1 Safety information
1.1 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 sunlight
or other weather influences, unless this is expressly permitted in the operating
instructions.
■These operating instructions contain information required during the life cycle of
the sensor.
1.2 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
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
When mounting multiple through-beam photoelectric sensors next each other, swap
the arrangement of the sender (WS26) and receiver (WE26) for every second pair.
Also maintain a sufficiently large distance between the pairs based on the light spot
diameter of the sender (WS26), see figure 1.

Note the sensor’s maximum permissible tightening torque of < 1,3 Nm.
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 supply/switch on the voltage once all electrical connections have been estab‐
lished.

6 Additional functions
Alarm
Alarm output: The sensor (WSE26) features a pre-failure notification output (“Alarm”
in the connection diagram [see table 3]), 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 (WSE26) features a pre-failure notification output (“Health”
in the connection diagram [see table 3]), 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 sensors (WSO26P, WSO26I) feature a test input (“TI” or “Test” on the
connection diagram [see table 2]), 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 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]).
The send LED is shut down or the detection of an object is simulated. Refer to table 7
to check the function. If the switching output fails to behave in accordance with the
graphic, check the application conditions, see "Troubleshooting", page 12.

7 Commissioning
7.1 Alignment
WSO26P: 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 table]. You must ensure that the optical openings (front screen) of the sensors are
completely clear.
ADDITIONAL FUNCTIONS 6

Subject to change without notice 9

WSO26I: 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 LEDs.
See table and 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.

7.2 Check the application conditions
WSE26 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.
Note application conditions: Adjust distance between sender and receiver with the
associated diagram [see table 8] (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].
NOTE TIP:
For some applications (e.g., when switching errors arise due to reflections), we recom‐
mend slightly misaligning the sender and receiver or significantly reducing the oper‐
ating reserve. The WSE26 can suppress switching errors under these conditions by
means of a teach-in (via IO-Link or using the Teach-in button on the housing). This
reduces the operating reserve at the same time.

2. Short-circuit
1. Adjustment of the configura‐
tion
2. Check electrical connections

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 correspondingly.

(WS) and receiver (WE) is too
large / Beam of WS is not
completely on WE or WE is not

an object is in the path of the
beam.
The beam of light of a pho‐
toelectric through-beam sen‐
sor hits the receiver of
another (neighboring) photo‐
electric through-beam sensor

ond through-beam photoelec‐
tric sensor and ensure that
there is sufficient distance
between the through-beam
photoelectric sensors
10 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).
NOTE
Disposal of batteries, electric and electronic devices
•According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
•The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
WEEE: This symbol on the product, its package or in this document,
indicates that a product is subject to these regulations.
11 Maintenance
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•Clean the external lens surfaces
