Optional settings
FLEX MOUNT
If the sensor is mounted at an angle or the reference surface is not at the End of the measuring range Sde,
FLEX MOUNT must be activated and the reference surface taught in.
If FLEX MOUNT is activated, the following settings are reset: SCALE OUT, FIELD OF VIEW and DIGITAL
OUT.
OBJECT
Selection of bright or dark objects to optimize the measurement results.
PRECISION
To achieve better precision and resolution, it is possible to alternate between Standard, High and Very High
by filtering the output values.
SCALE OUT
Start of measuring range Sdc and end of measuring range Sde can be changed with SCALE OUT. 0V or 4mA
then apply for the start of measuring range Sdc. 10V or 20 mA apply for the point at the end of measuring
range Sde.
FIELD OF VIEW
The width of the measuring field can be changed with FIELD OF VIEW. Separate configuration of the single
points of the field: LIMIT LEFT, LIMIT RIGHT.
This function is required when there are objects in the measuring field that should not be detected.
ANALOG OUT
Start of measuring range Sdc (Offset) and end of measuring range Sde (Height) can be changed with SCALE
OUT. 0V or 4mA then apply for the start of measuring range Sdc. 10V or 20 mA apply for the point at the end
of measuring range Sde. Voltage and current output is selected under ANALOG OUT. In addition, the output
curve can be inverted under OUTP. SLOPE.
DIGITAL OUT
The sensor is equipped with a switching output that can be configured as a threshold or as a window via the
DIGITAL OUTPUT function.
Threshold: As soon as the measuring value is greater than the entered threshold, the switching output will be
changed.
Window: As soon as the measuring value is outside the entered window, the switching output will be changed.
Let's get started
The sensor continuously outputs the measuring value in mm to the display and transmits it via the analog
output to the control.

3 Connection
3.1 Connection cable
An 8-pole, shielded connection cable (cable socket) is required.
We recommend the ipf connection cables with the following article numbers:
•VK205A21/25 (Length 2m, M12 socket angular/straight)
•VK505A21/25 (Length 5m, M12 socket angular/straight)
•VKA05A21/25 (Length 10m, M12 socket angular/straight)
Other cable lengths are available.
When the analog output is used, the cable length affects signal noise. Signal noise increases the longer the
connection cable is.
Analog output I_OUT
Noise: 5.92 uA (1 Sigma) (10 m cable and 680 ohm)
3:59 uA (1 sigma) (2m cable and 680 ohm)
Analog output U_OUT
Noise: 4.80 mV (1 Sigma) (10m cable and 100 kOhm)
3:03 mV (1 Sigma) (2m cable and 100 kOhm)
ATTENTION!
Laser class 1 laser beam according to EN 60825-1:2007. This product can be
operated safely without any additional safety precautions. Nevertheless direct
contact between the eye and beam should be avoided.
ATTENTION!
The IP protection class is valid only if all connections are connected as
described in the technical documentation.
ATTENTION!
Connection, installation and commissioning may only be performed by qualified
personnel.
ATTENTION!
Incorrect supply voltage will destroy the device!

4 Installation
4.1 Mounting
The sensor has four mounting holes for flexible alignment and mounting. The use of 2 M4x35 screws is
recommended for mounting. The tightening torque is max. 1.2 Nm.
4.2 Sensor reference levels
To ensure easy alignment of the sensor during installation, the surfaces defined here are available:
The laser beam of the sensor runs parallel ( // ) to level R3 and is at a right angle to levels R1 and R2. Levels
R1, R2, and R3 serve as references for sensor alignment during installation. "Left" and "Right" designations
are also important.

4.3 The reference surface
If the height of the object is to be measured from a specific surface or the sensor is mounted at an angle up to
±30°, then the reference surface must be taught in with the FLEX MOUNT function.
The following points must be satisfied for teaching in the reference surface:
•The reference surface must lie within the measuring range of the sensor.
•The sensor may be inclined at a maximum angle of ±30° to the reference surface.
•The "Maximum reference surface unevenness"1must not exceed the maximum value.
•The length of the reference surface must not be less than the "minimum reference surface length"1
value.
1According to data sheet chapter 6.1
NOTE
The reference surface…
•should be as flat as possible
•should cover the entire measuring range (width) if possible
•can be teached-in with the FLEX MOUNT function

4.4 Measuring field defintion
The maximum measuring field and additional important measuring field definitions are described in the
following diagram. The important terms "left" and "right" are to be regarded respectively from the viewpoint of
the connector side of the sensor.
The sensor measures the height of objects within the measuring field. With the HEIGHT
function, it is the end of measuring range Sde or optionally the teach-in reference surface
(If FLEX MOUNT is active).
NOTE
For further explanations, see section "Function and definition“ -> "Interfaces and
output" -> "Interfaces and output-> "Analog signal output".

4.4.1 Blind region
The region from sensor level R2 up to the start of measuring range Sdc is called the blind region, i.e. the
sensor cannot detect any objects there.
Objects in this area can cause incorrect measuring values.

4.5 Mounting
The sensor can be installed at an inclination of up to ±30° to the reference surface. This is particularly useful
when space conditions do not allow any other installation option. See chapter FLEX MOUNT.
After activation of FLEX MOUNT, the sensor axis is no longer relevant. The measurement coordinate system
is now represented by the M and K axes. The height is now measured in M-direction.
4.5.1 Reference point with inclined installation
In the case of angled installation, the zero point (0 mm) of the K axis shifts out of the center of the measuring
field or the red visible laser line. Due to inclination of the sensor, the two measuring field sections, "measuring
field width left" and "measuring field width right", are no longer equal in size.

4.5.2 Practical zero point search
The LIVE MONITOR mode can be used to find the
reference point (0 mm). This function displays the
LEFT EDGE RISING (the first rising edge from the
left side) of objects. Now an object is slowly pushed
toward the presumed zero point. The zero point is
reached when the value 0 mm is shown on the
sensor display.
NOTE
If the sensor is mounted inclined, FLEX MOUNT has to be activated.

4.6 Installation accessories
To ensure optimal mounting, the mounting bracket AP000043 is available as an accessory. This bracket fits
best with the ball-head holder AY000143.
The sensor can be aligned within the entire pivoting radius of the ball-head.
4.6.1 Mounting kit for PY74 series
With the mounting bracket AP000043 and the ball-head AY000143 the sensor can be mounted quickly and
easily in any orientation.
