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.
■
When commissioning, protect the device from moisture, contamination and
UV radiation (sun light).
■These operating instructions contain information required during the life cycle of
the sensor.
2 Notes on UL approval
The device must be supplied by a Class 2 source of supply.
UL Environmental Rating: Enclosure type 1
3 Intended use
The GTB2F is an opto-electronic photoelectric 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.
4 Operating and status indicators
Photoelectric proximity sensor with background suppression.

5 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.1 Nm.
Note the preferred direction of the object relative to the sensor, cf. see "Dimensional
drawing", page 11.
6 Electrical installation
The sensors must be connected in a voltage-free state (UV = 0 V). The following informa‐
tion must be observed, depending on the connection type:
– Plug connection: note pin assignment: when the lid is open, the male connector
can be swiveled horizontally and vertically.
– Cable: wire color
Only apply voltage/switch on the voltage supply (UV > 0 V) once all electrical connec‐
tions have been established.
Explanation of the connection diagram (Tables pin assignment):
Q = switching outputs
n. c. = not connected
DC: 10 ... 30 V DC

7 Commissioning
1Alignment
Align sensor on object. Select the position so that the red emitted light beam hits the cen‐
ter of the object. You must ensure that the optical opening (front screen) of the sensor is
completely clear.

2Sensing range
Check the application conditions: Adjust the sensing range and distance to the object or
background and the remission capability of the object according to the corresponding dia‐
gram [see table 3].

Use see table 2, page 7 to check the function. If the switching output fails to behave in
accordance with the table, check the application conditions. See section Fault diagnosis.

Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
8 Troubleshooting
The Troubleshooting table indicates measures to be taken if the sensor stops working.
Table 4: Troubleshooting
LED indicator/fault pattern Cause Measures
Yellow LED does not light up
even though the light beam is
aligned to the object and the
object is within the set sensing
range
No voltage or voltage below
the limit values
Check the power supply,
check all electrical connec‐
tions (cables and plug connec‐
tions)
Voltage interruptions Ensure there is a stable power
supply without interruptions
TROUBLESHOOTING 8
8023328.18HX | SICK
Subject to change without notice 9
LED indicator/fault pattern Cause Measures
Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED lights up, no object
in the path of the beam
The sensing range distance is
too large
Reduce the sensing range,
see Figures 6-8 and table 3
Object is in the path of the
beam, yellow LED does not
light up
Distance between the sensor
and the object is too long or
sensing range is set too short
Increase the sensing range,
see Figures 6-8 and table 3
9 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, indi‐
cates that a product is subject to these regulations.
10 Maintenance
SICK sensors are maintenance-free.
We recommend doing the following regularly:
•Clean the external lens surfaces
•Check the screw connections and plug-in connections
No modifications may be made to devices.
