating reserve).
If several through-beam photoelectric sensors which are installed next to one another
are to be used, we recommend swapping the sender/receiver arrangement at every
second through-beam photoelectric sensor and ensuring that there is sufficient dis‐
tance between the through-beam photoelectric sensors. By doing this, mutual interfer‐
ence can be prevented [see figure 1].
Check the function as described in table 6. If the switching output fails to behave as
described in table 6, check the application conditions.
