Notes
Adjusting the switching points
•Object teach:
Align sensor with object.
Q1: Press teach button for approx.
2s,
Q2: Press teach button for approx.
7s
Switching point is taught.
Object is detected if the respective
Q1/Q2 indicator illuminates.
•Hysteresis:
To ensure continuous object detec-
tion in the switching point, the sensor
has a switch hysteresis.
Object is no longer detected if:
distance to sensor > teach point +
reserve + hysteresis.
•Factory setting:
Hysteresis: 30 mm (adjustable),
reserve: 30 mm (adjustable)
Application notes
• With the set detection range, a toler-
ance of the upper scanning range
limit is possible depending on the
reflection properties of the material
surface.
• Range/reflectivity:
• Reflective, high-gloss objects (e.g.
mirrors) are not detected.
• Optimum detection behavior is
achieved when the light spot is fully
on the object.
• The maximum possible angle rela-
tive to the object surface depends on
the reflection properties.
• An only partially covered light spot
can affect the detection behavior.

IO-Link interface (only HRT 25B/L…)
Sensors in the HRT 25B/L… variant have a dual channel architecture. The IO-Link interface in accordance with specification 1.1.1
(October 2011) is provided on pin 4 (Q1). This allows the devices to be configured quickly and easily and, therefore, cost-effec-
tively. Furthermore, the sensor transmits its process data and makes diagnostic information available through it.
Parallel to the IO-Link communication, the sensor can output the continuous switching signal for object detection on Q2. The
IO-Link communication does not interrupt this signal.

Sensor adjustment (teach) via teach button
The sensors have a factory-set hysteresis H of 50mm.
Operation via teach button
Teach-in on operating level 1 (switching distance for Q1)
• Press teach button until both LEDs flash simulta-
neously.
• Release teach button.
• Ready.
Teach-in on operating level 2 (switching distance for Q2)
• Press teach button until both LEDs flash alter-
nately.
• Release teach button.
• Ready.
Teach Operating level 1 Operating level 2
Teaching of two
individual switching points
Teach on object for Q1 (pin 4):
With this teach mode, the switching distance for
switching output Q1 is configured in such a way
that the object which is in the beam path during
the teach procedure is reliably detected.
Teach on object for Q2 (pin 2):
With this teach mode, the switching distance for
switching output Q2 is configured in such a way
that the object which is in the beam path during
the teach procedure is reliably detected.
Hysteresis H:
To ensure continuous object detection in the switching point, the sensor has a switch hysteresis.
Object is no longer detected if: distance to sensor > teach point + reserve + hysteresis.

Adjusting the switching behavior of the switching output – light/dark switching
This function permits inversion of the sensors' switching logic.
• Press teach button until only the green LED
flashes. Yellow LED:
ON = switching outputs light switching (in
the case of complementary sensors,
Q1 (pin 4) light switching, Q2 (pin 2)
dark switching), this means output
active when object is detected.
OFF = switching outputs dark switching (in
the case of complementary sensors,
Q1 (pin 4) dark switching, Q2 (pin 2)
light switching), this means output
inactive when object is detected.
• Release teach button.
The yellow LED then indicates the toggled switch-
ing logic.
• Ready.
Set factory defaults
It's possible to restore the factory settings of the sen-
sor via the teach button.
• Hold down the teach button during power-on. The
green and yellow LEDs flash simultaneously at
3Hz.
• Release the teach button. The green and yellow
LEDs flash alternately at 3Hz.
• Press the teach button. The green and yellow
LEDs flash simultaneously at 9Hz.
• Release the teach button. The factory settings are
restored and the sensor is restarted.
The sequence must be completed within 10s, other-
wise the factory settings will not be restored.

Sensor adjustment (teach) via teach input (pin 2)
The following description applies to PNP switching logic!
Signal level LOW 2V
Signal level HIGH (UB-2V)
With the NPN models, the signal levels are inverted!
Line teach on operating level 1 (switching distance for Q1)
Line teach on operating level 2 (switching distance for Q2)
Light switching logic
Switching outputs light switching, this means outputs active when object is detected.
In the case of complementary switching outputs, Q1 (pin 4) light switching, Q2 (pin 2) dark switching.
Dark switching logic
Switching outputs dark switching, this means outputs inactive when object is detected.
In the case of complementary switching outputs, Q1 (pin 4) dark switching, Q2 (pin 2) light switching.
Locking the teach button via teach input (pin 2)
A static high signal (20ms) at the teach
input locks the teach button on the sensor if
required, such that no manual operation is
possible
(e.g., protection from erroneous operation or
manipulation).
If the teach input is not connected or if there
is a static low signal, the button is unlocked
and can be operated freely.
