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 Product description
3.1 Intended use
The WTB4F is an opto-electronic photoelectric background suppression proximity sen‐
sor (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.
3.2 Operating elements and status indicators

4 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of accesso‐
ries).
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.
5 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.

6 Commissioning
6.1 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].
Align the sensor with a fixed background. You must ensure that the optical opening
(front screen) of the sensor is completely clear [see figure 2].

6.2 Check the application conditions:
Sensing range
WTB4F 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 background is to be
maintained.
Check the application conditions:
Adjust the sensing range and distance to the object or background as well as the
remission capability of the object according to the corresponding diagram (x = sensing
range, y = minimum distance between set sensing range and background (white, 90%))
Remission: 6% = black 1, 18% = gray 2, 90% = white 3 (relative 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 figure figure 4 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.
NOTE
Observe the minimum distance of 5 mm.
