3. Select the position so that the infrared light (not visible) hits the center of the
object. The correct alignment can only be detected via the LED indicators (yellow
indicator LED lights up when the object is detected) or with the help of an infrared
conversion screen (see the SICK range of accessories). see figure 2, page 11
4. Note the preferred direction of the object relative to the sensor. see figure 3,
page 11
5. Adjust the sensing range and distance to the object or background and the remis‐
sion capability of the object. see figure 4, page 11
6. You must ensure that the optical opening (front screen) of the sensor is completely
clear.
NOTE
The minimum distance for background suppression can be read as follows. Example:
Sensing range (= x axis) to a bright object is 400 mm. A dark background is suppressed
at a distance of 85 mm or more behind the object.
5 Electrical installation
5.1 Notes on the electrical installation
NOTICE
Equipment damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the equipment.
Only operate the device with safety/protective extra-low voltage (SELV/PELV).
The sensor is a device of protection class III.
NOTICE
Equipment damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the equipment.
Only operate the device with an LPS (limited power source) in accordance with IEC
60950-1 or an NEC Class 2 power supply unit.
NOTICE
Equipment damage or unpredictable operation due to working with live parts.
Working with live parts may result in unpredictable operation.
Only carry out wiring work when the power is off.
Only connect and disconnect electrical connections when the power is off.
The electrical installation must only be performed by electrically qualified person‐
nel.
Standard safety requirements must be met when working on electrical systems.
Only switch on the supply voltage for the device when the connection tasks have
been completed and the wiring has been thoroughly checked.
When using extension cables with open ends, ensure that bare wire ends do not
come into contact with each other (risk of short-circuit when supply voltage is
switched on!). Wires must be appropriately insulated from each other.
Wire cross-sections in the supply cable from the user’s power system must be
selected in accordance with the applicable standards.
Only operate the device with an LPS (limited power source) in accordance with IEC
60950-1 or an NEC Class 2 power supply unit.
All circuits connected to the device must be designed as SELV/PELV circuits.
Operation in short-circuit protected network at max. 8 A.

Subject to change without notice
NOTE
Layout of data cables
Use shielded data cables with twisted-pair wires.
Implement the shielding design correctly and completely.
To avoid interference, e.g., from switching power supplies, motors, clocked drives,
and contactors, always use cables and layouts that are suitable for EMC.
Do not lay cables over long distances in parallel with voltage supply cables and
motor cables in cable channels.
The IP enclosure rating for the device is only achieved under the following conditions:
The cables plugged into the connections are screwed tight.
Any electrical connections that are not being used must be fitted with protective
caps that are screwed tight (as in the delivery condition).
Any other lids present must be closed and lie flush on the device.
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!

Connecting the supply voltage
NOTICE
Risk of damage to the device!
The device can become damaged if it is connected to a voltage supply that is already
switched on.
Only connect the device when the supply cable is de-energized.
The device must be connected to a power supply unit with the following properties:
Supply voltage DC 10.8 V – 28.8 V (SELV/PELV as per currently valid standards)
Electricity source with at least 3 W power
To ensure protection against short-circuits/overload in the customer’s supply cables,
the wire cross-sections used must be appropriately selected and protected.

6.1 Sensing range setting
Q1
Figure 5: Sensing range setting
1 Position the object at the required distance and move it into the beam path of the
device (note the min. and max. ranges, see figure 5, page 14).
2 The sensing range is adjusted by pressing the single teach-in button (yellow LED
lights up).
NOTE
Note: The sensor automatically places the switching point in the object (teach-in offset
15 mm). Exception: When manually adjusting a mm value using an IO-Link, we recom‐
mend placing the switching point in the object.
NOTE
We recommend making the adjustments using an object with a low remission.
NOTICE
Do not operate the teach-in button using sharp objects.

Every 6 months Specialist
8.2 Cleaning the device
At regular intervals (e.g., weekly), check the light emission window and the housing of
the device for dirt. This is especially relevant in harsh operating environments (dust,
abrasion, damp, fingerprints, etc.). The lens of the light emission window must be kept
clean and dry during operation.
NOTICE
Device damage due to improper cleaning!
Improper cleaning may result in device damage.
Only use suitable cleaning agents.
Never use sharp objects for cleaning.
Cleaning the light emission window
NOTICE
Damage to the light emission window!
Reduced reading performance due to scratches or streaks on the light emission win‐
dow!
b
Clean the light emission window only when wet.
b
Use a mild cleaning agent that does not contain powder additives. Do not use
aggressive cleaning agents, such as acetone, etc.
b
Avoid any movements that could cause scratches or abrasions on the light emis‐
sion window.
b
Only use cleaning agents suitable for the screen material.
NOTE
Static charge may cause dust particles to stick to the light emission window. This effect
can be avoided by using an anti-static glass cleaner in combination with the SICK lens
cloth (can be obtained from www.sick.com).
NOTE
If the light emission window is scratched or damaged (cracked or broken), the device
must be replaced. Contact SICK Service to arrange this.
Cleaning the housing
In order to ensure that the heat produced by the internal power loss is adequately dissi‐
pated, the housing surface must be kept clean.
