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 WLA26 is an opto-electronic photoelectric retro-reflective sensor (referred to as
“sensor” in the following) for the optical, non-contact detection of objects, animals, and
persons. A reflector is required for it to function. If the product is used for any other
purpose or modified in any way, any warranty claim against SICK AG shall become void.

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‐

6 Additional functions
Alarm
Alarm output: The sensor (WLA26) features a pre-failure notification output (“Alarm” in
the connection diagram [see table 2]), 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 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 (WLA26) features a pre-failure notification output (“Health”
in the connection diagram [see table 2]), 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 or reflector is contaminated, sensor is out of alignment, cable is dam‐
aged. 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 WLA26 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 sensor and reflector; 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 6
to check the function. If the switching output fails to behave in accordance with the
graphic, check the application conditions, see "Troubleshooting", page 13.

7 Commissioning
7.1 Alignment
Align the sensor with a suitable reflector. Select the position so that the red emitted
light beam hits the center of the reflector. The sensor must have a clear view of the
reflector, with no object in the path of the beam [see figure 1]. You must ensure that the
optical openings of the sensor and reflector are completely clear.

7.2 Check the application conditions
WLA26 are photoelectric retro-reflective sensors in which the autocollimation principle
has been combined with a multi-receiver element, thereby ensuring the greatest possi‐
ble resistance to depolarizing objects combined with a very high sensing range. This
means the WLA26 has a high operating reserve (insensitivity to dust) and does not
exhibit any switching errors with depolarizing objects.
Adjust the distance between the sensor and the reflector according to the correspond‐
ing diagram [see table 7] (x = sensing range, y = operating reserve).
NOTE TIP:
Should switching errors nevertheless arise due to extremely depolarizing objects, the
WLA26 can also be adapted to these extreme conditions and the switching errors
suppressed by means of a teach-in (via IO-Link or using the Teach-in button on the
housing).

7.3 Sensing range setting
WLA26x-xxxxxx3xAxx with teach-in button:
There must not be any objects located between the WLA26 and the reflector. The
sensitivity is reduced by pressing the teach-in button (approx. 1-3 sec.). This primarily
suppresses false switching to extremely depolarizing objects. The sensing range is also
reduced, and therefore the operating reserve as well. Lead an object into the path of
the beam. The yellow LED goes out, meaning the object is detected and the setting is
correct.
