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 GSE6L is an opto-electronic through-beam photoelectric sensor (referred to as
“sensor” in the following) for the optical, non-contact detection of objects. A sender
(GS) and a receiver (GE) are required for operation. If the product is used for any other
purpose or modified in any way, any warranty claim against SICK AG shall become void.

NOTE
When mounting through beam photoelectric sensors adjacent to each other, alternate
the sender (GS6L) and receiver (GE6L) arrangement every other pair. Also ensure
that there is sufficient distance between pairs based on the sender (GS6L) light spot
diameter. Refer to figure 1 and figure 2.

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

7 Commissioning
7.1 Alignment
Align the sender with the receiver. Select the position so that the red emitted light beam
hits the receiver. Tip: Use white paper or a reflector as an alignment aid. The sender
must have a clear view of the receiver, with no object in the path of the beam [see
figure 3]. You must ensure that the optical openings (front screen) of the sensors are
completely clear.
Figure 3: Alignment
7.2 Sensing range
Observe the application conditions: Adjust the distance between the sender and the
receiver according to the corresponding diagram [see figure 4] (x = sensing range, y =
operating reserve).
When mounting through beam photoelectric sensors adjacent to each other, alternate
the sender (GS6L) and receiver (GE6L) arrangement every other pair. Also ensure
that there is sufficient distance between pairs based on the sender (GS6L) light spot
diameter. By doing this, mutual interference can be prevented [see figure 1].
Use table 3 to check the function. If the switching output fails to behave in accordance
with table 3, check the application conditions.

7.3 Settings
Sensitivity setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
The sensitivity is adjusted with the potentiometer (type: 5-turn). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced. We
recommend setting the potentiometer to “Maximum”.
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 receiver and
there is no object in the path of
the beam
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
receiver. / Clean the optical
surfaces / If the potentiom‐
eter is set to the max. sen‐
sitivity: Reduce the distance
