2 Safety information
2.1 Intended use
The KTS contrast sensor is an opto-electronic sensor for the optical, non-contact detec‐
tion 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.

3.2.2 Product characteristics
Contrast sensors are primarily used in packaging or printing machines for detecting
marks.
However, they can also be used in any application based on making a distinction
between contrasts.
KTS contrast sensors detect even the smallest contrasts at the highest speeds, such as
print marks on foils or packaging. They detect minute grayscale variations between the
mark and the background on matte, shiny, or transparent surfaces. Device types are
available with different methods of contrast resolution and different teach-in variants
for a wide range of requirements.
Features
•12.5 kHz switching frequency
•Large dynamic range means reliable detection of contrasts on glossy materials
•7-segment display
•Color mode
•Flexible sensor setting thanks to various sensor parameters
Fields of application
•Applications in which contrast or color is a basic distinguishing feature
•Print mark detection for controlling the cutting process
•Print control in the print and paper industry
•Positioning of tubes when filling
•Label alignment on bottles
•Monitoring of wafer surfaces
•Roll end monitoring
•Color control in yarn or line production

4.3 Mounting the device
û
üû
Figure 2: KTS Core
1. Install the device via the fixing hole so that the light spot enters the mark longitudi‐
nally 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 device movement does not affect the sensing distance.

5 Electrical installation
5.1 Notes on the electrical installation
NOTICE
Device damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the device.
■Only operate the device with safety/protective extra-low voltage (SELV/PELV).
■The sensor is a device of protection class III.
NOTICE
Device damage due to incorrect supply voltage!
An incorrect supply voltage may result in damage to the device.
•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
Device 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.
NOTE
Layout of data cables
■Use screened data cables with twisted-pair wires.
■Implement the screening 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.
If these instructions are not complied with, the IP enclosure rating for the device is not
guaranteed!

5.2 Note on the swivel connector
NOTICE
Damage to the connector unit from over-tightening!
The connector unit on the device has two opposite end positions.
■Do not rotate the connector unit from either of the two end positions by more than
180°.

5.4 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 V – 30 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.
5.5 Wiring the interfaces
5.5.1 Wiring the digital inputs
The digital inputs can be used to start a teach-in procedure or to select a device
operating mode.
The number of digital inputs available at the connections will vary depending on the
device, see "Pin assignment of the connections", page 14.
Voltage level at the input starts the corresponding function of the device.

5.5.2 Wiring the digital outputs
The number of digital outputs available at the connections will vary, depending on the
device, see "Pin assignment of the connections", page 14. If the allocated event occurs
in the read process, then the corresponding digital output is live.
In each case, the digital outputs are short-circuit protected and overcurrent protected.
Switching behavior: PNP or NPN or push/pull
Electrical values
The sum current (100 mA) for all digital outputs is identical.
PNP HIGH: UV −3 V; LOW: 0 V
NPN HIGH: UV; LOW: ≤ 3 V
Push/pull HIGH: UV −3 V; LOW: ≤ 3 V
In the case of a push/pull sensor, the signal must be inverted in the control system in
order to obtain the same result as a sensor with NPN switching behavior.
