2 Intended use
The WSE26 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
Swap the sender and receiver arrangement at every second through-beam photoelec‐
tric sensor and ensure that there is sufficient distance between the through-beam pho‐
toelectric sensors.

5 Electrical installation
The sensors must be connected in a voltage-free state. The following information must
be observed, depending on the connection type:
– Male connector connection: Note pin assignment
– Cable: wire color
Only apply voltage/switch on the power supply once all electrical connections have
been established.

6 Additional functions
Alarm
Alarm output: The sensor (WEO26 P, WEO26 I) features a pre-failure notification output
(“Alarm” in connection diagram [see table 6]), which issues a notification if the sensor
is only ready for operation to a limited extent. The LED indicator flashes in this case.
Possible causes: Sensor or reflector is contaminated, sensor is out of alignment. In the
good state: LOW (0), if excessively contaminated HIGH (1).
Health
Health output: The sensor (WEO26 P, WEO26 I) features a pre-failure notification output
(“Health” in connection diagram [see table 6]), which issues a notification if the sensor
is only ready for operation to a limited extent or the cable has been interrupted. Possi‐
ble causes: Sensor or reflector 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 sensors (WSO26 P, WSO26 I) feature a test input (“Test” in see table 2
and table 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 have to ensure that Test is assigned accordingly.
It is important that there is no object between the sender and receiver, activate the test
input (see the connection diagram [table 7]). The send LED is shut down or the detec‐
tion of an object is simulated. Refer to table 7 to check the function. If the switching
output fails to behave in accordance with table 7, check the application conditions. See
section Troubleshooting.

7 Commissioning
1Alignment
WSO26 P: 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 beam [see
figure 2]. You must ensure that the optical openings (front screen) of the sensors are com‐
pletely clear.
WSO26 I: Align the sender with the receiver. Select the position so that the infrared light
(not visible) hits the receiver. The correct alignment can only be detected via the LED indi‐
cators,see figure 2, figure 3 and see table 5. 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.

2Sensing range
Observe the application conditions: Adjust the distance between the sender and the
receiver according to the corresponding diagram [see figure 4] (x = sensing range, y = oper‐
ating 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 distance between
the through-beam photoelectric sensors. By doing this, mutual interference can be pre‐
vented [see figure 1].
