Product Description

The SICK 1071947 (KTM-MN31181P) is a high-performance, mini contrast sensor designed for precision detection in space-critical industrial environments. As part of the KTM Prime series, this sensor utilizes a white LED light source to reliably detect even the smallest contrast differences between marks and backgrounds, regardless of color or surface gloss. Its compact housing (12 mm x 31.5 mm x 21 mm) allows for seamless integration into tight machine designs where traditional contrast sensors would be too large.

Engineered for high-speed automated processes, the KTM-MN31181P boasts a remarkable switching frequency of 15 kHz and a rapid response time of 32 µs, ensuring accurate positioning at high web speeds. The device features an intuitive 2-point teach-in method via a physical button, enabling quick setup and high process reliability. With its rugged IP67-rated plastic housing and NPN switching output, this sensor provides a cost-effective and durable solution for modern packaging and printing applications that demand consistent, long-term performance.

Key Performance Features

• High-Speed Processing: 15 kHz switching frequency allows for the detection of marks on rapidly moving webs.
• Compact Design: Small footprint ideal for installation in restricted spaces within machinery.
• Advanced White LED Technology: Provides superior contrast resolution, allowing for the detection of various color combinations.
• User-Friendly Setup: Simple 2-point static/dynamic teach-in ensures the sensor is ready for operation in seconds.
• Rugged Reliability: IP67 enclosure rating ensures protection against dust and water ingress in harsh industrial environments.
• Precision Sensing: A round light spot of Ø 2 mm at 12.5 mm ensures precise target acquisition.

Ideal Applications

• Packaging Industry: Accurate detection of print marks on film, labels, and cardboard.
• Printing Systems: Synchronization of cutting and folding processes based on registration marks.
• Labeling Machines: High-speed placement and verification of labels on bottles or containers.
• Splice Detection: Identifying tape or joint sections on continuous material rolls.
• Small Component Assembly: Presence detection of small parts based on contrast differences.
