Through-beam photoelectric sensor
Operating instructions
2 Safety notes
■Read the operating instructions before commissioning.
■Connection, mounting, and setting may only be performed by trained specialists.
■Not a safety component in accordance with the EU Machinery Directive. Only for use in appli‐
cations in accordance with NFPA 79. UL-listed adapters with connecting cables are available.
Enclosure type 1
■When commissioning, protect the device from moisture and contamination.
■These operating instructions contain information required during the life cycle of the sensor.
3 Correct use
The GRSE18 is an opto-electronic through-beam photoelectric sensor (referred to as "sensor" in
the following) for the optical, non-contact detection of objects, animals, and persons. A sender
(WS) and a receiver (WE) 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.

4 Commissioning
1 Observe the application conditions: Adjust the distance between the sender and the receiver
according to the corresponding diagram (x = sensing range, y = operating reserve).
If several through-beam photoelectric sensors which are installed next to one another are to
be used, we recommend swapping the sender/receiver arrangement at every second
through-beam photoelectric sensor and ensuring that there is sufficient distance between
the through-beam photoelectric sensors. By doing this, mutual interference can be preven‐
ted.

2 Mount sensors (sender and receiver) using suitable mounting brackets (see the SICK range
of accessories). Align the sender and receiver with each other [K].
Observe the maximum permissible tightening torque of the sensor of 2.0 Nm for metal/0.9
Nm for plastic [K].

3 The sensors must be connected in a voltage-free state (VS = 0 V). The information in the gra‐
phics [B] must be observed, depending on the type of connection:
– Male connector connection: pin assignment
– Cable: core color
Image: B: GRSE18-x11xx
Only apply voltage/switch on the power supply (VS > 0 V) once all electrical connections have
been completed. The green LED indicator lights up on the sensor.
Explanations of the connection diagram (Graphic B):
Switching outputs Q and /Q (according to Graphic B):
GRSE18-P (PNP: load -> M)
GRSE18-N (NPN: load -> L+)
TI = test input (see Additional functions)
4 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. No light spot is visible
with infrared devices. The correct alignment can only be detected via the LED indicators.
Please refer to Graphics C and E in relation to this. The sender must have a clear view of the
receiver, and no object may be in the optical path. You must ensure that the optical open‐
ings (front screen) of the sensors are completely clear.

Sensor with potentiometer:
The sensitivity is adjusted with the potentiometer (type: 270°). 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. Refer to Graphics C and G to check the func‐
tion. If the switching output fails to behave in accordance with Graphic C, check application
conditions. See section Fault diagnosis.

6 Additional functions
The GRSE18 sensor features a test input ("TI" on the connection diagram [B]), which can be used
to check that the sensor is functioning correctly: If cable sockets with LED indicators are used,
you must ensure that the TI is assigned accordingly.
There must be no object between the sender and receiver; activate the test input (see the con‐
nection diagram [B], TI at 0 V). The send LED is shut down or the detection of an object is simula‐
ted. Refer to Graphics C and G to check the function. If the switching output fails to behave in
accordance with Graphic C, check application conditions. See section Fault diagnosis.

9 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regulations. Efforts
should be made during the disposal process to recycle the constituent materials (particularly pre‐
cious metals).
10 Maintenance
SICK sensors are maintenance-free.
We recommend doing the following regularly:
1. Clean the external lens surfaces
2. Check the screw connections and plug-in connections
No modifications may be made to devices.

15 Inbetriebnahme
1 Einsatzbedingungen beachten: Distanz zwischen Sender und Empfänger mit dem zugehöri‐
gen Diagramm [vgl. H] abgleichen (x = Schaltabstand, y = Funktionsreserve).
Beim Einsatz von mehreren Einweg-Lichtschranken, die nebeneinander installiert werden,
empfehlen wir, bei jeder zweiten Einweg-Lichtschranke die Anordnung von Sender und Emp‐
fänger zu tauschen, bzw. genügend Abstand zwischen den Einweg-Lichtschranken einzuhal‐
ten. Damit können gegenseitige Beeinflussungen vermieden werden [vgl. I].
