SICK KTS-WB9114114IZZZZ KTS Contrast Sensor
Description
KTS-WB9114114IZZZZ is a SICK KTS contrast sensor (part no. 1078851) that detects printed marks, labels and colour differences on moving material. The catalogue summary lists: light source: LED; communication interface: -; device type: Standard; sensing distance: 13 mm; switching output: Push-pull: PNP/NPN.
KTS-WB9114114IZZZZ: function, principle and typical use
Contrast sensors compare the light reflected from a mark with the light reflected from the background. They are used to find print marks on packaging film, register labels or detect edges, and respond to differences that a normal photoelectric sensor misses.
The light source (white, RGB or UV LED) decides which contrasts can be seen. Switching distance is tied to the optics: the sensor works at a defined distance from the material, within a stated tolerance, so mounting height needs to be checked as carefully as the electrical connection. RGB or white light sources compare colours differently; a single white LED may not distinguish two similar shades that an RGB source can.

Electrically and for the interface, the listed values are current < 100 mA; supply 10.8 V DC … 28.8 V DC; outputs push-pull: PNP/NPN; response time 10 µs; frequency 50 kHz.
Mechanical and environmental data for this type: housing: VISTAL®; wavelength: 470 nm, 525 nm, 625 nm; dimensions: 26 mm x 62 mm x 47.5 mm; operating temperature: –20 °C … +60 °C; light source: LED, RGB; weight: 68 g; enclosure rating: IP67.
For installation, hold the sensor at the nominal distance, keep it square to the web or tilted a few degrees on glossy film to avoid mirror reflection, and shield from strong ambient light.
Mount the sensor at the specified distance within tolerance, since the contrast is evaluated only inside that window.

About brand
SICK is the German maker of industrial sensors: photoelectric and proximity sensors, safety laser scanners and light curtains, encoders, distance sensors, code readers and gas analysers. Erwin Sick, an optics engineer, founded it in Munich in 1946, and in 1952 it introduced its first marketable accident-prevention light curtain, which protected press operators by stopping the machine when a hand broke the light beam. The company moved to Waldkirch in the Black Forest in 1956 and is still headquartered there. It is a privately held company, and has been an Aktiengesellschaft (AG) since 1996.

Milestones
- 1946: Erwin Sick receives a licence to run his engineering firm in Munich.
- 1952: The first marketable accident-prevention light curtain is presented in Hanover and goes into series production.
- 1956: The company moves to Waldkirch with 25 employees.

Choosing a SICK sensor
For object detection, the sensing principle comes first. A retro-reflective sensor (WL series) sends light to a reflector and switches when an object breaks the beam; it is reliable over long distances and easy to align. A sensor with background suppression (WTB series) detects an object at a set distance and ignores what is behind it, which suits conveyors with shiny or dark backgrounds. A through-beam pair (WS/WE) gives the longest range and the highest reliability in dust. For transparent bottles and film, use a model built for transparent objects (for example WL12G-3B or WL150-P420). The digits in the code also matter: "P" usually means a PNP output and "N" NPN, and the last digits set the connector or cable. For machine guarding, a safety laser scanner such as nanoScan3 or microScan3 protects an area, while a safety controller such as Flexi Soft combines several safety devices.
Where SICK products are used
In Oman and the GCC, SICK sensors are used in packaging and bottling lines, food and beverage plants, logistics and airport baggage handling, cement and steel plants, ports and cranes, automated warehouses, and on machines built by European OEMs. SICK safety scanners guard robots and automated guided vehicles, and its encoders give position feedback on motors, hoists and conveyors.

Ordering SICK products: what we need
Send the type code and the 7-digit SICK part number from the label (for example WTB12-3P2431 together with its part number). For a replacement sensor, add the output (PNP or NPN), connection (M8, M12 or cable) and sensing distance. For encoders, add the interface (incremental, SSI, PROFIBUS, PROFINET), resolution and shaft type. For safety scanners, tell us the model and whether the existing configuration needs to be kept.
