Operating instructions
1Safety 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.
■When commissioning, protect the device from moisture and contamination.
■These operating instructions contain information required during the life cycle of
the sensor.
2 Correct use
The HL18G/T is an opto-electronic photoelectric retro-reflective sensor (referred to as
"sensor" in the following) for the optical, non-contact detection of objects, animals, and
persons. A reflector is required for this product to function. If the product is used for any
other purpose or modified in any way, any warranty claim against SICK AG shall become
void.
Photoelectric retro-reflective sensor with optional add-on for detecting transparent ob‐
jects (HLxxG-xxxx).
The HL18G/T sensor complies with the Radio Safety Requirements (EMC) for the in‐
dustrial sector (Radio Safety Class A). It may cause radio interference if used in a resi‐
dential area.

1 Adjust the distance between the sensor and the reflector according to the corre‐
sponding diagram [H] (x = sensing range, y = operating reserve).

2 Mount the sensor and the reflector using suitable mounting brackets (see the SICK
range of accessories). Align the sensor and reflector with each other.
Note the sensor's maximum permissible tightening torque of 0.56 Nm.
3 The sensors must be connected in a voltage-free state (Uv = 0 V). The information
in the graphics [B] must be observed, depending on the connection type:
– Male connector connection: pin assignment
– Cable: core color
Only apply voltage/switch on the power supply (Uv > 0 V) once all electrical connec‐
tions have been established. The green LED indicator on the top of the sensor
lights up.
Explanations of the connection diagram (Graphic B):
Switching outputs Q and /Q (according to Graphic B):
Switching output Q (according to Graphic B):
HL18G/T-P (PNP: load -> M)
HL18G/T-N (NPN: load -> L+)
L = light switching
D = dark switching
4 Align the sensor with a suitable reflector. Select the position so that the red emit‐
ted light beam hits the center of the reflector. Tip: Use the signal strength light bar
on the back of the sensor to help you align it correctly. The sensor must have a
clear view of the reflector, with no object in the path of the beam [see Graphic E/F].
You must ensure that the optical openings of the sensor and reflector are comple‐
tely clear.
Optimized alignment can be achieved and verified by using the signal strength light
bar located on the back cover of the sensor. The LEDs on the light bar will illumina‐
te corresponding to the signal strength of light received by the sensor. When no or
only red LEDs are illuminated, the sensor is receiving no or too little signal to switch
the output. The first yellow LED will illuminate at the minimum switching threshold
and the green LEDs will continue to illuminate as the received light increases [see
Graphic F].

HL18T/G: Sensor with potentiometer:
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation:
operating reserve increased; counterclockwise rotation: operating reserve reduced.
Adjustment for detecting transparent objects (> 10% damping): Place object betwe‐
en sensor and reflector. Reduce the sensitivity until the LED indicator goes out. On‐
ce the object is removed, the LED indicator must light up again. If the LED indicator
does not light up again, check the application conditions.
HL18T: The sensor has a continuous threshold adaptation function. 3 different
operating modes can be set based on the desired signal damping level. To do this,
align the sensor with the reflector and turn the potentiometer clockwise until the
yellow LED on the top side of the sensor starts to flash. The green LED flashes at
the start of each mode.
Mode I for PET bottles: Activates at a signal damping level > 10% (teach time: 1 ...
5 s)
Mode II for glass: Activates at a signal damping level > 18% (teach time: 5 ... 10 s)
Mode III for colored glass or non-transparent objects: Activates at a signal damping
level > 40% (teach time: > 10 s)
Once the Teach process is complete, turn the potentiometer one full rotation coun‐
terclockwise. Teach-in mode is terminated, and the yellow LED stops flashing.
The sensor is adjusted and ready for operation. 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.

5 Additional functions
Time types: HL18G/T with optional On-delay or Off-Delay adjustment: t0 = no time de‐
lay, t1 = time delay when object is detected, t2 = time delay when no object is detected.
The time setting can be selected using the potentiometer according to A.
dark switching light switching
2 1 t = 1
1 2 t = 2
Timer stages can be set from 0 to 2 seconds.
Light/dark switch: The sensor is in light switching mode when optional light/dark poten‐
tiometer is rotated to the “L” position. The sensor is in dark switching mode when optio‐
nal light/dark potentiometer is rotated to the “D” position. The green power supply LED
will flash once when the mode is changed.

2 Sensor und Reflektor an geeignete Befestigungswinkel montieren (siehe SICK-Zu‐
behör-Programm). Sensor und Reflektor zueinander ausrichten.
Maximal zulässiges Anzugsdrehmoment des Sensors von 0.56 Nm beachten.
3 Anschluss der Sensoren muss spannungsfrei (UV = 0 V) erfolgen. Je nach An‐
schlussart sind die Informationen in den Grafiken [vgl. B] zu beachten:
– Steckeranschluss: Pinbelegung
– Leitung: Adernfarbe
Erst nach Anschluss aller elektrischen Verbindungen die Spannungsversorgung (UV
> 0 V) anlegen bzw. einschalten. Am Sensor leuchtet die grüne Anzeige-LED auf der
Sensor-Oberseite.

4 Sensor auf geeigneten Reflektor ausrichten. Positionierung so wählen, dass der ro‐
te Sendelichtstrahl in der Mitte des Reflektors auftrifft. Tipp: Die Anzeige der Sig‐
nalstärke auf der Sensor-Rückseite hilft bei der korrekten Ausrichtung. Der Sensor
muss freie Sicht auf den Reflektor haben, es darf sich kein Objekt im Strahlengang
befinden [vgl. Grafik E/F]. Es ist darauf zu achten, dass die optischen Öffnungen
von Sensor und Reflektor vollständig frei sind.
Die optimale Ausrichtung kann mit Hilfe der Anzeige der Signalstärke auf der Sen‐
sor-Rückseite erreicht und geprüft werden. Die LEDs auf der Anzeige der Signal‐
stärke leuchten in Abhängigkeit mit der Signalstärke des empfangenen Lichts des
Sensors. Leuchtet keine LED oder nur die roten LEDs, empfängt der Sensor kein
oder kein ausreichendes Signal, um den Ausgang zu schalten. Die erste gelbe LED
leuchtet, sobald die Mindestschaltschwelle erreicht ist, was zum Schalten des Aus‐
gangs führt. Die grünen LEDs zeigen die Funktionsreserve an. Je besser die Funkti‐
onsreserve (empfangenes Licht), desto mehr grüne LEDs leuchten [vgl. Grafik F].

HL18T/G: Sensor mit Potentiometer:
Mit dem Potentiometer (Art: 270°) wird die Empfindlichkeit eingestellt. Drehung
nach rechts: Erhöhung der Funktionsreserve, Drehung nach links: Verringerung der
Funktionsreserve. Einstellung zur Detektion transparenter Objekte (> 10 % Dämp‐
fung): Objekt zwischen Sensor und Reflektor stellen. Die Empfindlichkeit soweit re‐
duzieren, bis die Anzeige-LED erlischt. Nach Entfernen des Objekts muss die Anzei‐
ge-LED wieder leuchten. Leuchtet die Anzeige-LED nicht wieder, Einsatzbedingun‐
gen prüfen.
