1 General safety notes
■Read these operating instructions before commissioning the device.
■
Connection, mounting and configuration of the device must only be carried
out by qualified personnel.
■
2006/42/EC
NO
SAFETY
This device does not constitute a safety component as defined in the
Machinery Directive.
■
When commissioning the device, ensure adequate protection against mois‐
ture, contamination and UV radiation (sunlight).
■These operating instructions contain information required during the life cycle of
the photoelectric 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 WTB4FP MultiSwitch is an opto-electronic photoelectric background suppression
proximity sensor (referred to as “sensor” in the following) for the optical, non-contact
detection of objects, animals, and persons. 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 using a suitable mounting bracket (see the SICK range of acces‐
sories).
Figure 1: Alignment of the sensor relative to the object direction
Note the sensor’s maximum permissible tightening torque of < 0,4 Nm.
Note the preferred direction of the object relative to the sensor, cf. see figure 1, page 6.
6 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: Pin assignment
– Cable: Wire color
Only apply voltage/switch on the voltage supply once all electrical connections have
been established.

7.1 Alignment
Alignment
Align the sensor with the object. Select the position so that the red emitted light beam
hits the center of the object. You must ensure that the optical opening (front screen) of
the sensor is completely clear [see figure 2].

7.2 Check the application conditions:
Sensing range
WTB4FP MultiSwitch are photoelectric proximity sensors with background suppression.
Depending on the remission of the object to be detected, and perhaps the background
behind it, a minimum distance (y) between the set sensing range (x) and the back‐
ground should be maintained.
Check the application conditions:
Adjust the sensing range and distance to the object or background as well as the
radiance capability of the object according to the corresponding diagram (x = sensing
range, y = minimum distance between set sensing range and background [white, 90%])
Radiance factor: 6% = black 1, 18% = gray 2, 90% = white 3 (referring to standard
white as per DIN 5033). We recommend that the adjustment be performed with an
object of low remission.
The minimum distance (= y) for the background suppression can be determined from
the diagram as follows:
Example: x = 100 mm, y = 4 mm. That is, the background (white, 90%) is suppressed at
a distance of > 4 mm from the sensor.

Ausrichtung
Sensor auf Objekt ausrichten. Positionierung so wählen, dass der rote Sendelichtstrahl
in der Mitte des Objekts auftrifft. Es ist darauf zu achten, dass die optische Öffnung
(Frontscheibe) des Sensors vollständig frei ist [siehe Abbildung 11].

18.2 Die Einsatzbedingungen prüfen:
Schaltabstand
WTB4FP MultiSwitch sind Reflexions-Lichttaster mit Hintergrundausblendung. Abhängig
von der Remission des zu detektierenden Objektes und des eventuell sich dahinter
befindlichen Hintergrundes, ist ein Mindestabstand (y) zwischen eingestelltem Schalt‐
abstand (x) und Hintergrund einzuhalten.
Die Einsatzbedingungen prüfen:
Schaltabstand und Distanz zum Objekt bzw. Hintergrund sowie Remissionsvermögen
des Objekts mit dem zugehörigen Diagramm abgleichen (x = Schaltabstand, y =
Mindestabstand zwischen eingestelltem Schaltabstand und Hintergrund (weiß, 90%))
Remission: 6 % = schwarz 1, 18 % = grau 2, 90 % = weiß 3 (bezogen auf Standard‐
weiß nach DIN 5033). Wir empfehlen, die Einstellung mit einem Objekt von niedriger
Remission vorzunehmen.
Die minimale Distanz (= y) für die Hintergrundausblendung kann aus dem Diagramm
wie folgt ermittelt werden:
Beispiel: x = 100 mm, y = 4 mm. D. h. der Hintergrund (weiß, 90%) wird ab einer
Distanz von > 4 mm vom Sensor ausgeblendet.
