Product Description

The SICK 1221031 (KTS-WS41141142ZZZZ) is a high-performance contrast sensor from the renowned KTS Core family, specifically designed for precision detection in demanding industrial environments. Utilizing a powerful RGB LED light source, the sensor automatically selects the optimal emitted light color to maximize contrast between marks and backgrounds, even on challenging high-gloss or multi-colored materials.

Housed in a rugged VISTAL® casing, this “Easy Teach” device offers a space-saving “Middle” housing design with dimensions of 26 mm x 62 mm x 47.5 mm. It operates with a remarkable switching frequency of 25 kHz and a response time of just 20 µs, ensuring accurate mark detection on high-speed production lines. The 2-point teach-in process allows for rapid commissioning, while the 7-segment display provides clear feedback during setup. With an IP67 rating and a wide operating temperature range of -20 °C to +60 °C, the 1221031 delivers reliable, long-term performance in packaging, printing, and labeling applications where high gray-line resolution and minimal jitter are critical for process stability.

Key Performance Features

• High-Speed Processing: 25 kHz switching frequency and 20 µs response time for rapid machine cycles.
• Automatic Color Selection: RGB LED technology automatically picks the best light color (Red, Green, or Blue) for the highest contrast.
• Precise Light Spot: Small, vertical 1.2 mm x 3.9 mm light spot ensures pinpoint accuracy on small print marks.
• Rugged Construction: VISTAL® housing provides superior mechanical stability and chemical resistance compared to standard plastics.
• Simplified Setup: 2-point teach-in mode and a 5-step bar graph display for intuitive sensitivity adjustment.
• Flexible Output: Push-pull switching (PNP/NPN) allows for universal integration into various PLC architectures.

Ideal Applications

• Print Mark Detection: Precise alignment of cutting and folding processes in the printing industry.
• Packaging Machinery: Control of tube filling, labeling, and foil positioning.
• Food & Beverage: High-speed detection of registration marks on glossy packaging materials.
• Quality Control: Sorting and checking tasks based on color contrast or gray-scale differences.
• Pharma Industry: Monitoring and synchronization of blister pack and carton labeling.
