5 Mounting
Mount the sensor using a suitable mounting bracket (see the SICK range of acces‐
sories).
NOTE
Note the sensor's maximum permissible tightening torque of 0.56 Nm.
6 Electrical installation
Operation in standard I/O mode:
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.
The green LED indicator on the top of the sensor lights up.
Operation in IO-Link mode: Connect the device to a suitable IO-Link master and inte‐
grate in the master or control via IODD/function block. The green LED indicator flashes
on the sensor. IODD and function block are available to download from www.sick.com
under the part number.

6.3 Adjustments
L/D Switching
The sensor may be specified with a Light Switching or Dark Switching
(L/D) selection potentiometer.
Light Switching is selected for the Q1 output by rotating the poten‐
tiometer counterclockwise to the stop position. The potentiometer tab
will point toward the “L” printed on the sensor housing.
Dark Switching is selected for the Q1 output by rotating the poten‐
tiometer clockwise to the stop position. The potentiometer tab will
point toward the “D” printed on the sensor housing.
CAUTION
Over rotation of the potentiometer past the stop positions will cause permanent dam‐
age to the sensor.
If complimentary outputs are specified (Hx18-Pxxxxx, Hx18-Nxxxxx, Hx18-Fxxxxx), the
Q2 output will always be opposite switching state of the Q1 output. Therefore, the Q2
output will be Dark Switching when the potentiometer is in the “L” position and Light
Switching in the potentiometer is in the “D” position. If bipolar outputs are specified
(Hx18-Axxxxx, Hx18-Bxxxxx), the Q2 output will always have the same switching state
as the Q1 output. The L/D selection potentiometer does not impact a Health or Alarm
output (if specified).

Time delay
The sensor may be specified with an adjustable time delay. The delay
time is adjusted by rotating the 270° potentiometer.
Clockwise rotation in the direction of the “+” printed on the sensor will
increase the delay time (TDELAY). Maximum Delay time will occur at the
clockwise stop position.
Counter clockwise rotation in the direction of the “-“ printed on the
sensor will decrease the delay time. There will be no time delay at the
counter clockwise stop position.
CAUTION
Over rotation of the potentiometer past the stop positions will cause permanent dam‐
age to the sensor.
A L/D selection switch may be specified with an adjustable time delay. Adjustable time
delay does not impact a Health or Alarm output (if specified).

7 Commissioning
7.1 Alignment
Sensor with infrared light (not visible):
Align sensor on object. Select the position so that the infrared light 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. See figure 1 and table 1.
You must ensure that the optical opening (front screen) of the sensor is completely
clear.
Figure 1: Alignment
7.2 Check the application conditions
Sensing range
Check the application conditions: Adjust the sensing range and the remission capability
of the object according to the corresponding diagram [see table 10]. (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.

Sensing range setting
Sensor which it is not possible to set: The sensor is adjusted and ready for operation.
Refer to graphic to check the function. If the switching output fails to behave in accor‐
dance with graphic, check application conditions. See section Fault diagnosis.
Sensor with potentiometer (without IO Link):
The sensing range is adjusted relative to the background with the potentiometer (type:
270°).
Clockwise rotation: sensing range increased; counterclockwise rotation: sensing range
reduced.
Turn the potentiometer clockwise until the yellow LED indicator lights up. When an
object is moved into the path of the beam, the yellow LED indicator must go out. If the
yellow LED indicator remains lit when an object is moved into the path of the beam,
repeat the adjustment.

Sensor with potentiometer (with IO Link):
The sensing range is adjusted relative to the background with the potentiometer (type:
270°).
Clockwise rotation: to teach mode; counterclockwise rotation: to run mode. Turn the
potentiometer clockwise to teach mode until yellow LED begins blinking. Set object
at desired sensing range. Turn the potentiometer counterclockwise to run mode until
yellow LED stops blinking. The yellow LED should remain lit. Remove the object from

Figure 5: Signal strength light bar during adjustment
The optimum 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 object position and the set switching point. If no LEDs or only the red LEDs
light up, the object is positioned in front of the set switching point and cannot be
detected. The first yellow LED lights up when the object is behind the set switching
point. More green LEDs light up when the object is moved further away from the sensor
into the background (see figure 5). The sensor is adjusted and ready for operation.
Refer to graphics see table 1, page 7 to check the function. If the switching output fails
to behave in accordance the graphic, check application conditions. See section Fault
diagnosis.
Please refer to the enclosed operating instructions for the IO-Link photoelectric sensor
for information about adjusting the IO-Link sensing range.
The sensor is adjusted and ready for operation.
7.4 Additional functions
Alarm / Health output
The sensor (HTE18) features a pre-failure notification output (“Q2” in connection dia‐
gram [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 conta‐
minated, sensor is out of alignment. In the good state: LOW (UV < V); if excessively
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
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.
Timer stages can be set from 0 to 2 seconds.
