Product Description

The SICK 1070053, also known as the KTM-MB31112P, is a high-performance “Core” series contrast sensor designed for precise detection in space-restricted industrial environments. Housed in a compact 12mm x 31.5mm x 21mm plastic casing, this sensor utilizes a white LED light source to provide exceptional grayscale resolution, allowing it to distinguish between subtle contrast differences on various surfaces.

Engineered for high-speed applications, the KTM-MB31112P boasts a switching frequency of 10 kHz and a rapid response time of 50 µs, ensuring accurate mark detection even on fast-moving production lines. The device features a round light spot with a 2 mm diameter at its 12.5 mm focal point, optimized for detecting small registration marks. Setup is simplified via a manual potentiometer, providing a robust and intuitive adjustment method that is less prone to accidental changes in harsh environments. With its dual PNP/NPN switching output and IP67 protection rating, this sensor offers versatile integration and long-term reliability for modern automated packaging and printing processes.

Key Performance Features

• High-Speed Processing: 10 kHz switching frequency allows for the detection of marks on rapidly moving webs.
• Ultra-Compact Housing: Small footprint (12 mm wide) enables installation in tight machine spaces where standard sensors cannot fit.
• Flexible Output: Integrated PNP and NPN switching outputs provide compatibility with various PLC and controller architectures.
• Stable Grayscale Detection: The white LED light source ensures reliable detection of diverse color combinations and faint contrast marks.
• Rugged Design: IP67-rated plastic housing provides resistance to dust and temporary water immersion, suitable for demanding industrial conditions.
• Simple Commissioning: Manual adjustment via a potentiometer allows for quick, tool-based sensitivity setting without complex menus.

Ideal Applications

• Packaging Industry: Detection of registration marks on films, foils, and cardboard for cutting and folding accuracy.
• Printing Equipment: Monitoring print marks to ensure color alignment and synchronization in high-speed presses.
• Labeling Machines: Precise positioning of labels on bottles, containers, and various consumer goods.
• Splice Detection: Identifying tape or material joins in continuous web processing to prevent downstream errors.
• Tube Filling: Aligning tubes based on orientation marks prior to sealing in the pharmaceutical and cosmetic industries.
