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
the sensor.
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 Intended use
The WLD4F 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 Mounting
Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
Note the sensor’s maximum permissible tightening torque of < 0,4 Nm.
6 Electrical installation
Operation in standard I/O mode:
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.

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:
Sensing range
Adjust the distance between the sensor and the reflector according to the correspond‐
ing diagram [figure 3] (x = sensing range, y = operating reserve).
After alignment, place a non-transparent object into the path of the beam. Check the
function as described in figure X. If the switching output fails to behave as described in
figure X, check the application conditions.

16 Montage
Sensor und Reflektor an geeignete Befestigungswinkel montieren (siehe SICK-Zube‐
hör-Programm). Sensor und Reflektor zueinander ausrichten.
Maximal zulässiges Anzugsdrehmoment des Sensors von < 0,4 Nm beachten.
17 Elektrische Installation
Betrieb im Standard-I/O-Modus:
Anschluss der Sensoren muss spannungsfrei erfolgen. Je nach Anschlussart sind die
folgenden Informationen zu beachten:
– Steckeranschluss: Pinbelegung
– Leitung: Adernfarbe
Erst nach Anschluss aller elektrischen Verbindungen die Spannungsversorgung anlegen
bzw. einschalten.
Betrieb im IO-Link-Modus: Gerät an geeigneten IO-Link-Master anschließen und per
IODD / Funktionsblock im Master, bzw. in der Steuerung integrieren. Am Sensor blinkt
die grüne Anzeige-LED. IODD und Funktionsblock stehen unter www.sick.com unter der
Bestellnummer zum Download bereit.
