Operating instructions
1 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.
■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 HTE18 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.
Energetic photoelectric proximity sensor.
The HTE18 sensor complies with the Radio Safety Requirements (EMC) for the industri‐
al sector (Radio Safety Class A). It may cause radio interference if used in a residential
area.

3 Commissioning
1 Check the application conditions: Adjust the sensing range and the remission capa‐
bility of the object according to the corresponding diagram [H] (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.

2 Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
Note the sensor's maximum permissible tightening torque of 0.56 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.

Switching output Q (according to Graphic B):
HTE18-P (PNP: load -> M)
HTE18-N (NPN: load -> L+)
L = light switching
D = dark switching
Alarm / Health = diagnostics output (see Additional functions)
4 Align the sensor with the 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 Graphic E/F].
HTE18-xxx1xx: Align the sensor with the object. Select the position so that the inf‐
rared light (not visible) hits the center of the object. The correct alignment can be
detected via the signal strength light bar on the back of the sensor and the LED on
the top of the sensor. Please refer to Graphics E and F. You must ensure that the
optical opening (front screen) of the sensor is completely clear.

Sensor with potentiometer:
The sensitivity (sensing range) is adjusted with the potentiometer (type: 270°).
Clockwise rotation: sensitivity (sensing range) increased; counterclockwise rotation:
sensitivity (sensing range) reduced. We recommend placing the switching state in
the object, e.g., see graphic F. Once the sensitivity has been adjusted, the object is
removed from the path of the beam. The switching output changes (see graphic C).
The optimum alignment and setting can be achieved and checked using the signal
strength light bar on the back of the sensor. The LEDs on the signal strength light
bar light up in relation to the signal strength of the sensor's received light. If no
LEDs or only the red LEDs light up, the sensor is either receiving no signal at all or
is receiving insufficient signal to switch the output. As soon as the minimum swit‐
ching threshold is attained, the first yellow LED lights up, and the output switches.
The green LEDs display the operating reserve. The better the operating reserve (re‐
ceived light), the more green LEDs will light up (see graphic F).
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
Alarm output: The sensor (HTE18) features a pre-failure notification output (“Q2” in
connection diagram [B], if the alarm option is selected), which issues a notification if
the signal strength of the light being received is not sufficient. Possible causes: Sensor
is contaminated, sensor is out of alignment. In the good state: LOW (UV < V); if excessi‐
vely contaminated: HIGH (>+UV- V). The LED indicator flashes in this case.
Health output: The sensor (HTE18) features a health status notification output (“Q2” in
connection diagram [B], if the health option is selected), which issues a notification if
the signal strength of the light being received is sufficient. Possible causes, if the signal
strength is not sufficient: Sensors are contaminated, sensors are out of alignment, or
cable is damaged. In the good state: HIGH (>+UV- V); if excessively contaminated or in
the event of cable interruption: LOW (UV < V). The LED indicator flashes in this case.
Time types: HTE18 with optional On-delay or Off-Delay adjustment: t0 = no time delay,
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.

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.

8 Disassembly and disposal
The sensor must be disposed of according to the applicable country-specific regulati‐
ons. Efforts should be made during the disposal process to recycle the constituent ma‐
terials (particularly precious metals).
9 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.

1 Einsatzbedingungen prüfen: Schaltabstand und Remissionsvermögen des Objektes
mit dem zugehörigen Diagramm [vgl. H] abgleichen. (x = Schaltabstand, y = Funkti‐
onsreserve).
Dabei kann ein Objekt vor einem Hintergrund nur detektiert werden, wenn das Re‐
missionsvermögen des Objektes deutlich größer ist als das Remissionsvermögen
des Hintergrundes oder der Abstand zwischen Objekt und Hintergrund ausreichend
groß ist.
