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

ATTENTION
WARNING: Interruption, manipulation or incorrect use can lead to hazardous exposure
due to laser radiation.
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 GTE6L is an opto-electronic photoelectric proximity sensor (referred to as “sensor”
in the following) for the optical, non-contact detection of objects. If the product is used
for any other purpose or modified in any way, any warranty claim against SICK AG shall
become void.

Mount the sensor using a suitable mounting bracket (see the SICK range of accesso‐
ries).
Note the preferred orientation of the sensor relative to the direction of object motion,
refer to figure 1.

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: pin assignment
– Cable: wire color
Only apply voltage/switch on the voltage supply (UV > 0 V) once all electrical connec‐
tions have been established.
Explanation of connection terminology:
BN = Brown
WH = White
BU = Blue
BK = Black
n. c. = no connection
Q = switching output 1
Q = switching output 2
L+ = supply voltage (Uv)
M = common
L.ON = light operate
D.ON = dark operate

7 Commissioning
7.1 Alignment
Align sensor on 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].
Figure 2: Alignment
7.2 Sensing range
Check the application conditions: Adjust the mounting position so that the sensing
range and remission capability are within the corresponding diagram [see see figure 3].
(x = sensing range, y = operating reserve).
During this process, an object can only be detected in front of a background if the
remission capability of the object is significantly higher than that of the background or if
the distance between the object and the background is sufficiently long.

7.3 Settings
Sensing range setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensitivity (sensing range) is adjusted with the potentiometer (type: 5-turn). Clock‐
wise rotation: sensitivity (sensing range) increased; counterclockwise rotation: sensitiv‐
ity (sensing range) reduced. We recommend placing the object within the sensing
range, e.g. see figure 3. Once the sensitivity is set, remove the object from the beam
path. The switching output changes.
Table 3: Adjustment sensing range
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
Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
