2.3 Intended use
The KTML contrast sensor is an opto-electronic sensor for the optical, non-contact
detection of contrasts.
A contrast sensor is designed for mounting and may only be operated according to its
intended function. For this reason, it is not equipped with direct safety devices.
The system designer must provide measures to ensure the safety of persons and
systems in accordance with the legal guidelines.
SICK AG assumes no liability for losses or damage arising from the use of the product,
either directly or indirectly. This applies in particular to use of the product that does not
conform to its intended purpose and is not described in this documentation.
UL: Only for use in application in accordance with NFPA79.
2.4 Improper use
•The device does not constitute a safety-relevant device according to the EC Machi‐
nery Directive (2006/42/EC).
•The device must not be used in explosion-hazardous areas.
•Any other use that is not described as intended use is prohibited.
•Any use of accessories not specifically approved by SICK AG is at your own risk.
The device is not suitable for the following applications (this list is not exhaustive):
•As a safety device to protect persons, their hands, or other body parts
•Underwater
•In explosion-hazardous areas
•Outdoors, without additional protection
NOTICE
Danger due to improper use!
Any improper use can result in dangerous situations.
Therefore, observe the following information:
►The device should be used only in line with intended use specifications.
►All information in these operating instructions must be strictly complied with.

3.1 Scope of delivery
•Contrast sensor in the version ordered
•Quickstart
•Safety notes
3.2 Mounting requirements
•Typical space requirement for the device, see type-specific dimensional drawing,
see "Technical data", page 22.
•Comply with technical data, such as the permitted ambient conditions for opera‐
tion of the device (e.g., temperature range, EMC interference emissions, ground
potential).
•To prevent condensation, avoid exposing the device to rapid changes in tempera‐
ture.
•Protect the device from direct sunlight.
•The device must only be mounted using the pairs of mounting threads/fixing holes
provided for this purpose.
•Shock and vibration-free mounting.
3.3 Mounting the device
üû
Figure 1: KTML
1. Install the sensor via the fixing hole so that the light spot enters the mark
longitudinally and the test object has the least possible vertical and horizontal
movement. Note the sensing distance while doing so.
2. Compensate for the vertical and horizontal movement of the test object by marks
of suitable lengths.
3. Ensure that any sensor movement does not affect the sensing distance.
To secure a stable detection when having high gloss material a tilt angle of 10°-15°
might be necessary.

s ≤ 3 s).
> 1 s ≤ 3 s

✓The optimum emitted light is automatically selected. The switching threshold is set
in the center between the mark’s receive signal and background and is stored in a
nonvolatile memory. Output active by mark (first teach-in).
This example is showing dark switching (switch on the mark):
NOTE
Light / dark switch:
The light/dark setting is defined using teach-in sequence.
Light switch can be achieved by teaching the background first and then the mark.

Switching threshold ‘’close to mark’’ via teach-in-button
NOTE
By default, the switching threshold is set in the center between the background and the
mark. In the event of intermittent error switching on the background, it may be helpful
to place the threshold close to the mark to increase stability (dotted line instead of solid
line in the figure below).

to be reset to the center, new teach-in is required.
NOTE

8 Maintenance
8.1 Maintenance
During operation, the device works maintenance-free.
Depending on the assignment location, the following preventive maintenance tasks
may be required for the device at regular intervals:
Table 3: Maintenance schedule
Maintenance work Interval Implementation
Clean housing and front screen Cleaning interval depends on ambi‐
ent conditions and climate
Specialist
Check screw connections and plug
connectors
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!
►Clean the light emission window only when wet.
►Use a mild cleaning agent that does not contain powder additives. Do not use
aggressive cleaning agents, such as acetone, etc.
►Avoid any movements that could cause scratches or abrasions on the light emis‐
sion window.
►Only use cleaning agents suitable for the lens 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.
